Why does a blood clot come off Causes of symptoms, diagnosis and treatment

The thrombus may be parietal, and may be floating. If a blood clot is located near a cholesterol plaque, then it will come off less likely than a floating thrombus. The latter “sits” on a thin leg, which has a weak attachment with a vascular wall. Floating blood clots most often lead to the development of pulmonary embolism and strokes.

Wandering blood clots, which pose a serious threat to life, may also be present in the body.

A blood clot can come off as a result of the following influences:

The blood flow is greatly accelerated.

A blood clot formed in a wide vessel.

The thrombus leg is weak.

After separation, a blood clot begins a journey with a blood stream through the vascular bed. At this time, it often breaks up into small fractions. Once in a vessel that does not exceed its size, a blood clot clogs it. This entails a stoppage of blood flow and disrupts the nutrition of the limb or organ. This pathological condition is called occlusion.

If it is timely recognized that a blood clot has come off in a person, this can save his life.

The consequences of the disaster that may occur are as follows:

A clot in a brain vessel is called a stroke. Its main features: speech disorders, facial asymmetry, impaired coordination of movements, paralysis of limbs. If a blood clot enters the vein of the brain, then the person will suffer from dizziness, headaches, blurred vision, etc.

If the thrombus enters the coronary arteries, the patient develops myocardial infarction. A person experiences severe pain in the region of the heart, in the neck, stomach, between the shoulder blades.

Mesenteric thrombus leads to intestinal vascular embolism. At the same time, a person experiences severe abdominal pain, which occurs unexpectedly, against the background of absolute well-being. This is the reason for the immediate call of the ambulance team. If a person is not provided with emergency assistance, this will lead to the death of intestinal tissue, infection of the peritoneal cavity and death.

When a blood clot clogs a vessel that feeds a limb, this can entail its gangrene. Symptoms of embolism of the veins of the arms or legs are severe pain, blue tissue in an appropriate place.

Blockage of a thrombus of a pulmonary artery is the most serious condition, which often ends with the death of the patient. A thrombus may enter the pulmonary artery from veins of the lower extremities. Most often this happens against the background of thrombophlebitis. With pulmonary embolism, a person can die in a few minutes from heart or lung failure.

If a person has one or more of the above symptoms, you should not hesitate to contact a doctor. When there is a suspicion of thrombosis, it is necessary to tell the doctor about this, which will facilitate the diagnosis. If a person knows that he is suffering from atherosclerosis, thrombophlebitis, coronary heart disease and other diseases that are associated with a risk of a blood clot, you should inform your doctor.

It is worth noting that about 50% of people who had thrombosis did not experience any pathological symptoms until an acute circulatory disturbance occurred.

The following symptoms can help you find a blood clot:

Most often, blood clots are localized in the veins of the lower extremities. A developed system of veins that appear under the skin can suggest the idea of ​​thrombosis. The vessels can be compacted, sometimes they become inflamed, which can be seen by the redness of the skin and the pain that occurs when you touch them. If you touch this area, you can feel the heat.

A blood clot that has formed in deep veins can make itself felt by swelling in a characteristic place, general malaise, and unexplained jumps in body temperature.

If a person has a blood clot come off, then it is impossible to delay the call of the ambulance crew. Moreover, without special equipment even a doctor cannot make an accurate diagnosis. Therefore, the victim must be hospitalized urgently.

There may be two treatment regimens for thrombosis: either the patient is prescribed medication correction, or they are referred for surgery.

Drug therapy includes:

The appointment of anticoagulants. These drugs contribute to blood thinning (Heparin, Warfarin).

Course treatment with statins.

The appointment of thrombolytics, which are necessary for the dissolution of the thrombus.

If the problem cannot be solved with the help of medicines, or a person develops complications of thrombosis, he is shown an operation called thrombectomy. It is also possible to set up special cava filters that will “catch” blood clots, preventing them from clogging vital vessels.

In people whose blood relatives suffered from thrombosis, the risk of developing a similar disease will be high. Therefore, you should regularly be examined by a doctor to detect dangerous vascular growths. Modern medicine has all the necessary tools to detect a blood clot and prevent its separation.

If a person’s blood is characterized by increased coagulability, he will be prescribed drugs (antiplatelet agents). Sometimes they need to be taken for life. It should be noted that only a doctor can recommend them, otherwise you can cause serious harm to your own health.

If the doctor diagnoses a blood clot, which can come off with a high degree of probability, then the patient is urgently hospitalized and prepared for surgery.

