Impact of diabetes mellitus on outcomes of patients with femoropopliteal artery stenting / 中华普通外科杂志

ABSTRACT

Objective To analyze the influence of diabetes mellitus (DM) on the outcomes of percutaneous transluminal angioplasty (PTA) with stenting of femoropopliteal artery,in patients with atherosclerotic occlusive disease (ASO).Method Clinical data of inpatients who successfully received PTA with stenting procedures of femoropopliteal artery in Xuanwu Hospital from January 2006 to December 2012 were analyzed retrospectively.Patients were stratified into DM and non-DM groups.Results were compared between the two groups including primary patency (PP),assisted patency (AP),limb salvage and survival using Kaplan-Meier life table and Cox regression analyses.Result Totally 291 patients underwent 332 procedures.There were 214 DM and 118 non-DM limbs.Mean follow-up was 34 months.The 5-year PP was 23.2％,AP was 35.3％,limb salvage was 89.2％,and survival was 69.6％.DM was associated with lower 5-year PP,limb salvage,and survival than non-DM.But there were no significant difference in AP between the two groups.Females were associated with decreased PP than males on Cox multivariate analysis.Hypertension and below tibial diseases were associated with lower limb salvage rate and age is the only predictor of survival rate.Conclusions DM is a risk factor for poor outcomes after PTA with stenting procedures.
