糖尿病患者颈动脉粥样硬化的高频超声检测

目的探讨2型糖尿病与颈动脉粥样硬化的关系及高频超声检测糖尿病患者颈动脉的意义。方法对临床确诊的2型糖尿病患者58例及正常对照组人群60例行高频超声检测。测量颈动脉内膜-中膜(IMT)厚度,观察管壁有无斑块、斑块性质、分类血流动力学变化。结果糖尿病组颈动脉IMT增厚与斑块形成的发生率与对照组比较差异有显著意义。糖尿病合并脑卒中的患者中,颈动脉IMT增厚的发生率为100%,粥样硬化斑块的发生率达到92.3%。结论糖尿病是颈动脉粥样硬化的易患因素,高频超声能清晰显示糖尿病患者的颈动脉病变情况,为临床诊断和治疗提供重要依据。

Application of high frequency ultrasonography in the examination of carotid arteries of patients with diabetes mellitus

Objective To investigate the relationship of diabetes with carotid artherosclerosis, and to investigate the application of high frequency ultrasonography in the examination of carotid arteries of patients with diabetes. Methods Fifty-eight patients with type-2 diabetes mellitus and 60 normal people were examined by high frequencey ultrasonography. And, the intima-media thickness (IMT) of the carotid arteries, wether or not there was a plaque, what sort is the plaque and the changes of the hemodynamics of the carotid arteries were systemically examined. Results The occurece rate of IMT thickness and artherosclerotic plaque was significantly higher than that of the normal control. Of all the diabetes patients, 13 cases were complicated with cerebral infarction and twelve cases of them were observed to have artherosclerotic plaque. Conclusion Diabetes patients are susceptible to carotid artherosclerosis, and, high frequecy ultrasonography is of great helpful to the diagnosis of arteriol artherosclerosis.