People with thrombosis should clearly follow medical instructions. They are not recommended to take a hot bath, go to saunas and baths, since all these procedures help to strengthen the blood flow through the vessels. The ban is also imposed on visits to massage rooms and on the use of warming compresses.

So that the blood does not stagnate in the veins, it is necessary to move as much as possible, engage in physical culture, walk a lot.

If the patient has a risk of separation of the thrombus, then he is shown strict bed rest. Self-treatment of thrombosis or expectant management in this case is unacceptable.

A menu with foods that lower blood cholesterol should be a priority. This will prevent the formation of atherosclerotic deposits on the vessels, and therefore reduce the risk of thrombosis. For this purpose, you can include marine fish, seafood, broccoli, spinach, young potatoes, dairy products in the diet.

1. Inexplicable fatigue

Blood clots are blood clots that clog arteries and veins. In most cases, blood clots occur in the vessels of the legs. The causes of blockage of blood vessels are as follows:

  • physical damage to the vascular walls;
  • slowed blood circulation;
  • the appearance of atherosclerotic plaques;
  • increased blood clotting;
  • consequences of surgical intervention;
  • prolonged immobilized position of the patient’s body.

Blood clots in arteries appear due to the deposition of cholesterol on the walls of blood vessels, which causes the formation of plaques. Fibrins and platelets accumulate around the plaque, a clot forms that completely covers the lumen of the vessel. At the very beginning of its appearance, the thrombus is soft, but gradually acquires a dense structure. Blood clots in the veins occur against blood diseases such as thrombophlebitis and phlebothrombosis.

The most dangerous for a person’s life if a blood clot comes off in large blood vessels. The consequences of separation can be as follows:

  • blockage of large blood vessels;
  • heart attack;
  • thromboembolism of the lungs;
  • stroke;
  • death of the patient.

Clots cannot come off in small blood vessels, because the blood moves through them with insufficient speed and pressure.

Blood clots come in many forms, it all depends on where they are located:

  1. Parietal formations form on the vascular walls, they cannot come off, since they do not impede the movement of blood.
  2. Occlusive clots completely cover the lumen. They interfere with free blood flow.
  3. Floating thrombi with a thin base in the base are dangerous. They come off easily and cause obstruction of the artery in the lungs.
  4. Emboluses are moving clots that circulate freely with the flow of blood.

The reasons for the separation of blood clots can be as follows:

  • obstructed blood flow and high blood flow;
  • the presence of a thrombus in the veins of the legs, heart cavity and arteries.

It should be understood that when a clot comes off, it can be divided into many formations and clog several vessels at once.

Symptoms of a detached blood clot in patients are different, it depends on in which vessel the blockage occurred. If there is a separation in the vessels of the brain, a stroke should be assumed. The patient has a violation of speech, swallowing, facial asymmetry. With serious damage to the vessels of the brain, there may be a violation of tactile sensitivity and movements.

Signs of a detached thrombus in the coronary artery, as well as its blockage and damage will be slightly different. Pressing and acute pain in the chest occur, myocardial infarction is possible. Basically, such pains are localized in the area of ​​the heart, which means damage to the heart vessels. Sometimes pain can be given to the lower jaw, stomach, neck, arms and interscapular region.

A blood clot clogging a vessel in the intestine causes peritonitis and severe abdominal pain. When a blood clot in a leg can come off and clog vessels, then blue limbs, a decrease in temperature in the injured leg, redness, swelling and severe pain are observed. With untimely treatment, gangrene develops, due to which the leg can be amputated. Blockage of the veins of the lower extremities occurs gradually, so they usually manage to cure it. The treatment is mainly surgical.

Blockage of blood vessels in the lungs develops with lightning speed. The patient has oxygen starvation, blue skin, prolonged dyspnea, cardiac arrest and breathing. In this case, you need to urgently call an ambulance. Only doctors know what to do, and whether it is possible to save a person with pulmonary embolism. If help is not provided on time, embolism leads to the death of the patient.

Causes and risk factors

Thrombosis can be acute or chronic. In the latter case, the sluggish course of the disease alternates with periods of exacerbation and remission.

Venous thrombosis is called phlebothrombosis. In this case, a blood clot forms in the deep vein cavity. Most often localization in the lower extremities. Blood clots in vessels may have a different location:

  • portal vein of the liver;
  • renal vein;
  • jugular vein;
  • veins of a hemorrhoid;
  • cavernous sinus.

