Iliofemoral versus femorofemoral bypass: a 6-year audit.

Iliofemoral and femorofemoral crossover bypass operations performed over a 6-year period were reviewed. A total of 226 patients underwent 231 operations from 1984 to 1990. Seventy-two patients had 75 iliofemoral grafts and 154 patients had 156 femorofemoral grafts. The early mortality rate was 6 per cent for the iliofemoral group and 1.3 per cent for femorofemoral reconstruction. There was a higher reoperation rate in the iliofemoral group (31 versus 16.0 per cent). The cumulative patency rate at 6 years was 75 per cent for iliofemoral bypass and 92 per cent for the femorofemoral procedure (P < 0.01), while the survival rates for the same period were 55 and 74 per cent respectively (P < 0.01). Hospital stay was significantly shorter for patients undergoing femorofemoral bypass (P < 0.05).
