An unusual duplication of the inferior vena cava in a patient with endovascular repair for abdominal aortic aneurysm.

A 66-year-old Caucasian male, with sensation of abdominal pulsation was admitted to our hospital. In multidetector 64-row computed tomography (CT) angiography, an abdominal aortic aneurysm was observed. Endovascular aortic repair was performed. Control CT confirmed prosperity with stent graft fixation and absence of any vascular complications. Investigation also showed asymmetrical duplication of the inferior vena cava (IVC). Right (RIVC) and left (LIVC) inferior vena cava arose from the confluence of the right and left iliac veins. The LIVC continued as left renal vein.
