[A case of traumatic inferior mesenteric arteriovenous fistula].

Inferior mesenteric arteriovenous fistula is rare and may be congenital or acquired. Affected patients present with abdominal pain, mass, or manifestations of portal hypertension and bowel ischemia. Until now, inferior mesenteric arteriovenous fistula due to trauma has not been reported. Herein, we report a case of a 53-year-old woman who had inferior mesenteric arteriovenous fistula considered to have originated from remote blunt trauma that was successfully treated by surgical resection of only the arteriovenous fistula without colectomy. To our knowledge, this is the first case of traumatic inferior mesenteric arteriovenous fistula.
