    Abstract:
    An interesting and rare case of traumatic superior mesenteric artery-to-portal vein arteriovenous fistula is presented. Initial operative control of the bleeding superior mesenteric artery injury required ligation of the superior mesenteric artery at its origin to prevent exsanguination in an extremely unstable patient with multiple injuries. Early postoperative visceral arteriography documented ligation of the superior mesenteric artery with a proximal superior mesenteric artery-to-portal vein arteriovenous fistula. Percutaneous catheter embolization of the arteriovenous fistula was undertaken successfully at this time. Superior mesenteric artery ligation was surprisingly well tolerated. Major arterioportal fistulas require treatment to prevent long-term complications of intestinal ischemia, portal hypertension, and cirrhosis. Although traditional treatment involves ligation of the arteriovenous fistula and arterial bypass, percutaneous embolization is becoming a viable alternative. Arteriography remains the cornerstone of diagnosis and treatment planning.
