Successful Treatment of Right Internal Iliac Artery Aneurysm Rupture with Arterio-rectal Fistula

Abstract

Arterio-enteric fistula to the lower gastrointestinal tract is a rare disease and considered to be poor prognosis. Although endovascular treatment for the disease has been reported, control of infection is a severe problem especially in the lower gastrointestinal fistula. An 88-year-old man presented with rectal bleeding. Rupture of the right internal iliac artery aneurysm was detected on CT. Emergency operation with aneurysm excision and colostomy was performed. The postoperative course was favorable. He was discharged on postoperative day 32.
