Venous thromboembolism, ie, venous thrombosis and pulmonary embolism, represents a serious and potentially fatal complication for many sick, hospitalized patients, especially those who are bedridden for extended periods of time. The clot itself is termed a thrombus. It may occur in all venous sections of the body and in the extremities; the superficial as well as the deep venous system may be involved.

Pathogenesis of (athero)thrombosis in Behçet’s syndrome The pathophysiology of thrombosis in Behçet’ssyndrome (BS) is not well known, but systemic inflammation seems to play a major role whereas other thrombophilic factors are less relevant [13].
