Thrombose Thrombosis | Definition of Thrombosis by Merriam-Webster
Thrombosis is the formation of a blood clot inside a blood vesselobstructing the flow trophische Ulkusbehandlung Patch blood through the circulatory system. When a blood vessel is injured, Thrombose, the body uses platelets thrombocytes and fibrin to form a blood clot to prevent blood Thrombose. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions.
A clot, or a piece of the clot, that breaks Thrombose and begins to travel around the body is known as an embolus. Thrombosis may occur in veins venous thrombosis or in arteries, Thrombose. Venous thrombosis leads to congestion of the affected part of the body, while arterial thrombosis and rarely severe venous thrombosis affects the blood supply and leads to damage of the tissue supplied by that artery ischemia and necrosis, Thrombose.
A piece of either an arterial or a venous thrombus can break off as an embolus which can travel through the circulation and lodge somewhere else as Thrombose embolism. This type Thrombose embolism is known as a thromboembolism. Complications can arise when a venous thromboembolism commonly called a VTE lodges in the lung as a pulmonary embolism. An arterial embolus may travel Thrombose down Thrombose affected blood vessel where it can lodge as an embolism. Thrombosis is generally defined Thrombose the type of Thrombose vessel affected arterial or venous thrombosis and the precise location of the blood vessel or the organ supplied by it.
Deep vein Thrombose DVT is the formation of a blood clot within a deep vein, Thrombose. Thrombose most commonly affects leg veins, such Thrombose the femoral vein, Thrombose.
Three factors are important in the Thrombose of a blood clot within a deep vein—these are the rate of blood flow, the thickness of the blood and qualities of the vessel wall. Classical signs of DVT include swellingpain and redness of the affected area, Thrombose.
Paget-Schroetter disease is the obstruction of an upper extremity vein such as the axillary vein or subclavian vein by a Thrombose. The condition usually comes to light after vigorous exercise and usually presents in younger, otherwise healthy people.
Men are affected more Thrombose women. Budd-Chiari syndrome is the blockage of a hepatic vein or of the hepatic part of the inferior vena cava, Thrombose.
This form of thrombosis presents with abdominal painThrombose, ascites and enlarged liver. Treatment varies between therapy and surgical intervention by the use of shunts. Portal vein thrombosis affects the hepatic portal veinThrombose can lead to portal hypertension and reduction of the blood supply to the liver.
Renal vein thrombosis is the obstruction of the renal vein by a thrombus. This tends to lead to reduced drainage from the kidney. Cerebral venous sinus thrombosis CVST is a rare form of stroke which results from the blockage of the dural venous sinuses by a thrombus. Symptoms may include headache Thrombose, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body and seizures, Thrombose.
The majority of persons affected make a full recovery. The mortality rate is 4. Jugular vein thrombosis is a condition that may occur due to infection, intravenous drug use or malignancy. Jugular vein thrombosis can have a varying list of complications, including: Though characterized by a sharp pain at the site of the Thrombose, it can prove difficult to diagnose, because it can occur at random.
Cavernous sinus thrombosis is a specialised form of cerebral venous sinus thrombosis, where there is thrombosis of the cavernous sinus of the basal skull dura, Thrombose, due to the retrograde spread of infection and endothelial Thrombose from the danger triangle of the face.
The facial veins in this area anastomose with the superior and inferior ophthalmic veins of the orbit, Thrombose, which drain directly posteriorly into the cavernous sinus through the superior orbital fissure, Thrombose. Staphyloccoal or Streptococcal infections of the face, for example nasal or upper lip pustules may thus spread Thrombose into the cavernous sinus, causing stroke-like symptoms of double visionsquintas well as Thrombose of infection to cause meningitis.
Arterial thrombosis is the formation of a thrombus within an artery, Thrombose. In most cases, arterial thrombosis follows rupture of atheroma a fat-rich deposit in the Beine geschälte Varizen vessel wall Thrombose, and is therefore referred to as atherothrombosis, Thrombose.
Arterial embolism occurs when clots then migrate downstream, Thrombose, and can Thrombose any organ, Thrombose. Alternatively, arterial occlusion occurs Venen Medikamente für Krampfadern a consequence of embolism of blood clots originating from the heart "cardiogenic" Thrombose. The most common cause is atrial fibrillationwhich causes a blood stasis within the atria with easy thrombus formation, Thrombose, but blood clots can develop inside the heart for other reasons too.
A stroke is the rapid decline of brain function due to a disturbance in the supply of blood to the brain, Thrombose. This can be due to ischemiaThrombose, thrombus, embolus a Thrombose particle or hemorrhage a bleed. In thrombotic stroke, a thrombus blood clot usually forms around atherosclerotic plaques. Since blockage of the artery is gradual, Thrombose, onset of symptomatic thrombotic strokes is slower, Thrombose.
Thrombotic stroke can be divided into two categories—large vessel disease and small vessel disease. The former affects vessels such as the internal carotidsvertebral Thrombose the circle of Willis. The latter Thrombose affect smaller vessels such as the branches of the circle of Willis. Myocardial infarction MI or heart attack, Thrombose, is caused by ischemia, Thrombose, restriction in the Diagnose und Behandlung von Krampfadern der unteren Extremitäten supplyThrombose due to the obstruction of a coronary artery by a thrombus.
This restriction gives an insufficient supply of Thrombose to the heart muscle which then results in tissue death, infarction, Thrombose. A lesion is then formed which is the infarct, Thrombose.
MI can quickly become fatal if emergency medical treatment is not received promptly. If diagnosed within 12 hours of the initial episode attack then thrombolytic therapy is initiated, Thrombose.
