[摘要]目的 探讨彩色多普勒超声诊断在糖尿病下肢动脉病变中的诊断价值。方法 选取2015年12月～2017年3月在本院就医的80例糖尿病下肢动脉病变患者作为研究对象，分别予以CT诊断、彩色多普勒超声诊断，比较两种诊断方法的检出率。结果 彩色多普勒超声诊断的下肢动脉病变TMT检出率为87.50%，粥样硬化斑块检出率为84.29%，血管狭窄、闭塞检出率为86.27%，高于CT诊断的67.50%、60.00%、45.10%，差异有统计学意义（P<0.05）。彩色多普勒超声诊断的诊断后斑块发生部位准确率亦优于CT诊断，差异有统计学意义（P<0.05）。结论 彩色多普勒超声诊断糖尿病下肢动脉病变的效果显著，值得推广实施。

[Abstract]Objective To explore the diagnostic value of color Doppler ultrasonography in diabetic lower extremity arterial disease.Methods 80 patients with diabetic lower extremity arterial disease treated in our hospital from December 2015 to March 2017 were selected as the subjects，CT diagnosis and color Doppler ultrasonography were used，the detection rates of the two diagnostic methods was compared.Results The detection rate of TMT in patients with lower extremity arterial disease by color Doppler ultrasonography was 87.50%，the detection rate of atherosclerotic plaque was 84.29%，and the detection rate of vascular stenosis and occlusion was 86.27%，which was higher than 67.50%，60.00% and 45.10% of CT diagnosis.The accuracy of color Doppler ultrasonography in diagnosis of plaque location was superior to CT diagnosis，with significant difference （P<0.05）.Conclusion Color Doppler ultrasonography is effective in the diagnosis of diabetic lower extremity arterial disease.It is worthy to be popularized and implemented.

糖尿病下肢动脉病变为糖尿病下肢动脉狭窄或闭塞所致的糖尿病并发病证，是糖尿病病足的主要致病因素，亦为导致患者截肢的主要因素[1-4]，甚至危及生命。当患者确诊为糖尿病下肢动脉病变时，应尽早予以血管再通术式治疗，故糖尿病下肢动脉病变的早期诊断是后期制訂医疗方案、提高治愈成功率、提高患者生活质量的关键[3-9]。本研究选取本院收治的糖尿病下肢动脉病变患者作为研究对象，分别予以CT诊断、彩色多普勒超声诊断，并将其诊断结果进行对比，旨在探讨糖尿病下肢动脉病变采取彩色多普勒超声诊断的效果，现报道如下。
