Abstract
We report a case with postoperative superior mesenteric arteriovenous fistula. A 64-year-old-woman who had undergone ileocecal resection for ileocecal invagination 2 years previously was admitted to the other hospital with diarrhea. Abdominal examination revealed a bruit in the right lower quadrant with a postoperative scar in the lower midline. Computed tomography demonstrated dilated superior mesenteric artery. Selective superior mesenteric arteriography revealed dilated superior mesenteric artery leading to an arteriovenous fistula with rapid filling of the superior mesenteric vein and resection of the fistula was performed. Iatrogenic mesenteric arteriovenous fistula is uncommon and surgery performed before the development of associated portal hypertension. A review of the literature follows the report of this case.
