Laparoscopic Resection of Rectal Cancer in a Patient with Double Inferior Vena Cava on Preoperative Computed Tomography—A Case Report—

Abstract

A 48-year-old woman came to our hospital complaining of bloody stools. Colonoscopic examination by a local doctor found rectal cancer at the rectosigmoid colon. On abdominal computed tomography (CT) in our hospital, the diagnosis was rectal cancer. In addition, 3D-CT angiography showed Type 2a double inferior vena cava (DIVC) with no interiliac communication. Laparoscopic anterior resection of rectal cancer was safely performed in a patient with DIVC. There are a few reports of colorectal cancer with DIVC. Since some patients with DIVC have multiple gonadal veins or ureter anomalies, the surgery needs to be performed carefully.
