당뇨병성 족부 궤양 환자의 진단 1년 내의 절단율 및 위험 인자의 분석

Purpose: This study investigates the amputation rate within 1 year after the diagnosis of diabetic foot ulcer and its associated risk factors. Materials and Methods: This study enrolled 60 patients with diabetic foot ulcer. The mean and standard deviation age was $64.4{\pm}12.8years$ (range, 32~89 years); the mean and standard deviation prevalence period for diabetes mellitus was $21.0{\pm}7.5years$ (range, 0.5~36 years). The amputation rate was evaluated by dividing the subjects into two groups - the major and minor amputation groups - within 1 year following the initial diagnosis of diabetic foot ulcer. Multivariate Cox proportional hazards regression analysis was used to identify the risk factors for amputation. Results: The total amputation rate of 38.3% (n=23) was comprised of the amputation rate for the major amputation group (10.0%) and rate for the minor amputation group (23.8%). There was a high correlation between peripheral artery disease (toe brachial pressure index
