[Bilateral aorto-iliac prosthesis. Long-term results].

Over a 12-year period (1975-1987), 565 patients (male: 94.5 percent; female: 5.5 percent) underwent aorto-iliac bilateral reconstruction. The operations were performed by the same surgical team and all patients were followed up for 13 years. The patients'mean age was 59.4 years; 16.6 percent were over 70; 16 percent had a non-fissured aneurysm. The postoperative mortality rates was 2. 8 percent, with relatively few deaths of cardiovascular origin (0.5 percent). The late mortality rate was significantly higher than that of an age-matched control population
