Arterio-appendiceal fistula after arterial reconstruction with synthetic graft

A patient who 5 years previously had an aortoiliac reconstruction with a dacron graft developed intestinal bleeding. At laparotomy this was found to be due to a fistula between a pseudoaneurysm at the right iliac artery anastomosis and the appendix. Resection of the aneurysm and adjacent parts of artery and graft with additional appendectomy prevented further intestinal bleeding. A search of the literature produced only one previously reported case similar to this.