To check for thrombosis and assess the risk of complications, the following types of diagnostics are used:

  • Visual inspection, blood test. Platelet count, leukocyte count, inflammation are assessed.
  • Coagulogram. The indicator of coagulability, the ratio of proteins is determined.
  • Research on tumor markers.
  • Ultrasound examination, dopplerography. Used to assess the state of vascular and venous walls and blood flow.
  • Duplex scanning of blood vessels. The level of blood viscosity, the rate of circulation, the likelihood of thromboembolism are found out.
  • X-ray examination using a contrast medium. Allows you to check the vessels for the presence of a blood clot, to clarify its size, to display a three-dimensional image of the vessel.
  • Radionuclide scan. The method is similar to angiography, but labeled albumin is used instead of contrast medium. Used to refine the results of other studies.
  • CT scan. It shows the presence of inflammation, the condition of veins, valves and vascular walls.

To find out if there are blood clots in the body, a comprehensive examination is used. It also includes functional tests (Homans, Lowenberg, Pratt, Delbe-Pertes). The need for different types of diagnosis is determined by the attending physician.

Other causes of thrombosis:

  • high coagulability of blood;
  • violation of normal blood circulation in the affected area (this is possible after surgery or due to a sedentary lifestyle);
  • damage to the walls of the vessel due to trauma or an infectious-inflammatory process;
  • diseases of the cardiovascular system (atherosclerosis, heart failure);
  • cancers leading to vascular compression.

An important role in the formation of blood clots is played by varicose veins, phlebitis and thrombophlebitis.

The following populations are at risk of clogging with a clot of a vessel:

  • people after surgery on the heart or blood vessels;
  • patients older than 40 years;
  • obese people;
  • leading unhealthy lifestyles (lack of physical activity, smoking, drinking alcohol, unhealthy diet);
  • taking hormonal drugs for a long time;
  • cancer patients;
  • with a diagnosis of varicose veins;
  • with heart failure or hypertension;
  • pregnant.

The most dangerous to human life is a blood clot, which formed in a large vessel. The blood flow is high, there is a risk of profuse internal bleeding, which will cause a person’s death. Also increases the likelihood of delivering a blood clot (in case of separation) to the heart and lungs, which often ends in death.

How do blood clots come off? After formation, they begin to gradually increase in size, but at the same time are attached to the wall on a thin leg. First, the clot can partially block the vessel, and then completely lead to complete blockage. In the latter case, under pressure from the blood, it breaks off and wanders through the bloodstream until it clogs the artery.

What are the reasons for the separation of a blood clot? Such pathological conditions can provoke this:

  • high speed of blood flow;
  • localization of a clot in a wide vessel;
  • increased blood pressure;
  • fever, high body temperature, infectious diseases;
  • excessive physical strain.

The outcome depends on the affected area, as well as the speed of care. If a blood clot clogged the vessels of the brain, then a stroke is likely, a heart – a heart attack, lungs – suffocation, a spinal cord – paralysis, peripheral arteries – tissue necrosis.

To accurately determine that a blood clot has come off, an examination is performed. The diagnosis can be made on the basis of laboratory and instrumental diagnostic methods:

  • compression ultrasonography (with vein thrombosis of the lower extremities);
  • determination of the level of D-dimer (the result with thrombosis is always positive);
  • lung scintigraphy (if pulmonary embolism is suspected);
  • CT of the lungs, including multispiral CT with contrast;
  • ultrasonic duplex scanning;
  • MRI angiography.

The choice of methodology depends on the diagnosed disease. To obtain information about the state of blood flow and detect thrombosis, ultrasound duplex scanning is the most informative. But this technique can only be used when examining the veins of the neck and limbs.

Multispiral CT should be used in case of thrombosis of the vessels of the chest or abdominal cavity, in particular, with pulmonary embolism. MRI angiography is informative for blockage of cerebral vessels.

The Society of Cardiology, created in Europe, has developed its own strategy for the prevention of thrombosis.

It was compiled taking into account the main risk factors leading to the development of the disease, and was called “0-3-5-140-5-3-0”:

0 – completely abandon such a bad habit as smoking. Moreover, this statement applies even to those people who are passive smokers. Inhaling tobacco smoke means being at risk for thrombosis.

3 – every day you need to walk at least 3 km on foot, as well as play sports for 30 minutes.

5 – every day to eat vegetables and fruits, 5 servings.

140 – maximum pressure should not exceed 140/90 mm. Hg. Art.

