Although intestinal infarction is often the result of a sudden massive occlusion of the superior mesenteric artery or vein, it also sometimes is caused by nonocclusive vascular insufficiency of the intestine secondary to a low cardiac output state. Such patients should be managed by vigorously treating the cause of the low cardiac output rather than undertaking resection of the bowel, which is seldom successful because the circulation is insufficient to permit primary healing.
