Aortoiliac endarterectomy: an 11-year review.
Fifty-seven patients underwent aortoiliac endarterectomy over an 11-year period, the majority (86 per cent) for disabling claudication. No patient died within 30 days of surgery, but nine patients suffered significant complications. The cumulative survival rate was 98 per cent at 1 year, and was 94 and 78 per cent at 5 and 10 years respectively. Cumulative operated segment patency rates were 92 per cent at 5 years and 68 per cent at 10 years. There was no significant difference in survival rates between patients who smoked after surgery and those who did not, but smokers had significantly worse rates for cumulative patency, limb failure and symptom status than non-smokers. Twenty-seven patients developed worsening symptoms during follow-up and 24 patients required secondary vascular intervention. Fourteen patients subsequently required aortofemoral bypass and the largest single cause of operated segment failure was recurrent disease in the external iliac artery. Our evidence suggests that, while aortoiliac endarterectomy should be considered in young patients with localized disease not involving the external iliac artery, those who do not fit these criteria should be considered for primary aortofemoral bypass. Regardless of the choice of operation, the chance of success is jeopardized if the patient continues to smoke.
