Abstract：Objective To evaluate clinical significance of WIFi classification issued by American Society for Vascular Surgery in 2014 , predict the effectiveness of revascularization for diabetic foot patients with peripheral vascular disease. Methods The total of 109 diabetic foot patients with peripheral artery disease successfully conducted re-vascularization between January 2013 and January 2016 in Affiliated Sixth People’s Hospital, Shanghai Jiao Tong University were divided into two groups. Sixty-four patients whose wound healed successfully were set into observation group, while forty-five patients with non-healing wound as the controlled group. Clinical data, WIFi classification of those patients were analyzed retrospectively. The high risk factors of wound healing were analyzed by single factor, multiple factor and Logistic regression analysis. Results There was no significant difference in clinical data such as age, gender, ABI, HbA1c,TC, blood glucose,the course of diabetes and ratio of cardiovascular and cerebrovascular diseases between the two group(P>0.05). Single factor regression analysis showed that there was significant difference between two groups in the W and I classification system(P<0.01). Multiple factors regression analysis indicated that wound and ischemia grade were independent risk factors of wound healing time after re-vascularization. Logistic regression analysis displayed that serious I grade in the WIFi classification system was predictive independent risk factors of wound healing time after re-vascularization(P<0.01). Conclusion Using WIFi classification system to evaluate the risk of wound healing after re-vascularization among diabetic foot patients with peripheral artery disease has a better prediction and evaluation value.
