目的:评价彩色多普勒超声对糖尿病(DM)下肢血管病变(LEAD)的诊断应用价值。方法:DM患者106例与100例同期健康志愿者进行下肢血管彩色多普勒超声检查对照。结果:糖尿病组106例患者,发现100例下肢动脉有不同程度粥样硬化改变,检出率为94.3%。糖尿病组的血管内径较对照组明显减低;血流量亦较对照组减低。结论:彩色多普勒超声是DM患者下肢血管病变检查的有效手段,对早期诊断、预防及治疗具有重要的临床应用价值。
Objective: To evaluate the diagnostic value of color Doppler ultrasonography in the diagnosis of diabetic lower extremity vascular lesions (LEAD). Methods: 106 cases of DM patients and 100 cases of healthy volunteers at the same time lower extremity vascular color Doppler ultrasound examination control. Results: In 106 patients with diabetes mellitus, 100 cases of lower extremity arteries were found to have atherosclerotic changes with a detection rate of 94.3%. Diabetic group’s vascular diameter was significantly lower than the control group; blood flow was also lower than the control group. Conclusion: Color Doppler ultrasonography is an effective method for the examination of lower extremity vascular lesions in patients with DM, which has important clinical value for early diagnosis, prevention and treatment.