5 – the indicator of total cholesterol in the blood should not exceed 5 mmol/l.

3 – the level of low density lipids should be at least 3 mmol/l.

0 – do not get better, do not get diabetes.

If you follow this “health code”, then the risks of developing thrombosis are significantly reduced.

Sometimes it happens that a person learns about thrombosis only in a hospital ward. Often the disease has an asymptomatic course. Therefore, the prevention of thrombosis should become a way of life. In addition, you should carefully listen to your body, which always gives signals of trouble.

When thrombosis is detected on time, surgical intervention and health problems can be avoided. If a person is in one of the risk groups, you need to regularly undergo an examination aimed at identifying blood diseases. You can do this using the following methods:

  • thrombin generation test;
  • thrombodynamics;
  • prothrombin test.

nepriyatnosti s trombom - Why does a blood clot come off Causes of symptoms, diagnosis and treatment

The appearance of symptoms of a detached blood clot is the main sign of the neglect of the disease. The risk group includes:

  • men who have reached the age of 40, as their blood coagulation index changes;
  • women after menopause;
  • overweight, which several times increases the risk of blood clots, since cholesterol is deposited on the walls of blood vessels;
  • people with the wrong diet;
  • drinking a lot of alcohol;
  • people with sedentary work or low physical activity;
  • pregnant and newly born women;
  • patients after surgical operations of the abdominal cavity and large joints;
  • oncological patients.

The risk group includes people with diseases that lead to increased blood coagulation.

The most dangerous consequences of thrombosis are the separation of a thrombus. The separation of the formed blood clots from the walls of blood vessels can lead to the following serious complications:

  • Stroke – occurs with the aggregation of blood clots in the arteries that feed the brain;
  • Heart attack – develops as a result of damage to large vessels of the heart;
  • Thromboembolism of the lungs – acute circulatory disturbance in the lung tissue;
  • Thromboembolism of the lower extremities – damage to the deep or superficial veins on the legs.

Having dealt with the question of what it means – a blood clot has come off, we will consider options for further development of the situation. In approximately 50-60% of cases, when the capillaries and small peripheral vessels are blocked, spontaneous dissolution (lysis) of the thrombus occurs after some time. However, with damage to the vessels of the brain, heart and lungs without emergency medical care, a fatal outcome is inevitable.

85% of patients are diagnosed with thromboembolism of the lower extremities, accompanied by the accumulation of blood clots in the sural sinuses of the lower leg – blind muscle cavities in the calf and ankles. In the absence of timely therapy, necrosis of tissues lacking nutrition and oxygen occurs, ending in gangrene and death.

From what are formed

Blood clots form because when a vessel is damaged, a protective reaction of the body is activated. The process is aimed at stopping bleeding.

With skin damage, the integrity of small vessels is impaired. The formation of fibrin filaments is activated. Blood stops due to the closure of torn capillaries with small blood clots. It also happens inside the body: when vascular damage occurs, clogging clots form. They are composed of fibrin, white blood cells, red blood cells and platelets.

The process of blood clots in the blood coagulation scheme is an integral part of life support. In the absence of pathologies does not pose a threat to health. When the process is disturbed, blood clots do not dissolve, increase, their number grows. They can completely close the lumen of the vessel. The main causes of thrombosis:

  • pathology of the vascular wall;
  • blood flow disorders;
  • increase in blood viscosity.

These disorders can be triggered by genetic disorders, a sedentary lifestyle. Other risk factors:

  • varicose veins;
  • taking hormonal drugs;
  • improper diet;
  • smoking;
  • dehydration;
  • stress;
  • oncology;
  • autoimmune diseases;
  • diabetes;
  • liver disease;
  • pregnancy.

Another cause of blood clots in vessels is an excess of cholesterol. Plaques form in the vessels and calcium deposits form. The vessels become fragile, their walls ulcerate. Clumps grow in damaged areas.

Why comes off

  • When the parietal clot is located in a vessel with a large clearance, blood circulation is not disturbed. It comes off because its base is exposed to blood flow.
  • A clot with a loose structure will come off faster. It mainly consists of fibrin strands and contains few platelets, has a weak base.
  • A blood clot can come off at a high speed of blood flow.

More often thrombi are exposed to detachment, the body and tail of which freely move in the vessel.

A clot can come off under the influence of additional factors: physical overstrain, obesity, varicose veins, oncology, trauma, septic lesions.

