目的 分析和评估超声在诊断糖尿病患者颈动脉及下肢动脉硬化中临床应用价值。方法 选择本院于2014年10 月～2017年2月间收治的100例糖尿病患者与同期100例非糖尿病患者为研究主体。设定为A组和B组，均给予彩色 多普勒超声检查。对比两组颈动脉与下肢动脉的检测结果。结果 A组颈动脉的IMT（颈动脉内膜中层厚度）发生 率（86.00%）、斑块检出率（62.00%）与狭窄发生率（36.00%）均高于B组的23.00%，16.00%和14.00%，对比差 异明显，有统计学意义（P＜0.05）。A组下肢动脉的IMT发生率（82.00%）、斑块检出率（80.00%）与狭窄发生率 （34.00%）均高于B组的15.00%，13.00%和11.00%，对比差异显著，有统计学意义（P＜0.05）。A组中，内膜检查 结果为：近分叉部位的IMT不均匀增厚明显，为62例，发生率是62.00%；下肢动脉内膜粗糙不均匀增厚为80例，发 生率为80.00%。结论 为糖尿病患者进行超声检查，可以较好的诊断出颈动脉与下肢动脉的病变情况，及早发现动 脉粥样硬化的发生，对患者进行有效治疗，其诊断价值显著，安全性高，可推广。

Objective To analyze and evaluate the clinical value of ultrasound in the diagnosis of diabetic patients with carotid and lower extremity arteriosclerosis. Methods In our hospital from October 2014 to February 2017 100 cases of diabetic patients compared with 100 cases of non diabetic patients as the research subject. The set of A group and B group were given color Doppler ultrasound examination. The detection results were compared between the two groups of carotid and lower extremity arteries. Results In A group, the carotid IMT (carotid intima-media thickness) incidence rate (86%),(62%) the detection rate of plaques and stenosis rate (36%) was higher than that of B group was 23%, 16% and 14%, the difference was significant. There was statistical significance (P<0.05) the incidence of lower extremity arteries in. A group IMT (82%),(80%) the detection rate of plaques and stenosis rate (34%) was higher than that of B group was 15%, 13% and 11%, compared with significant difference, with statistical significance (P<0.05). A In the group, endometrial examination results: near IMT bifurcation sites of uneven thickening, 62 cases, the incidence was 62%, lower extremity arterial intimal rough uneven thickening in 80 cases, the incidence rate was 80.00%. Conclusion For patients with diabetes by ultrasonography, can better diagnose lesions of carotid and lower extremity arteries the incidence of atherosclerosis, early detection, effective treatment of the patients, the diagnostic value was high, the security can be extended.
