Thrombophlebitis refers to inflammation of a vein associated with the formation of a blood clot. This may arise due to an interaction of endothelial injury, stasis of blood, and a hypercoagulable state. Risk factors include intravenous catheter placement, immobilization, malignancy, inherited prothrombotic condition (eg, factor V Leiden, antithrombin III deficiency), antiphospholipid antibody syndrome, and Behçet disease. One study found vascular involvement in 14% of patients with Behçet disease, most commonly manifesting as superficial vein thrombophlebitis or deep vein thrombosis. [9]
