超声检测糖尿病患者无名动脉分叉处的临床意义

Clinical Significance of Ultrasound on Innominate Artery Bifurcation

目的:探讨高频超声对糖尿病动脉硬化的诊断意义,比较颈部动脉斑块好发部位的差异,分析动脉粥样硬化斑块形成的独立危险因素。方法:使用彩色多普勒超声对58例糖尿病患者及41例非糖尿病患者进行检查,观察颈部动脉分叉处斑块形成情况,分析收缩压及糖化血红蛋白对斑块的影响。结果:糖尿病组颈部动脉斑块的发生率明显大于正常组,两组间有显著差异(P<0.05),年龄及与收缩压是动脉粥样硬化斑块形成的独立危险因素。正常对照组无名动脉分叉处粥样硬化斑块发生比例较糖尿病组高,二者差异显著(P<0.05)。左侧颈总动脉分叉处、右侧颈总动脉分叉处及无名动脉分叉处粥样硬化斑块的发生率无显著差异(P>0.05)。结论:糖尿病患者动脉粥样硬化的发生率明显高于正常人群,并随年龄及收缩压的增加而加重。无名动脉分叉处与颈总动脉分叉处同为动脉粥样硬化斑块的好发部位。

Objeetive：To explore the clinical significance of color Doppler sonography study in diabetes atheroselerotie and where is more prone parts of carotid artery plaques, analysis of atherosclerotic plaque formation of an independent risk factor. Method：58 patients with diabetes and 41 nondiabetie patients were examined by color Doppler ultrasound to observe the bifurcation of carotid artery plaque formation and to analyze the systolic blood pressure and glycosylated hemoglobin on the impact of plaque. Results：Carotid artery plaque in the diabetic group were significantly greater than the normal control group, there are significant differences between the two groups （P 〈0.05）, systolic blood pressure and age are the independent risk factor of an atherosclerotic plaque formation . compared with diabetic group ,innominate artery bifurcation atherosclerotic plaque is more than In normal group, the difference is significant （P 〈0.05）. Left and right common carotid artery bifurcation, and innominate artery bifurcation plaque was no significant difference （P〉 0.05）. Conclusion：The atherosclerosis in patients with diabetes were significantly higher than the normal population, and increases with age and systolic blood pressure increased. Innominate artery bifurcation and common carotid artery bifurcation is the same predilection sites of atherosclerotic plaque.
