AXILLOFEMORAL BYPASS AS A LIMB SALVAGE PROCEDURE IN HIGH-RISK PATIENTS WITH AORTOILIAC DISEASE

Thirty‐eight patients presenting with severe limb ischaemia and considered unfit for major aortic reconstruction underwent axillofemoral bypass as a limb salvage procedure. Four patients (11 per cent) died, including two who had presented with bilateral ischaemia secondary to acute aortic occlusion. The operative mortality rate for patients presenting with rest pain or ulceration/gangrene was 6 per cent. Cumulative 5‐year survival and limb salvage were 44 per cent and 86 per cent respectively. Graft occlusion was the principal cause of worsening symptoms during follow‐up (5‐year primary patency of 68 per cent) and accounted for all major amputations of the operated limb. Axillounifemoral grafts had a significantly worse 5‐year patency (50 per cent) than axillobifemoral grafts (80 per cent, P < 0·05) and three of five patients who developed worsening symptoms in the non‐operated limb died or required a major limb amputation as a consequence. Axillofemoral bypass is a valuable alternative to major aortic reconstruction in elderly patients and allows a greater proportion to be offered reconstruction than would otherwise be possible.
