The pathogenesis and prophylaxis of venous thrombosis of the lower extremities remains cloaked in mystery, despite (perhaps because of) the many articles in our overburdened literature, like that of Husni et al (214:1456-1462, 1970). If the clot breaks loose and travels through the bloodstream, it is a thromboembolism.

Pathogenesis As per the current knowledge, the causes of thrombosis include vessel wall injury, abnormal changes in blood constituents, and venous stagnation. These grow by apposition (8 +C) to occlude more and larger ve­ nous vessel segments. 16 0 obj Although endothelial damage is speculated to be necessary for symptomatic thrombosis to occur, venous thrombosis may be associated with a deficiency in 1 of several anticoagulant factors.
