摘　　要：目的:分析彩色多普勒超声联合踝臂指数检测在2型糖尿病下肢血管病变诊断中的效能。方法:回顾性分析2021年6月至2023年6月该院收治的90例疑似2型糖尿病下肢血管病变患者的临床资料,以数字减影血管造影结果为金标准,比较彩色多普勒超声、踝臂指数单项及联合检测诊断2型糖尿病下肢血管病变的效能。结果:90例疑似2型糖尿病下肢血管病变患者中,金标准诊断阳性53例,阴性37例;彩色多普勒超声检测诊断阳性51例,阴性39例;踝臂指数检测诊断阳性52例,阴性38例;联合检测诊断阳性52例,阴性38例;彩色多普勒超声联合踝臂指数检测诊断2型糖尿病下肢血管病变的灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于二者单项检测,漏诊率、误诊率均低于二者单项检测,差异有统计学意义(P<0.05)。结论:彩色多普勒超声联合踝臂指数检测诊断2型糖尿病下肢血管病变的效能高于二者单项检测。Objective:To analyze efficiency of color Doppler ultrasound combined with ankle-brachial index in diagnosis of lower extremity vascular disease in patients with type 2 diabetes mellitus.Methods:The clinical data of 90 type 2 diabetes mellitus patients with suspected lower extremity vascular disease admitted to the hospital from June 2021 to June 2023 were retrospectively analyzed.Using the results of digital subtraction angiography as the gold standard,the efficiencies of color Doppler ultrasound,ankle-brachial index and combined detection in the diagnosis of lower extremity vascular disease in the patients with type 2 diabetes mellitus were compared.Results:Among the 90 type 2 diabetes mellitus patients with suspected lower extremity vascular disease,53 cases were diagnosed as positive and 37 cases were negative by gold standard.The color Doppler ultrasound diagnosis was positive in 51 cases and negative in 39 cases.The ankle brachial index showed 52 positive cases and 38 negative cases.The combined detection showed 52 positive cases and 38 negative cases.The sensitivity,the specificity,the accuracy,the positive predictive value and the negative predictive value of color Doppler ultrasound combined with ankle-brachial index in the diagnosis of lower extremity vascular disease in the patients with type 2 diabetes mellitus were higher than those of the two single tests,the missed diagnosis rate and the misdiagnosis rate were lower than those of the two single tests,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of color Doppler ultrasound combined with ankle-brachial index in the diagnosis of lower extremity vascular disease in the patients with type 2 diabetes mellitus is higher than that of single detection.
