RESUMEN
Superior mesenteric arteriovenous fistula is an extremely rare vascular malformation with most cases occurring following abdominal trauma or surgery. They are often asymptomatic or present with various abdominal symptoms with or without features of portal hypertension. A 30-year-old man developed fistulising of the superior mesenteric artery into the superior mesenteric vein following bowel resection surgery for an acquired midgut volvulus. Although endovascular management remains the treatment of choice in such cases due to increased morbidity of a repeat abdominal surgery, definite risks remain, such as coil migration, which happened in this case. The open surgical approach remains the only option in such instances.
