We report two cases of acute superior mesenteric artery occlusion improved by Interventional Radiology (IVR). Case 1 was a 70-year-old mas. The chief complaint was right lower addominal pain. Eleven hours after onset of this complaint, abdominal angiography was conducted to expand the occlusive artery with a balloon caterther. Two days later, laparotomy was performed, because inflammatory signs reappeared. Necrosis of a 20 cm segment of the small intestine was confirmed, and a partial resection of small intestine was carried out. Case 2 was a 50-year-old man. While undergoing treatment for acute artery occlusion of the lef leg, he experienced pain around the navel. Forty-eight hours after onset, abdominal CT and angiography were performed, and thrombolysis with urokinase for the occlusive artery was conducted simultaneously. Next day when angiography was performed again, the presence of the poorly dye-stained lesion was confirmed. So experimental laparotomy was carried out and no necrosis of the intestine was detected. IVR was useful for diagnosis and therapy in these cases.
