title: Two cases of rectal carcinoma associating aorto-iliac occlusive disease.
abstract: Two cases of rectal carcinoma associating aorto-iliac occlusive disease are presented. These two cases had complete obstruction of the affected vessels, but many collateral pathways from the aorta to the legs had developed, mainly through the superior rectal artery or parietal vessels. Changes in blood flow to the legs, following the radical operation for rectal carcinoma, were examined by both preoperative angiography and perioperative Doppler flow meter. Vascular reconstruction was carried out in one case prior to resection of the rectum, in order to prevent the ischemic legs from becoming worse, or necrotic. The indications for supportive vascular surgery in the case of rectal carcinoma with aorto-iliac occlusive disease are discussed herein.
