Fenestration of the common iliac vein: an unusual cause of deep venous thrombus

Abstract

Iliac venous anomalies are reported in 20.9% of patients; however, fenestration or bifurcation of the common iliac vein only accounts for ~0.4% of patients [ 1]. Herein, we present and discuss the rare case of an iliofemoral deep vein thrombosis precipitated by a fenestrated left common iliac vein.
