We recently encountered a case of posttraumatic SMAVF(Superior mesenteric arteriovenous fistula), which hastreated by coil embolization. He had history of stab wound and emergent operation. Operative diagnosis was gastricperforation and mesenteric laceration which was simply repaired. After history of abdominal stab woung andoperation, he developed palpitation and thrill in left upper abdomen. Recentrly he have experienced syncope twice.On superior mesenteric arteriogram, early visualiation of superior mesenteric vein and portal vein was noted. Weembolized the SMAVF by using coils. Since coil embolization, palpitation and thrill disappreared.
