A review of 155 extra-anatomic bypass grafts.
Extra-anatomic bypass grafting has been used as treatment for patients with aorto-iliac disease who were considered unfit for aortic surgery. Eighty five percent of the patients had ischaemic pain at rest or skin necrosis. One hundred and three femorofemoral (FF) grafts, 40 axillounifemoral and 12 axillobifemoral grafts were performed. Femoropopliteal extension grafts were performed in 39 cases. The three year cumulative graft patency rate was 69% for FF grafts and 48% for both types of axillofemoral (AF) graft, falling to 61% for FF grafts and 32% for AF grafts at five years. The long term patient survival rate was poor, particularly for AF grafts, 27% at five years, reflecting the poor general condition of these patients. In addition almost a quarter of AF grafts required declotting at some stage. However, worthwhile limb salvage rates were obtained with both types of grafts, 69% for FF and 72% for AF at three years and 61% for FF and 65% for AF at five years, suggesting that these grafts should be employed as a means of avoiding amputation in poor risk patients.
