摘　　要：目的探讨踝臂指数(ABI)、下肢动脉彩超在糖尿病下肢血管病变(PAD)中的诊断价值。方法 148例2型糖尿病患者进行ABI、下肢动脉彩超检查,根据四格表法分析ABI及下肢动脉彩超诊断PAD及PAD狭窄或闭塞的检出率,分别计算ABI检测PAD及PAD狭窄或闭塞的敏感度、特异度、阳性似然比、阴性似然比、阳性预测值及阴性预测值。结果下肢动脉彩超对糖尿病下肢血管病变检出率高于ABI(P<0.05)。PAD早期ABI敏感性低,特异性高。PAD动脉狭窄或闭塞时,ABI敏感性明显升高,特异性仍较高。结论 ABI是一种简单、实用及无创的评价下肢动脉狭窄或闭塞的方法,但也有其局限性,超声检查仍是2型糖尿病患者PAD早期诊断的重要手段。【Objective】To study the role of ankle-brachial index（ABI） and peripheral arterial ultrasound in the diagnosis of peripheral artery disease（PAD） with type 2 diabetes.【Methods】ABI and peripheral arterial ultrasound were measured on 148 cases with type 2 diabetes. Their detection rates were compared by fourfold table. And calculate the sensitivity, specificity, positive likelihood ratios, negative likelihood ratios, positive predict value, negative predict value of ABI.【Results】The detection rate of peripheral arterial ultrasound in PAD was higher than ABI（P 0.05）. ABI had a low sensitivity and high specificity in the early stage of PAD. While in the late stage of PAD the sensitivity significantly increased and the specificity remained high.【Conclusion】ABI is a simple, practical, noninvasive method in the diagnosis of lower extremity arterial stenosis or occlusion, but has its limitations, peripheral arterial ultrasound is still an important means of early diagnosis of PAD with type 2 diabetes.
