 A 67-year-old woman consulted her previous doctor with a chief complaint of bloody stool. She was diagnosed with rectal cancer and referred to our department for surgical treatment. Computed tomography revealed concentric thickness of the rectosigmoid wall and the double inferior vena cava. The tumor was diagnosed as rectal cancer cT2N1bM0 cStageⅢa, and robot-assisted anterior resection was performed. We identified the double inferior vena cava during surgery. There were no massive bleeding necessitating blood transfusion or complications. Double inferior vena cava is a congenital venous anomaly with a reported incidence of 1.0%-3.0%. Most cases of double inferior vena cava are clinically silent and diagnosed incidentally. However, such venous anomalies can cause massive bleeding during abdominal surgery. The precise recognition of such anatomies is important to avoid fatal complications during surgery.
