Value of continued efforts at limb salvage despite multiple graft failures.
Treatment of patients with limb-threatening ischemia after multiple failed bypasses remains difficult and controversial. Further revascularization procedures despite failure of the original procedure may be viewed as futile. The purpose of this report is to determine the efficacy of third or fourth revascularization procedures after the original and second procedures fail. Over a 10-year period from January 1, 1983, to December 31, 1992, 312 infrainguinal bypasses were performed on 271 consecutive patients for foot salvage. The overall limb salvage rate was 84%, and the operative mortality rate was 3.7% (10 patients). Sixteen patients (5.8%) had repeat infrainguinal bypasses performed after failure of two or more prior bypass procedures in the same leg. Twenty-three reconstructions were performed in these 16 patients. There were no operative deaths. One half of these patients had major amputations performed within the first year following their tertiary or fourth reconstructive procedure. Sixty-two percent of patients have survived longer than 3 years after their third or fourth procedure. One half of these patients have maintained graft patency and an excellent quality of life. Only 22% of the patients requiring amputation ambulated with a prosthesis, whereas all revascularized patients ambulated. Although this subset of patients is known to have an increased risk of repeated graft failure and limb loss, we believe continued efforts at limb salvage despite multiple previous graft failures is justified.
