Abstract
- Iatrogenic superior mesenteric arteriovenous fistula is rare. We treated a patient with this problem 6 years after small bowel resection for intestinal obstruction. The symptoms and signs were those of intestinal ischaemia and portal hypertension with an abdominal bruit. Ultrasonography and enhanced computerized tomography of the abdomen suggested the presence of superior mesenteric arteriovenous fistula, with a dilated portal vein and a communication between the dilated superior mesenteric vein and its artery. The exact location of the fistula was then determined by selective superior mesenteric arteriography. The fistula was ligated in an emergency operation to prevent cardiac or renal failure and to relieve portal hypertension. Liver biopsy showed no cirrhotic changes, but fibrosis was seen around the portal veins. We describe here not only the diagnostic arteriographic findings of superior mesenteric arteriovenous fistula, but also the interesting and suggestive ultrasonographic and computed tomographic findings. Early correction of such fistulas is recommended to prevent cardiac or liver failure.