How to recognize a blood clot

The danger of the disease is that the symptoms of thrombosis are not always pronounced. Often the disease is difficult to detect, and the separation of the formed clot occurs suddenly. With different localization, symptoms of a different nature appear. Signs of a blood clot in the body:

  • Chronic feeling of tiredness.
  • Dryness in the mouth.
  • Feeling of numbness.
  • Swelling or soreness of the extremities.
  • Heating and itching of the affected area.
  • Local change in the shade of the skin.
  • Shortness of breath and discomfort, chest pain, unexplained cough are signs of thrombosis in the lungs. Symptoms of a blood clot in the heart may be similar.
  • Fever and sweating. Appears with thrombosis of the kidneys.
  • Dizziness, loss of consciousness.
  • Acceleration of heart rate. It is observed when the clot moves to the lungs. With this localization of the thrombus, the symptoms and first signs are characterized by a lack of oxygen. The heart works in an accelerated mode, trying to compensate for the condition.
  • Strong headache.
  • The formation of red veins. They can be confused with a rash, but with thrombosis they are warmer.
  • Pain in the calves, increasing gradually. It can hold for several days or weeks.

The above symptoms may be manifestations of thromboembolism. If they are detected, it is recommended to undergo a preventive examination, to check for blood clots in the veins and vessels.

First aid

If the patient has symptoms of a blood clot, the following actions should be taken:

  • urgently put the patient to bed and help him to take a comfortable position;
  • call a cardiological emergency team;
  • it is advisable to apply a cooling compress to the damaged area.

The place where the blood clot came off is strictly forbidden to warm. Prior to the arrival of the cardiological team, the patient can be given analgesics and antispasmodics to relieve pain and cramping. After the diagnosis of thrombosis is made, the patient should always keep these medications with him. A predisposition to blood clots in blood vessels can be determined in advance. In this case, the doctor will be able to tell the patient and relatives how to act in case of a detached thrombus.

If a person has a blood clot come off, then you can not hesitate. Every minute counts, especially with pulmonary embolism (pulmonary embolism), when help is needed for 2-3 minutes.

It is worth noting that at home it is impossible to help the victim. If a blood clot burst, you need to call an ambulance, the patient needs hospitalization. First aid is the introduction of anticoagulants, then treatment is carried out depending on the severity of the condition and the results of the examination.

Which doctor treats a blood clot?

If a blood clot comes off, a vascular surgeon can help the patient. A phlebologist is involved in the treatment of thrombosis and other venous diseases.

After the blood clot has come off, physicians have a maximum of 2 hours (if he did not provoke a pulmonary embolism) to dissolve it and prevent its increase. Conservative and operational techniques may be used.

In the first case, the following groups of medicines are used:

  • blood thinners (anticoagulants) – Heparin, Warfarin, Dalteparin, Nadroparin, Pradaxa, Xarelto;
  • contributing to the dissolution of the thrombus (thrombolytics) – Streptokinase, Thromboflux, Fibrinolysin.

Medicines are injected. Tableted forms are used after stopping the acute period. After normalizing the patient’s condition, inpatient treatment and the implementation of preventive measures are indicated.

In emergency situations, when blood circulation cannot be restored, the patient is prepared for surgery. A blood clot is removed mechanically using a catheter. To expand the damaged vessel, a stent can be installed in it. In some cases, shunting is used. This is the creation of an additional vessel, bypassing the clogged.

For the period of treatment, it is important to adhere to bed rest. After surgery, you need to start physical activity correctly.

The formation of a blood clot in a vein (thrombosis) is a protective reaction of the body aimed at maintaining or restoring the integrity of the vessel. In the area of ​​its damage, there is a local decay of platelets and the accumulation of thrombin, an enzyme that activates the process of blood coagulation. Under the action of thrombin, the fibrinogen contained in the biological fluid is converted to fibrin, a high molecular weight protein whose fibers form the basis of a blood clot.

otryv tromba vnutri ven - Why does a blood clot come off Causes of symptoms, diagnosis and treatment

Separation of a blood clot inside a vein

The resulting thrombus is firmly fixed on the wall of the vein at the site of damage, hermetically clogging it. In the cells of the formed vein network, blood cells gradually accumulate. Under normal conditions, the structure is compacted and becomes part of the vascular wall.

