Iatrogenic superior mesenteric arteriovenous fistulas are rare in Japan. A nonsymptomatic superior mesenteric arteriovenous fistula, which was accidentally detected during a clinical examination for a pulsatile abdominal tumor, is reported. There was a history of small bowel resection for intestinal obstruction following appendectomy seven years before. Following successful resection of the arteriovenous fistula, aneurysmectomy and grafting were performed. After surgery continuous murmur disappeared and abdominal CT and angiography revealed decreased diameters of the superior mesenteric artery and portal vein. This cause might lie in the mass ligation of the blood vessels at the small bowel resection about seven years before. Postoperative course was uneventful.
