Extended septic thrombophlebitis in a patient with duplicated inferior vena cava: case report and review of literature.

Duplication is one of the congenital abnormalities of the inferior vena cava (IVC) and is reported to be associated with deep venous thrombosis (DVT). We report a case who was admitted for carbamazepine-induced toxic epidermal necrolysis. The patient had persistent fever caused by septic thrombophlebitis extending from the left femoral vein to the duplicated left IVC. The fever and thrombosis resolved under combined treatment with antibiotics and anticoagulants, without further complication of symptomatic pulmonary embolism. This is the first case in patient with IVC duplication complicated by DVT induced by septic thrombophlebitis, which was not seen in the nine cases of IVC duplication reported previously.
