	Thrombosis - Wikipedia, the free encyclopedia
		Thrombosis is the formation of a clot or thrombus inside a blood vessel, obstructing the flow of blood through the circulatory system.
		Thromboembolism is a general term describing both thrombosis and its main complication: dislodgement of a clot and embolisation.
		The formation of a thrombus is usually caused by an injury to the vessel's wall, either by trauma or infection, and by the slowing or stagnation of blood flow past the point of injury.

	[No title]
		Thrombosis means the clotting of blood within an artery or a vein.
		When thrombosis affects important arteries, such as the coronary arteries (causing a heart attack) or the arteries supplying the brain with blood (causing a stroke), it is a major cause of death and serious illness.
		Thrombosis of arteries supplying the legs leads to pain on using the leg (or even when at rest if the thrombosis is severe).

		The factor V Leiden mutation is involved in 20 to 40 percent of venous thrombosis cases and is suspected in individuals who have a medical history of venous thrombosis or in families with a high incidence of venous thrombosis.
		Thrombosis occurs when clots obstruct veins (blood vessels that carry blood from the body back into the heart) or arteries (blood vessels that carry oxygenated blood away from the heart to the body).
		Arterial thrombosis may be the result of arteriosclerosis (hardening of the arteries where fatty or calcium deposits cause the arterial walls to thicken) of blood vessels (clots form on abnormal blood vessel surfaces).

	MSRGSNet/Genetic Drift/Venous Thrombosis and the Factor V (Leiden) Mutation
		Venous thrombosis is a multifactorial condition caused by a combination of genetic, aquired or environmental influences.
		Clinical presentation of thrombosis in affected individuals is similar for all the disorders and the thrombosis is often recurrent.
		Thrombosis incidence is increased 7-fold in heterozygotes and 80-fold in homozygotes compared to incidence in people without the mutation.

	Deep Vein Thrombosis: Venous Disorders: Merck Manual Home Edition
		Thrombophlebitis is a disorder in which the formation of blood clots (thrombosis) and inflammation of the vein (phlebitis) occur together.
		For example, deep vein thrombosis may develop in people who have had a heart attack and lie in hospital beds for several days without sufficiently moving their legs or in people whose legs and lower body are paralyzed (paraplegics).
		When deep vein thrombosis blocks blood flow in a large leg vein, the calf swells and may be painful, tender to the touch, and warm.

	Venous thrombosis - Wikipedia, the free encyclopedia
		A venous thrombosis is a blood clot that forms within a vein.
		Thrombosis is a specific medical term for a blood clot that remains in the place where it formed.
		Superficial venous thromboses can cause discomfort but generally do not cause serious consequences, unlike the deep venous thromboses (DVTs) that form in the deep veins of the legs or in the pelvic veins.

	Thrombosis Prevention: Online Reference For Health Concerns
		Thrombosis has been described as coagulation occurring in the wrong place or at the wrong time.
		The end result of thrombosis is an obstruction of the blood flow.
		Although anticoagulants (such as Coumadin and heparin) are the conventional treatment of choice for thrombosis prevention, thrombi which arise solely from hypercoagulability are considered to be uncommon.

	Renal vein thrombosis
		Renal vein thrombosis develops when a blood clot forms in the renal vein, which carries blood from the kidneys back to the heart.
		In adults, renal vein thrombosis can be caused by injury to the abdomen or back, as a result of malignant kidney tumors growing into the renal vein, or as a result of kidney diseases that cause degenerative changes in the cells of the renal tubules (nephrotic syndrome).
		Death from renal vein thrombosis is rare, and is often caused by the blood clot detaching and lodging in the heart or lungs.

		On average, deep vein thrombosis is fairly rare and affects about 1 person in 1700.
		The incidence of deep vein thrombosis appears to be increased two - four folds in HRT users, according to John Studd, the risk seems to be higher when treatment is started and reduces significantly in long term users.
		Any woman that already has a history of deep vein thrombosis or pulmonary embolism should avoid taking HRT, unless the throbosis was as a result of surgery, accident, pregnancy or childbirth in which case there should not be an increased risk.

		A related condition is thrombosis of the subclavian vein that is induced by the presence of indwelling catheters.
		Among patients with effort-induced thrombosis with subclavian vein stenosis, the thrombosis occurs in the dominant arm in 80% of cases.
		In the 1960s, the term effort-induced thrombosis was used to describe this disease to acknowledge that it often follows unusually strenuous use of the arm or shoulder on the affected side.

		Deep vein thrombosis (DVT) is a blood clot in a major vein, usually in the legs and/or pelvis.
		Deep vein thrombosis is a major complication in patients who have had orthopedic surgery or pelvic, abdominal, or thoracic surgery.
		Deep vein thrombosis is caused by blood clots in blood vessels that form in veins where blood flow is sluggish or has been disturbed, in pockets in the calf's deep veins, or in veins that have been traumatized.

		Armand Trousseau observed that cancer appeared to predispose the blood to "spontaneous coagulation." Clinically detectable thrombosis is present in 15% of all cancer patients, and postmortem evidence suggests prevalence is actually much higher.
		Cancer patients are at least twice as likely to develop postoperative thrombosis than their counterparts without cancer undergoing the same surgical procedure and to experience a recurrent thromboembolic event after an initial episode.
		Studies indicate that thrombosis is one of the most frequent complications and the second leading cause of death in patients with known cases of cancer.

	Venous Thrombosis
		It is estimated that venous thrombosis and pulmonary embolism are associated with 300,000 to 600,000 hospitalizations a year and that as many as 50,000 individuals die each year as a result of pulmonary embolism.
		Both venous thrombosis and pulmonary embolism are often silent and difficult to detect by clinical examination.
		The largest pool of data has been obtained in studies of patients over the age of 40 undergoing general surgical procedures, where the average incidence of deep venous thrombosis in control patients is 25 percent by fibrinogen scanning and 19 percent by venography.

	Thrombosis (Site not responding. Last check: 2007-11-06)
		A thrombus is a blood clot which forms on the roughened or inflamed wall of a vein or artery; sluggish circulation and high blood lipid levels (see Atherosclerosis) encourage this to happen.
		A blood clot, or fragments of a blood clot, can also be swept into general circulation and lodge in a distant blood vessel (embolism); if heart, brain, or lungs are affected the result will be a Heart attack, a Stroke, or pulmonary embolism.
		Thrombosis is conventionally treated with anticoagulants, which dissolve clots.

		This means that the risk of having a venous thrombosis is twice that of someone without the condition.
		Prothrombin 20210 does not increase the risk of arterial thrombosis, so there is no increased risk of heart attacks or strokes.
		As well as an increased risk of venous thrombosis, women with Prothrombin 20210 may have a slightly higher risk of placental problems during pregnancy.

	UpToDate Patient information: Venous thrombosis
		Some types of inherited thrombophilia, such as deficiencies of antithrombin, protein C or protein S, usually are associated with venous thrombosis in people less than 50 years of age, while others, such as factor V Leiden or the prothrombin gene mutation, can predispose to a first thrombosis in all age groups.
		Other goals of treatment include prevention of further clot extension, prevention of a recurrence of thrombosis, and the prevention of complications, such as the postphlebitic syndrome and chronic high blood pressure in the vessels between the heart and lungs (pulmonary hypertension).
		Not all patients with venous thrombosis are alike, and it is important that your situation is evaluated by someone who knows you as a whole person.
