| blood clot | <haematology> The conversion of blood from a liquid form to solid through the process of coagulation. A thrombus is a clot which forms inside of a blood vessel. If that clot moves inside the vessel it is referred to as an embolus (embolism). The presence of atherosclerotic plaque lining blood vessel walls is a significant stimulus for clot formation.

|---|---|
| passive clot | A clot formed in an aneurysmal sac consequent to the cessation or slowing of circulation through the aneurysm. (05 Mar 2000) |
| medication, clot-dissolving | Drugs used to dissolve blood clots. Agents such as plasminogen-activator (t-pa) and streptokinase that are effective in dissolving clots and re-opening arteries. Used, for example, in the treatment of heart attacks. Clot-dissolvers are also called thrombolytic agents. (12 Dec 1998) |
| chicken fat clot | Clot formed in vitro or postmortem from leukocytes and plasma of sedimented blood. (05 Mar 2000) |
| clot | 1. To coagulate, said especially of blood. 2. A soft, nonrigid, insoluble mass formed when a liquid (e.g., blood or lymph) gels. Origin: O.E. Klott, lump (05 Mar 2000) |
| clot-dissolving medications | Agents such as plasminogen-activator (t-PA) and streptokinase that are effective in dissolving clots and re-opening arteries. Used, for example, in the treatment of heart attacks. Also called thrombolytic agents. (12 Dec 1998) |
| clot retraction | Retraction of a clot resulting from contraction of platelet pseudopods attached to fibrin strands that is dependent on the contractile protein thrombosthenin. Used as a measure of platelet function. (12 Dec 1998) |
| clot retraction time | The time required for a blood clot to separate from the tube wall and express serum, usually completed in 18 to 24 hours, but retarded or absent in persons with thrombocytopenic purpura. (05 Mar 2000) |
| mucin clot test | A test that reflects the polymerization of synovial fluid hyaluronate; a few drops of synovial fluid added to acetic acid form a clot; poor clot formation occurs in a variety of inflammatory conditions including septic arthritis, gouty arthritis, and rheumatoid arthritis. Synonym: Ropes test. (05 Mar 2000) |
| postmortem clot | A clot formed in the heart or great vessels after death. (05 Mar 2000) |
| currant jelly clot | A jelly-like mass of red blood cells and fibrin formed by the in vitro or postmortem clotting of whole or sedimented blood. (05 Mar 2000) |
| Schede's clot | Filling of the defect in bone, after removal of a sequestrum or scraping away carious material, by allowing the cavity to fill with blood which may become organised (Schede's clot). (05 Mar 2000) |
| euglobulin clot lysis time | A measure of the ability of plasminogen activators and plasmin to lyse a clot; normally, clot lysis is determined by the balance of factors which activate fibrinolysis (plasminogen activators and plasmin) and those which inhibit lysis; in certain conditions (e.g., carcinoma or hepatic insufficiency) activating factors predominate and can be measured by noting the time it takes the euglobulin fraction of plasma (excluding inhibitors of fibrinolysis) to clot. (05 Mar 2000) |
| laminated clot | A clot formed in a succession of layers such as occurs in the natural course of an aneurysm. (05 Mar 2000) |
