Early complications directly related to the vascular procedure and which required urgent reoperation occurred in 8% of 628 patients undergoing operations on the arteries of the neck, extremities, and abdomen. The indications for reoperation in this group of 50 patients were recurrent vascular occlusion (29), hemorrhage (13), and bowel ischemia (8). The mortality for those patients not requiring reoperation was 7.5%, but rose to 32% for those patients who did require reoperation. While the risk attending reoperation for abdominal bleeding or bowel ischemia is high (71% and 75%, respectively), these complications are fatal if untreated. Reoperation for occlusion of arteries in the leg carried a low risk (5%), and successful results were obtained 68% of the time.
