The outcome of leg bypass in women is unknown. To date, most series of lower extremity bypass have included few women, and the results in women compared with those in men have not been reported. The experience with infrainguinal arterial reconstruction in women treated at the Oregon Health Sciences University has been greater than previously reported. We have reviewed our recent experience with lower extremity bypass to determine whether results in women differ significantly from those in men.


In the past 11 years we have performed 823 infrainguinal arterial reconstructions for lower extremity ischemia in 585 patients, of which 357 procedures were performed in women and 466 procedures were performed in men. The mean ages were 65 years for men and 68 years for women. Diabetes was present in 59% of the men and 48% of the women. Among men, 84% had a history of tobacco use compared with 66% of the women. Bypasses in men were performed for limb salvage in 73%, claudication in 22%, and a failing bypass graft in 5% of cases. Bypasses in women were performed for limb salvage in 79%, claudication in 15%, and a failing graft in 6% of cases. Previous revascularizations had been performed in 63% of the men and 71% of the women. Autogenous vein was used in 97% of the bypasses in men and 96% of bypasses in women. Graft distribution among infrainguinal arterial target sites was similar between the groups. Bypasses in men were femoral to above-knee popliteal in 11%, femoral to below-knee popliteal in 40%, femoral to tibial in 38%, popliteal to tibial in 10%, and tibial to tibial in 1% of cases. Bypasses in women were femoral to above-knee popliteal in 14%, femoral to below-knee popliteal in 43%, femoral to tibial in 33%, popliteal to tibial in 9%, and tibial to tibial in 1% of cases.


Perioperative 30-day mortality rates were 3.7% overall, 4.3% in men, and 2.9% in women. Long-term survival at 1, 3, and 5 years in men was 80%, 59%, and 44%, respectively. Long-term survival at 1, 3, and 5 years in women was 83%, 69%, and 44%, respectively. Life-table primary patency rates at 1, 3, and 5 years were 86%, 77%, and 71% for men and 87%, 74%, and 67% for women. Limb-salvage results at 1 and 5 years were 93% and 91% for men and 96% and 96% for women.


These results indicate that long-term graft patency and limb salvage results in women are identical to those obtained in men in this experience with autogenous vein. Infrainguinal arterial reconstruction can be performed in women with mortality rates similar to those of men. In this series long-term survival was similar for both men and women.
