title: [Primary abdominal aortoduodenal fistula: a case report].
abstract: Abdominal aortoenteric fistula (AAEF) is a rare but life-threatening complication of abdominal aortic aneurysms, and is also an uncommon cause of gastrointestinal hemorrhage. We report a case of primary abdominal aortoduodenal fistula in a 74-year-old male patient, whose main clinical manifestations were abdominal pain, hematochezia, and hematemesis. Colonoscopy, abdominal enhanced computed tomography (CT) and three-dimensional reconstruction angiography confirmed the diagnosis. The patient recovered well after emergent surgical management.
