【摘要】目的 探讨经皮氧分压(TcPO2)、踝肱指数(ABI)、彩色超声多普勒在T2DM患者外周血管疾病(PVD)中的诊断价值。 方法 入选患者分别行TcPO2、ABI、彩色超声多普勒检查，用敏感性、特异性、受试者工作特征(ROC)曲线等评估3种检查方法的诊断效果。 结果 TcPO2、ABI、彩色超声多普勒的敏感性分别为0.917、0.792、0.854，特异性分别为0.663、0.897、0.873，ROC曲线下面积分别为0.791、0.549、0.675。 结论 3种检查方法诊断性能各有优劣，临床上可结合使用。

　　【Abstract】Objective To investigate the diagnostic value of transcutaneous oxygen pressure (TcPO2), ankle-brachial index (ABI), and color Doppler ultrasound in T2DM patients with peripheral vascular disease (PVD). Methods The enrolled patients were detected by TcPO2, ABI, and color Doppler ultrasound respectively. The sensitivity, specificity, and receiver operating characteristic (ROC) curve, etc. were calculated to evaluate the diagnostic efficacy of each detecting method. Results The sensitivity of TcPO2, ABI, and color Doppler ultrasound was 0.917, 0.792, and 0.854 respectively, the specificity was 0.663, 0.897, and 0.873 respectively, and the area under the ROC curve was 0.791, 0.549, and 0.675 respectively. Conclusions Each of the three detection methods has its own advantages. It’s better to use them in combination clinically.
