摘要
目的评价踝／肱动脉压比值（ABI）在糖尿病周围动脉病变（PAD）诊断中的价值，并探讨其在临床的适用性。方法对符合入选标准的88例2型糖尿病患者进行间歇性跛行问卷调查、足部动脉触诊、下肢动脉彩色多普勒超声检查以及ABI检测，以多普勒超声诊断结果为标准，计算间歇性跛行问卷、足部动脉触诊、ABI≤0．9诊断PAD的敏感度、特异度、阳性预测值、阴性预测值、准确度以及Kappa值（．c值）。结果ABI≤0．9诊断糖尿病PAD的敏感度、特异度和准确度分别为75．00％、96．80％和91．12％，与彩色多普勒超声检查之间一致性极好（K=0．76±0．06）。结论多普勒ABI检测操作简便、无创，可用于门诊及住院糖尿病患者无症状PAD初步筛查以及流行病学调查。
Objective To evaluate the efficacy of ankle-brachial index（ABI） in the diagnosis of diabetic peripheral arterial disease（PAD）.Methods 88 patients with type 2 diabetes underwent the 4 simple tests：Edinburgh Claudication Questionnaire evaluation,foot arterial palpation,lower extremity artery with color Doppler ultrasonography and ABI examination.Using the results of Color Doppler Ultrasonography as criteria,the sensitivi- ty, specificity, positive and negative predictive values,accuracy and kappa values of these tests were analyzed.Results The sensitivity, specificity and accuracy of ABI ~〈 0.9 were 75.00% ,96.80% and 91.12%,respectively.ABI 〈~ 0.9 and Color Doppler Ultrasonography showed good agreement in the diagnosis of diabetic peripheral neuropathy（ K = 0.76 ＋ 0.06）.Conclusion ABI is a non-invasive and reliable diabetes clinics and epidemiological surveys. tool for screening asymptomatic diabetic PAD in both
