Coil Embolization of an Iatrogenic Arteriovenous Fistula between the Superior Mesenteric Artery and Vein: A Case Report

Superior mesenteric arteriovenous fistulae are rare. a 32-year-old woman presented with abdominal pain. the angiography showed that the superior mesenteric vein was aneurysmal. the patient underwent coil embolization, during which a balloon catheter was inflated before the fistula for the protection of coil migration with a high blood flow. after the balloon inflation, one 8-mm and two 7-mm coils were deployed at the fistula site. the final angiography showed successful embolization with no visualization of the fistula and the aneurysmal vein.
