title: Operation for late complications of aortic grafts.
abstract: In a period of seven years, 120 revision operations were performed for complications occurring in 1,284 aortic bifurcation grafts. The reasons cited for operation were: graft limb occlusion or stenosis in 82 patients, false aneurysm in 28 and symptomatic disease distal to the graft in ten. Preferred operations were replacement of the graft and distal anastomosis for occlusion or complete reconstruction of the anastomosis with fresh graft material for a false aneurysm. The operative mortality rate was 1.6 per cent and three patients (2.5 per cent) underwent amputation after multiple procedures. This group of 120 patients with complications was compared with a random sample of 300 patients with aortic bifurcation grafts with no complications. In the group with complications, there were significantly fewer patients who underwent sympathectomy or profundaplasty and significantly more with an iliac rather than a femoral artery graft insertion. Those patients who had graft complications develop also had a significantly higher hematocrit level at the first procedure.
