Changing patterns in the predisposition for amputation of the lower extremities.
The purpose of this study was to evaluate and determine the role of diabetes and other common predisposing factors in amputation of the lower extremities. A retrospective review of 110 patients with peripheral vascular disease who underwent amputation between 1987 and 1990 at Hahnemann University Hospital (Philadelphia, PA) was performed. Patients who underwent amputations for trauma or cancer were excluded from this analysis. The patients were divided into four groups according to the site of amputation: Above Knee (n = 43), Below Knee (n = 26), Foot (n = 7) and Transmetatarsal (n = 34). The mean age was 60 years. Fifty-five patients (51%) were white. Sixty-four patients (58%) were men. Twenty-nine patients (26%) were cigarette smokers; sixteen smokers (55%) had above-knee amputation. Thirty-five patients (32%) had previous vascular surgery of the lower extremities. The combination of diabetes and hypertension was present in 40 patients (36%). When either diabetes or hypertension alone was present in a patient, hypertension, not diabetes, was more commonly the dominant underlying medical condition in patients with amputation (32 hypertension-alone patients vs. 10 diabetes-alone patients). The high frequency of hypertension suggests that enhanced control of this disease may affect peripheral vascular disease and related amputations in the future.