However, fibrin formations can appear in intact vessels as a result of increased blood coagulation. The main causes of hypercoagulation include:

  • Varicose vein disease;
  • High blood cholesterol;
  • Endocrine disorders, diabetes mellitus;
  • Unstable blood pressure;
  • Allergic reactions;
  • Severe poisoning, prolonged exposure to toxins on the body;
  • Long-term use of hormonal drugs;
  • Benign and malignant neoplasms;
  • Unhealthy Lifestyle;
  • Stress, accompanied by a regular release of adrenaline, which slows down blood clotting.
  • Call an ambulance immediately;
  • Lay or seat the victim, ensuring absolute peace and air flow. If a blood clot burst, you need to avo >pervaya pomoshch pri otryve tromba na noge - Why does a blood clot come off Causes of symptoms, diagnosis and treatment

    First aid for separation of a blood clot on the leg

    If a stroke or heart attack is suspected, the patient is urgently given drugs that support the work of the heart and brain. In-patient treatment includes a set of measures aimed at dissolving a blood clot and normalizing the rheological properties of blood:

    • Intravenous administration of anticoagulants (usually heparin preparations);
    • Local and systemic therapy with thrombolytics, antiplatelet agents, phlebotonics (Streptokinase, Hepatrombin, Warfarin, Fibrinolysin);
    • Taking antibiotics and non-steroidal anti-inflammatory drugs for acute inflammation and infection of affected tissues;
    • Installation in the cavity of the affected vein of a special filter that prevents further migration of fibrin formation;
    • Thrombus removal surgery in severe cases.

    If the blood clot comes off – what to do?

    In order to avoid the formation of blood clots and their separation, it is necessary to observe preventive measures. This is especially necessary if a person is at risk. Preventive measures include:

    1. Compliance with diet and proper diet. Less cholesterol-rich foods should be eaten less. You can’t eat constantly rich broths, margarine, fried foods. You need to eat foods that lower blood coagulation, for example, citrus fruits, broccoli, cherries, green tea.
    2. Take anticoagulants, such as Aspirin. It lowers blood coagulation. However, it can be taken only as directed by a doctor.
    3. Physical activity is required, cardio training is needed daily. This will help reduce blood coagulation, strengthen the heart muscle, speed up blood circulation.
    4. If you make regular long flights and trips, you need to wear special compression underwear.

    The consequences of a blood clot in the heart and lungs can be the most deplorable, so you need to regularly visit a doctor and treat the disease.

    If a thrombus is discovered in time, the dangerous consequences of its movement can be prevented. Signs of a detached blood clot:

    • The location in the brain is characterized by speech disorder, distortion of facial symmetry, and a sharp headache. Possible loss of coordination, sensitivity. Sometimes there is paralysis, visual disturbance, pain in the neck.
    • When blocking a torn clot of heart vessels, acute heart pain is manifested. It is possible to localize the pain syndrome in the area of ​​the shoulder blades, neck, abdomen, limbs, sometimes in the lower jaw.
    • Localization in the intestine is characterized by severe pain with the further development of necrosis, peritonitis.
    • Blocking the vessels of the limbs is characterized by a change in skin color, swelling, pain.
    • Blocked arteries in the lungs. With a blood clot, the symptoms manifest themselves as a lack of air, blue skin.

    If a blood clot comes off, the condition is always accompanied by oxygen starvation of the affected organ. Nutrient deficiency develops due to circulatory disorders.

    To prevent thrombosis and blood clot separation in case of vascular disease and varicose veins, the attending physician may recommend wearing compression underwear and taking blood thinners. Also recommended:

    • physical activity, moderate sports loads;
    • adherence to a diet that restricts fatty and fried foods.

    It is recommended to undergo annual diagnostics, regularly undergo examinations by a therapist and phlebologist, even in the absence of signs of the disease. This will allow timely detection of blood clots in the vessels and take the necessary measures to prevent dangerous complications.

    Preventive measures include the exclusion of factors due to which blood clots can form and come off. The most careful should be those at risk. Men more often than women suffer from thrombosis, as they are addicted to bad habits.

    There is a high probability of blood clots in people with a hereditary predisposition. If relatives had thrombosis, then you need to be examined once a year. With increased blood coagulability, it is worth taking antiplatelet agents or anticoagulants.

    Prevention needs to be addressed not only to those over 40 years old, but also to young people. Physical activity, especially cardio, is very helpful. At least 30 min recommended. devote a day to running or hiking. Physical education strengthens the heart muscle, normalizes blood flow and reduces blood coagulation. It is also the prevention of obesity.

    People with varicose veins of the lower extremities should wear compression underwear. It favorably affects the venous system, inhibits thrombus formation. Tight bandage may be required.

