摘要
目的探讨彩色多普勒检查,在糖尿病患者下肢动脉病变诊断中的应用价值。方法糖尿病组70例,非糖尿病组35例,分别应用彩色多普勒超声观察双侧股总动脉、股浅动脉、股深动脉、腘动脉、足背动脉的血管内径、内-中膜的厚度、收缩期最大峰值血流速度、舒张期末血流速度、搏动指数、阻力指数;观察血管内有无硬化斑块、有无完全性和不完全性动脉闭塞。结果糖尿病组较非糖尿病组动脉内膜增厚(P<0.01),动脉硬化斑块发生率90%。各项血流参数提示,在股动脉糖尿病和非糖尿病组之间差异不显著(P>0.05);在腘动脉和足背动脉糖尿病组的PSV和EDV低于非糖尿病组,血流阻力指数明显高于非糖尿病组(P<0.05),严重者发生下肢动脉不完全性或完全性闭塞。结论彩色多普勒超声检查可对糖尿病伴动脉硬化程度的评估提供客观依据。
Objective To assess the value of color Doppler uhrasonography in the diagnosis of lower extremity arterial disease in diabetes. Methods There were to patients of diabetes and 35 patients of non-diabetes in this study. The diameter, inter median thickness（IMT）, peak systolic velocity（PSV）, end diastolic veloeity（EVD）, pulsatility index, and resistance index of bilateral common femoral artery, superficial femoral artery, profunda femoral artery, popliteal artery,and pedal artery,and whether there was arteriosclerotic plaque or occlusive diseases were examined with color Doppler uhrasonogh. Results In diabetic group, the IMT was thicker than that in non-diabetic group （P〈0.01）, and the arteriosclerotic plaque was observed in 90% patients . There was no difference of flow parameters in femoral arteries between two groups. However, the PSV and EDV in popliteal artery and pedal artery was decreased in diabetes, and resistance index was significantly increased （,o〈0.05）. Arterial complete and incomplete occlusion were observed in severe cases. Conclusion Color Doppler uhrasography is an ideal method to evaluate the arteriosclerotic degree of lower extremity arterial diseases in diabetes.
