AbstractA case of recurrent nonocclusive mesenteric ischemia in a patient with isolated internal iliac artery aneurysm penetrating the sigmoid colon is described. On the day after the aneurysm and the sigmoid colon had been resected, the patient developed necrosis of the left hemicolon. Fourteen and nineteen days after left hemicolectomy, massive intestinal bleedings occurred, requiring ileectomy. On the basis of operative findings of good pulsation of visceral arterial branches; angiography showing patent mesenteric vessels with some spasms; and pathological findings suggesting mesenteric ischemia, these ischemic events were diagnosed as nonocclusive mesenteric ischemia. Low-output syndrome induced by massive intestinal bleeding and atrial fibrillation and sepsis were responsible for the establishment of the nonocclusive mesenteric ischemia. Development of disseminated intravascular coagulation and continuous administration of diuretics for acute renal failure seemed to have further perturbed the mesenteric circulation. The patient died of subsequent multiple organ failure 4 months after the first operation. We should pay more attention to nonocclusive mesenteric ischemia in patients with mesenteric ischemia, and strict circulatory management during the perioperative period is essential in these patients.
