INFLUENCE OF COMPLETE REVASCULARIZATION ON CHRONIC MESENTERIC ISCHEMIA

Complete revascularization for chronic intestinal ischemia is controversial. Fifty-eight patients (119 arteries) underwent mesenteric revascularization between 1981 and 1988. There were 46 women and 12 men (mean age: 63 years). Sixty percent of patients had three-vessel disease. Twenty-one patients underwent concomitant aortic reconstruction. Operative mortality was 10%. Four of the six deaths occurred in patients undergoing aortic surgery. Late graft failure occurred in five patients (10%). Five-year survival for patients with three-vessel involvement who underwent three-vessel repair was 73%, compared with 57% for two-vessel repair and 0% for one-vessel repair (p = NS). Similarly, graft patency in patients with three-vessel disease was highest in those patients who had complete revascularization (90%, 54%, and 0%, respectively) (p = NS). We conclude that in graft patency and survival in patients with three-vessel disease was most frequent with complete revascularization. Diseased inferior mesenteric arteries should be repaired if feasible. Concomitant aortic operations should be avoided if possible.
