title: Surgical treatment of nonocclusive mesenteric infarction.
abstract: Two cases of nonocclusive mesenteric vascular disease associated with stenosis of the superior mesenteric artery are described. In one patient with congestive heart failure and atrial fibrillation treated with digitalis, the first episode after a bout of sepsis was treated supportively, but a stricture of ileum secondary to full thickness intestinal infarction resulted. His second episode required emergency ileal resection for perforation. The superior mesenteric artery was subsequently reconstructed with an aortomesenteric bypass. The second patient had segmental intestinal necrosis occurring in association with superior mesenteric artery narrowing without total occlusion. These cases emphasize the importance of awareness of nonocclusive mesenteric vascular disease occurring in individuals with narrowing of the mesenteric arteries. A variety of modes of presentation are suggested. Arteriography is essential for diagnosis and, in selected cases, for therapy.
