摘　　要：目的探讨彩色多普勒超声对糖尿病动脉硬化的诊断意义,并总结糖尿病患者动脉硬化的特点。方法选取80例糖尿病患者和75名健康体检者做对照研究,所有病例均使用彩色多普勒超声检查颈总动脉(CCA)、颈内动脉(ICA)、锁骨下动脉(SA)、无名动脉(IA)、股总动脉(FA)、股浅动脉(SFA)、动脉(PA)、足背动脉(DA),测量动脉内径、内中膜厚度、收缩期最大流速、阻力指数、有无斑块形成及斑块的性质。结果糖尿病组CCA内径、CCA内中膜厚度、ICA内径、ICA内中膜厚度、ICA血流阻力指数、SA内径、FA内径、PA内中膜厚度等参数较健康组明显增大,2组间比较差异有统计学意义(P<0.05);糖尿病组CCA、SA、FA斑块的发生率明显高于健康组(P<0.05);动脉管壁斑块的性质,2组差异无统计学意义。结论糖尿病组血管硬化的发病率明显较高,其血管病变范围更广泛,中、小动脉也明显受累,尤以近端动脉为著;各大血管病变以后壁及血管分支处多见,较前壁有显著差异。Objective To evaluate the diagnostic value of color Doppler ultrasonography in diabetic atheroscle rosis, and summarize the characteristics of arteriosclerosis in diabetic patients. Methods Eighty diabetic patients were randomly selected into the treatment group, while 75 normal people into the control group. All cases were exam ined using the color Doppler ultrasonography for common carotid artery（CCA）, internal carotid artery（ICA）, subclavian artery （SA）, innominate artery（IA）, femoral artery （FA）, superficial femoral artery （SFA）, popliteal artery （PA）, dorsalis pedis artery（DA）. And the arterial inner diameter, the intima-media thickness, the peak systolic velocities, the resis tance index, the sizes and numbers of the plaques in the arteries were obtained. Results The parameters such as in ner diameter and intima-media thickness of CCA; inner diameter, intima-media thickness and blood flow resistance of ICA; inner diameter of SA; inner diameter of FA and intima-media thickness of PA in the treatment group more sig- nificantly increased than the control group （P〈0.05）. The occurrence rate of plaque of CCA, SA, FA was significantly higher in the treatment group than in the control group （P〈0.05）. There was no significant difference in plaque of ar terial wall between the two groups. Conclusion In the treatment group, the incidence rate of angiosclerosis increased obviously, vasculopathy was more extensive, medium and small arteries are significantly affected especially for proxi mal artery, pathological changes of large blood vessels are more extremely common in posterior wall and branches of vessels than in anterior wall of vessels.
