Abstract: | Between January 1, 1985, and December 31, 1988, we prospectively studied the outcome of 62 consecutive below-knee amputations with primary closure in 56 patients. There were 35 men and 21 women; mean age was 70 years. Above-knee amputation was performed for occlusion of the profunda femoris artery, acute thrombosis of a popliteal aneurysm with inadequate sural artery vascularity, intractable knee flexion contracture, suspended ischemia, and occasionally, when ischemia was found intraoperatively to extend proximally during below-knee amputation. Bedridden patients deemed unfit for prosthetic devices were also candidates for above-knee amputation. Fifty-four lower extremities (87%) were gangrenous and rest pain was present in eight patients (13%). Twenty-nine limbs (47%) were amputated primarily, 33 (53%) after failure of one or more revascularization procedures. Six patients had bilateral amputation. Forty patients (71%) were diabetic. Mean hospital stay was five days. Fifteen patients (27%) died during a mean follow-up period of 29 months. Eleven stumps (17.5%) required reoperation: five for postoperative infection, four for wound breakdown after a fall, and two for secondary abscess. Three secondary above-knee amputations (5%) were necessary. Of 44 below-knee amputations in diabetic patients, one had to be revised at the level of the thigh. Of 33 amputations after revascularization failure, one secondary above-knee amputation was necessary. Restoration of preischemic status was achieved after a mean of 58 days. Upon patient discharge from a rehabilitation center, 44 stumps (81%) were suitable to be fitted with prostheses. Compared with the open-stump technique, primary closure of below-knee amputation stumps reduces healing time without an increased reoperation rate. Hospitalization is short and reestablishment of patient autonomy is rapid.Presented at the Annual Meeting of the Société de Chirurgie Vasculaire de Langue Française, Strasbourg, France, June 23–27, 1989. |
