Abstract
Abstract Objectives Several classifications have been published to predict limb salvage in diabetic patients with non-healing ulcer to aid in the management plan. The Society for Vascular Surgery (SVS) Lower Extremity Guidelines Committee has composed a new classification system that reflects the three major factors that impact amputation risk and clinical management Our goal was to evaluate the predictive ability of this wound, ischemia and foot infection(WIfI) classification as a predictor of limb salvage in diabetic patients with non-healing ulcer Methods a prospective single arm observational cohort study conducted on 50 patients within 2022 at single center, Ain Shams University Hospitals, Patients are diabetics who had non healing ulcers some of the cases underwent angioplasty or debridement, then follow up of the wounds was done. Limbs were stratified into clinical stages 1 to 4 based on the SVS WIfI classification for amputation risk. Results Our study included 38 males (76%) and 12 females (24%). The age range between 35 years and 73 years with mean age of 59±8.81. All of the patients are diabetic. The percentage of patients with hypertensive ( 76 %), 54% of them were smoker & 7 were suffering from ESRD. limb salvage was achieved on 75 % of cases. All cases have been classified according to WIFI classification into clinical stages I-IV and their percentage were 6%,12%,40% and 42% respectively. WIfI classification was significant in predicting the major or minor amputation as well as ulcer healing. As Major amputation among each WIfI classification group low, moderate and high risk was 0%, 10%, 47% respectively. Risk of minor amputation was 22%, 40% and 76% respectively. While ulcer healing was 100%, 85% and 52% respectively. Conclusion The likelihood of an amputation after one year in patients with non healing ulcer increases with higher WIfI stages, so The WIfI classification is applicable in prediction of limb salvage in diabetic patients with non-healing ulcer. Smoking and aging also decreases the chance of limb salvageability