    Other, no less important measures to prevent blood clot separation:

    • to refuse from bad habits;
    • control weight within normal limits;
    • avoid prolonged stay in one position;
    • include more vegetables and fruits in the diet, refuse foods high in cholesterol and foods with a high concentration of vitamin K (spinach, herbs, cabbage);
    • give preference to products that reduce blood clotting (beets, cherries, raspberries, citrus fruits, cucumbers, pears, seaweed, seafood);
    • drink at least 1,5 liters of clean water;
    • strengthen the walls of blood vessels (medications suitable Detralex, Flebodia 600, Ascorutin);
    • do foot massage.

    All of these recommendations reduce the likelihood of thrombosis and associated complications.

    The separation of a blood clot and the processes occurring after this can be prevented if you carefully treat your body. If such a problem could not be avoided, the outcome depends on the speed of medical care.

    • Violation of the strength and elasticity of blood vessels as a result of natural aging of tissues and some pathologies. The fragile walls of veins and arteries cannot hold the formed clots, as a result of which they are separated from the place of attachment and transferred through the body with a blood stream;
    • Violation of the rheological properties of biological fluids. The higher the viscosity and speed of blood flow, the more difficult it is for a blood clot to resist external influences.

    Changes in these indicators most often occur under the influence of the following factors:

    • Excessive physical exertion;
    • Pregnancy;
    • Dehydration;
    • Conditions accompanied by increased body temperature, chills, fever;
    • Diabetes;
    • Errors in the diet (the use of a large amount of protein, lack of vitamins);
    • Thermal burns;
    • Diseases of the kidneys, adrenal glands, liver.

    Sometimes a wandering thrombus is formed – a formation that is only pointwise attached to the vessel wall. The main risk factors for the development of pathology include old age, overweight, a sedentary lifestyle, and the postoperative period. Due to the weak connection of the fibrin clot with the surrounding tissues, it easily separates and migrates through the bloodstream. A floating thrombus may come off due to a minor load: coughing, sneezing, abrupt change in body position.

    • Sharp chest pain;
    • Shortness of breath, inability to take a deep breath;
    • Dry cough, sometimes accompanied by hemoptysis;
    • Confusion, fainting.

    The first signs of a blood clot

    Congestion of the veins of the internal organs can be expressed in violation of digestion, nausea, vomiting, abdominal pain. All acute conditions are accompanied by a feeling of fear, panic. It is impossible to answer affirmatively the question of whether it is possible to save a person if a blood clot in the region of the heart, lungs, intestines, or kidneys comes off. Most diagnosed cases of blockage of large veins and arteries result in death or disability.

    The main signs of a detached blood clot in the leg are:

    • Discomfort and pain of varying intensity;
    • Severe swelling of the legs below the knee;
    • Local decrease or increase in temperature;
    • Change in skin tone (pallor, cyanosis, redness visible in the photo along the affected vessel);
    • Moderate gait disturbance, intermittent claudication.

Many patients complain of a feeling of heaviness in the legs, cramps and numbness. After some time, the skin on the affected limb begins to peel and darken. If untreated, necrosis of malnourished tissues and gangrene develops.

    It is often difficult to understand that a blood clot in a leg has come off, since pathological symptoms can have a weak intensity and increase gradually. However, if there is any suspicion of a clogged vessel or a change in the appearance of a limb, you should immediately consult a doctor.

    • Regularly visit a therapist or phlebologist;
    • To undergo a medical diagnosis of hypercoagulation annually (duplex ultrasound scanning, X-ray examination, coagulogram);
    • Adhere to an active lifestyle;
    • Avoid eating fatty foods, sausages, smoked meats;
    • Timely treat all diseases.

    When diagnosed with thrombosis, medications that reduce blood coagulation (Aspirin, Heparin, Clexane) should be taken. As prescribed by the doctor, it is recommended to wear compression stockings, regularly undergo physiotherapy treatment.

    There is no clear answer to the question of how a blood clot in a person comes off. The most favorable situation is when thromboembolism of the lower extremities develops. Timely treatment avoids the development of dangerous complications and death.

    How to get rid of blood clots

    If thrombosis is detected, the doctor prescribes the necessary treatment. The tactics of therapy are selected, the need for being in the hospital is determined. Treatment of deep vein thrombosis requires bed rest. If there is a danger of blocking an artery in the lungs, surgical removal of the clot is performed.

