Endovascular Repair of Iatrogenic Superior Mesenteric Arteriovenous Fistula

Abstract 

Arteriovenous fistulas between the superior mesenteric artery and vein are extremely rare and often a late complication of bowel resection. We report a case of a 42-year-old male, who presented with abdominal pain and dyspnoea 9 years after ileo-caecal resection. A superior mesenteric arteriovenous fistula was detected and treated endovascularly with an Amplatzer Vascular Plug, thereby reducing the cardiac output and flow in the superficial mesenteric artery by 1.1lmin⁻¹. The patient had an uneventful recovery.
