Transcatheter arterial occlusion was performed in five patients with recurrent rectosigmoidal bleeding. Four had malignant neoplasms, and the fifth, an arteriovenous malformation. The superior hemorrhoidal artery was embolized in two patients, the inferior mesenteric artery in two, and the left internal iliac artery in one patient. In four patients, immediate and complete control of rectal bleeding was achieved, and gradual control was accomplished in the fifth patient. Left lower quadrant pain and fever developed in three patients. The possibility of rectosigmoidal bleeding from the internal iliac artery is stressed.
对5例复发性直肠乙状结肠出血患者实施了经导管动脉闭塞术。其中4例患有恶性肿瘤，第5例为动静脉畸形。2例患者栓塞了痔上动脉，2例栓塞了肠系膜下动脉，1例栓塞了左髂内动脉。4例患者的直肠出血得到立即和完全控制，第5例患者出血逐渐得到控制。3例患者出现左下腹疼痛和发热。强调了髂内动脉导致直肠乙状结肠出血的可能性。
