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势,临床上可结合使用。
Objective To investigate the diagnostic value of percutaneous oxygen pressure (TcPO2), ankle brachial index (ABI) and color Doppler ultrasound in the diagnosis of peripheral vascular disease (PVD) in patients with T2DM. Methods TcPO2, ABI and color Doppler echocardiography were performed on the selected patients. The diagnostic results of the three methods were evaluated by sensitivity, specificity, receiver operating characteristic (ROC) curves and so on. Results The sensitivity of TcPO2, ABI and color Doppler ultrasound were 0.917, 0.792 and 0.854, respectively, and the specificity were 0.663, 0.897 and 0.873, respectively. The areas under the ROC curve were 0.791, 0.549 and 0.675 respectively. Conclusion The three diagnostic methods have their own advantages in diagnostic performance and can be used clinically.
