Venous Thrombosis

Abstract

Certain pathological situations, usually several, interact to cause the development of a coagulum (thrombus) of clottable protein (fibrin) and cellular blood components within veins, which may cause damage by occluding the venous circulation locally, or by migration (embolization) elsewhere in the vascular tree. Treatment is usually by anticoagulation, which prevents further formation, relying on natural lysis to remove the fibrin.

Keywords: thrombus; pulmonary emboli; coagulation; anticoagulation; fibrinolysis; thrombophilia; thrombophlebitis
