title: A primary aorto-duodenal fistula associated with an inflammatory abdominal aortic aneurysm: a case report.
abstract: Primary aorto-enteric fistula (PAEF)is a serious complication of abdominal aortic aneurysm(AAA). We report a patient with PAEF associated with inflammatory AAA who underwent emergent surgery. A 52-year-old male presented with recurrent hematemesis. A computer tomography scan showed a sealed rupture of the AAA adjacent to the duodenum. At surgery, a coin-sized PAEF was noted. The aorta was replaced with a Dacron graft in situ . Histological examination revealed the characteristics of an inflammatory AAA. The postoperative course was uneventful, and there has been no evidence of infection during a follow-up period of 3 years. We discuss the etiologic and surgical considerations regarding this unusual entity.
