糖尿病下肢外周动脉血管病变是糖尿病足的关键因素,是导致糖尿病足部溃疡和下肢截肢的主要原因。研究表明糖尿病患者的截肢率是非糖尿病患者的15倍。因此,早期检出糖尿病患者的下肢动脉病变,进行早期干预及治疗,对于改善糖尿病患者的生活及生存质量具有重要意义。踝肱指数是下肢踝部收缩压与上肢肱动脉收缩压的比值,是评估糖尿病下肢血管病变的方法之一,具有操作简便、无创伤性、
Diabetic lower extremity peripheral arterial vasculopathy is a key factor in diabetic foot and is the leading cause of diabetic foot ulcers and lower limb amputation. Studies show that patients with diabetes have an amputation rate of 15 times that of non-diabetic patients. Therefore, the early detection of diabetic lower extremity arterial disease, early intervention and treatment, for improving the quality of life and quality of life of patients with diabetes is of great significance. Ankle-brachial index is the lower extremity ankle systolic blood pressure and brachial artery systolic pressure ratio is to assess the diabetic lower extremity vascular disease, one of the methods, with simple, non-invasive,
