We describe a case of fatal gastrointestinal bleeding probably caused by an aortoduodenal fistula following open surgical repair of an inflammatory abdominal aortic aneurysm (AAA) during postoperative steroid therapy. A 71-year old man underwent a graft replacement for an inflammatory AAA. Prolonged elevated C-reactive protein and newly emerged ascites after surgery were improved by oral administration of predonine. The steroid therapy had been continued until 5 months after surgery, when he suffered from fatal gastrointestinal bleeding. We speculated that the gastrointestinal bleeding was caused by an aortoduodenal fistula and discuss the etiology of this condition.
