|---|---|
| purpura, thrombotic thrombocytopenic | A disease characterised by thrombocytopenia, haemolytic anaemia, bizarre neurological manifestations, azotemia, fever, and thromboses in terminal arterioles and capillaries. (12 Dec 1998) |
| nonbacterial thrombotic endocarditis | Verrucous endocardial lesions occurring in the terminal stages of many chronic infectious and wasting diseases. Synonym: abacterial thrombotic endocarditis, cachectic endocarditis, terminal endocarditis, thromboendocarditis. (05 Mar 2000) |
| thrombotic | Relating to, caused by, or characterised by thrombosis. (05 Mar 2000) |
| thrombotic disease due to protein c deficiency | Protein C is a protein in plasma that enters into the cascade of biochemical events leading to the formation of a clot. Deficiency of protein c results in thrombotic (clotting) disease and excess platelets with recurrent thrombophlebitis (inflammation of the vein that occurs when a clot forms). The clot can break loose and travel through the blood stream (thromboembolism) to the lungs causing a pulmonary embolism, brain causing a stroke (cerebrovascular accident), heart causing an early heart attack, skin causing what in the newborn is called neonatal purpura fulminans, the adrenal gland causing haemorrhage with abdominal pain, abnormally low blood pressure (hypotension), and salt loss. Protein c deficiency is due to possession of one gene (heterozygosity) in chromosome band 2q13-14. The possession of two such genes (homozygosity) is usually lethal. (12 Dec 1998) |
| thrombotic gangrene | Gangrene due to occlusion of an artery by a thrombus. (05 Mar 2000) |
| thrombotic hydrocephalus | Increase in cerebrospinal fluid and of intracranial pressure following thrombosis of the cerebral veins or sinuses; caused by septic infection, dehydration, tuberculosis, typhoid, leukaemia, and other conditions. (05 Mar 2000) |
| thrombotic infarct | An infarct caused by a thrombus. (05 Mar 2000) |
| thrombotic microangiopathy | Thrombosis within small blood vessels, as in thrombotic thrombocytopenic purpura. (05 Mar 2000) |
| thrombotic phlegmasia | An extreme edematous swelling of the leg following childbirth, due to thrombosis of the iliofemoral veins. Synonym: leukophlegmasia dolens, milk leg, puerperal phlebitis, thrombotic phlegmasia, white leg. (05 Mar 2000) |
| thrombotic thrombocytopenic purpura | A rapidly fatal or occasionally protracted disease with varied symptoms in addition to purpura, including signs of central nervous system involvement, due to formation of fibrin or platelet thrombi in arterioles and capillaries in many organs. Synonym: Moschcowitz' disease. (05 Mar 2000) |
| Alfven velocity | <physics, radiobiology> Phase velocity of the Alfven wave, equal to the speed of light divided by the square root of (1 plus the ratio of the plasma frequency to the cyclotron frequency for a given species). Va = c / SQRT(1 + plasma frequency / cyclotron frequency) (13 Nov 1997) |
| blood flow velocity | A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. (12 Dec 1998) |
| velocity | The time rate of motion, the distance traveled divided by the time required to travel that distance. (09 Oct 1997) |
| velocity coefficient | The rate of transformation of a unit mass of substance in a chemical reaction. (05 Mar 2000) |