An arterial thrombus or embolus can also form in the limbs, Thrombose can lead to acute limb ischemia. Hepatic artery thrombosis usually occurs as a devastating Thrombose after liver transplantation, Thrombose. Thrombosis prevention is initiated with assessing the risk for its development, Thrombose.
Some people have a higher risk of developing thrombosis and its possible development into thromboembolism. The main causes of thrombosis are given in Virchow's triad which lists thrombophiliaendothelial cell Thrombose, and disturbed blood flow, Thrombose.
Hypercoagulability or thrombophiliais caused by, Thrombose, for example, Thrombose, genetic deficiencies or autoimmune disorders. Recent studies indicate that white blood cells play a pivotal role in deep vein thrombosis, Thrombose, mediating numerous pro-thrombotic actions. Any inflammatory process, Thrombose, such as trauma, Thrombose, surgery or infection, can cause damage to the endothelial lining of the vessel's wall, Thrombose.
The main mechanism is exposure of tissue factor to the blood coagulation system, Thrombose. Endothelial injury is almost invariably involved in the formation of thrombi in arteries, as high rates of blood flow normally hinder clot formation. In addition, Thrombose, arterial and cardiac clots are normally rich in platelets—which are required for clot formation in areas under high stress due to blood flow. Causes of disturbed blood flow include stagnation of blood flow past the point of injury, Thrombose, or venous stasis which may occur in heart failure or after long periods of sedentary behaviour, such as sitting on a long airplane flight.
Also, atrial fibrillationcauses stagnant blood in the left atrium LAor left atrial appendage LAAThrombose, and can lead to a thromboembolism.
Fibrinolysis is the physiological breakdown of blood clots Thrombose enzymes such as plasmin. For an occlusive thrombus defined as thrombosis within a small vessel that leads to complete occlusionwound healing will reorganise the occlusive thrombus into collagenous scar tissue, where the scar tissue will either permanently obstruct the vessel, or contract down with myofibroblastic activity to unblock the lumen. For a mural thrombus defined as a thrombus in Thrombose large vessel that restricts the blood flow but does not occlude completelyThrombose, histological reorganisation of the thrombus does not occur via the classic wound healing mechanism, Thrombose.
Instead, the platelet-derived growth factor degranulated by the clotted platelets will attract a layer of smooth muscle cells to cover the Thrombose, and this layer of mural smooth muscle will be vascularised by the blood inside the vessel lumen rather than by the vasa vasorum.
A venous thrombus may or may not be ischaemic, since veins distribute deoxygenated blood that is less vital for cellular metabolism. Nevertheless, non-ischaemic venous thrombosis may still be problematic, Thrombose, due to the swelling caused by Thrombose to venous drainage, Thrombose. In deep vein thrombosis Thrombose manifests as Thrombose, redness, and swelling; in retinal vein occlusion this may result Thrombose macular oedema and visual acuity impairment, which if severe enough can lead to blindness.
A thrombus Thrombose become detached and Thrombose circulation as an embolusThrombose, finally lodging in and Thrombose obstructing a blood vessel, which unless treated very quickly will lead to tissue necrosis an Krampfadern fällt mit in the area past the occlusion.
Venous thrombosis can lead to pulmonary embolism when the migrated Aerobic Varizen becomes lodged in the lung. In people with a "shunt" a connection between the pulmonary and systemic circulationeither in the heart or in the lung, Thrombose, a venous clot can also end up in the arteries and cause arterial embolism. Arterial embolism can lead to obstruction of blood flow through the blood vessel that is obstructed by it, and lack of oxygen and nutrients ischemia of the downstream tissue.
The tissue can become irreversibly damaged, Thrombose, a process known as necrosis. This can affect any organ; for instance, arterial embolism of the brain is one of the cause of stroke. The use of heparin following surgery is common if there are no issues with bleeding. Generally, a risk-benefit analysis is Thrombose, as all anticoagulants lead to an increased risk of Thrombose. In patients admitted for surgery, graded compression stockings are widely used, and in severe illness, prolonged immobility and in all orthopedic ThromboseThrombose, professional guidelines recommend low molecular weight Thrombose LMWH administration, Thrombose, mechanical calf compression or if all else is contraindicated and the patient has recently suffered deep vein thrombosis the insertion of a vena cava filter, Thrombose.
The treatment for thrombosis Thrombose on whether it is in a vein or an artery, the impact on the person, and the risk of complications from treatment. Warfarin and vitamin K antagonists are anticoagulants that can be taken orally to reduce thromboembolic occurrence. Where a more effective response is required, heparin can be given by injection concomitantly. As Thrombose side effect of any anticoagulant, the risk of bleeding is increased, Thrombose, so the international normalized ratio of blood is monitored.
Self-monitoring and self-management are safe options for competent patients, though their practice varies, Thrombose. Thrombolysis is Thrombose pharmacological destruction of blood clots by administering thrombolytic drugs including recombitant tissue plasminogen activatorThrombose, which enhances the normal destruction of blood clots by Varizen Sterne und wie sie behandeln body's enzymes.
This carries an increased risk of bleeding so is generally only used for specific situations such as severe stroke or a massive pulmonary embolism. Arterial thrombosis may require surgery if it causes acute limb ischemia. Mechanical clot retrieval and catheter-guided thrombolysis are used in certain situations.
Arterial thrombosis is platelet-rich, and inhibition of platelet aggregation with antiplatelet drugs such as aspirin may reduce the risk of recurrence or progression.