    In order to cure thrombosis, a comprehensive intake of medicines is necessary:

    • Direct anticoagulants. Assigned to reduce thrombin activity, improve the production of antithrombin III.
    • Indirect anticoagulants. Assigned to suppress prothrombin synthesis, reduce coagulation factors associated with vitamin K.
    • Thrombolytics, enzyme preparations. Accelerate the dissolution of fibrin fibers, reduce the size of formations.
    • Hemorheological active agents. They dilute blood and remove thrombosis, preventing the integration of platelets. Used to improve blood circulation.
    • Nonspecific anti-inflammatory drugs. Reduce the inflammatory process and pain.

    Independent use of drugs without consulting a doctor is unacceptable. The complex of medicines is individually compiled taking into account the clinical picture.

    When thrombophlebitis and other complications of thrombosis occur, treatment includes surgical methods. The operation is necessary with an increased risk of clot detachment, the likelihood of pulmonary embolism, in the presence of a floating clot (not attached to the walls).

    In surgery, there are several ways to remove a blood clot from blood vessels:

    • Thrombectomy Surgical removal. The disadvantage of the operation is the high probability of re-formation at the site of damage to the venous membrane.
    • The introduction of a cava filter. This is a trap that looks like the base of an umbrella. Blood passes easily through the device, and the clot cannot move further. With its large size, after getting into the trap, urgent extraction is necessary, which is a drawback of the method.
    • Crossectomy It is carried out in urgent cases. The trunk of the vein is stitched with metal clips or a clip is installed that prevents the passage of blood.

    Surgical intervention is not performed in the acute stage of the disease due to the likelihood of the formation of new clots after surgery, with severe pathologies of the heart and blood vessels, with acute infectious processes.

    Detonic – a unique medicine that helps fight hypertension at all stages of its development.

    Detonic for pressure normalization

    The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.

    Detonic not addictive and withdrawal syndrome, since all components of the product are natural.

    Detailed information about Detonic is located on the manufacturer’s page www.detonicnd.com.


    The use of traditional medicine for thrombosis should be agreed with the attending physician, as self-medication can lead to dangerous consequences. To improve the condition and thin the blood, various herbs are used:

    • Hop cones. Beneficial effect on the heart and blood vessels, have a calming effect.
    • Verbena officinalis. Natural compounds in the composition prevent platelet adhesion and help dissolve blood clots in the vessels.
    • White acacia. It is used to reduce blood density due to salicylic acid esters in the plant. Active components increase the tone of the veins.
    • Honey and onions (juice). They are natural anticoagulants that prevent the formation of clots.

    Diet for the disease is aimed at reducing weight, reducing blood viscosity and strengthening blood vessels.

    Blood clot classification

    There are several types of blood clots. By composition and structural features:

    • White – mainly consist of white blood cells and platelets, coagulate in arteries and increase in size over time;
    • Red – contain a large number of red blood cells, form in the veins with slow blood flow;
    • Mixed – have a multilayer structure, consist of a “head” (white thrombus) and a “tail” (red thrombus) fixed to the vessel wall;
    • Hyaline – contain a low concentration of fibrin and resemble hyaline – a glassy jelly-like substance.

    By size and localization:

    • Parietal – located along the venous or arterial walls and affect mainly the vessels of the heart and lower extremities;
    • Clogging – completely block the lumen of the vessel, are formed in the process of rap >raznovidnosti trombov - Why does a blood clot come off Causes of symptoms, diagnosis and treatment


    With the separation of the thrombus in the event of a stop in small vessels, a gradual dissolution of the clot sometimes occurs. If you enter the deep veins, heart, brain, intestines and lungs and in the absence of medical care, death occurs.

    The prognosis depends on how quickly assistance is provided to the victim. In many cases, the patient’s life can be saved by taking therapeutic action in the first 5-30 minutes. If you suspect an embolism, you must call an ambulance, fix the time of the alleged separation of the thrombus. The patient needs to ensure peace.

    It is impossible to predict which organ the detached clots will fall into. When stopping in the vessels of the hands and feet, necrosis and gangrene develops, in the brain system – stroke, in the heart – myocardial infarction, in the abdominal aorta – tissue necrosis. Stopping in the arteries of the lungs is often fatal.

    Vein thrombosis of the extremities is weak, symptoms gradually increase. This is the danger, because with untimely diagnosis, a fatal outcome is possible. It is important to immediately consult a doctor at the slightest suspicion of thromboembolism.

    Arterial and vascular thrombosis potentially threatens a heart attack to any organ. To avoid dangerous consequences, it is recommended to carry out preventive measures.
