颈动脉彩色多普勒超声检测在缺血性脑血管病的应用价值

目的探讨颈动脉彩色多普勒超声检测在缺血性脑血管病患者中的应用价值。方法应用彩色多普勒超声对99例缺血性脑血管病患者颈动脉进行检测，并与正常对照组比较分析。结果缺血性恼血管病患者颈动脉内中膜厚度（IMT）、软斑和混合斑致中重度狭窄发生率均高于对照组（P〈0．05）；狭窄〉50％可致颈动脉血流动力学发生变化、结论彩色多普勒超声可以早期发现并观察颈动脉粥样硬化的发生和发展过程，能；住确地检测出颈动脉硬化的组织结构学和血流动力学变化，为缺血性脑血管病患者的早期诊断和干预治疗提供重要的参考价值。

Studies on Carotid Artery Atherosclerosis and Cerebral Ischemic Diseases with Color Doppler Ultrasound

Objective To evaluate the value of carotid artery atherosclerosis and the ischemic cerebrovascular diseases with color doppler ultrasound. Methods The carotid arteries of 99 patients with ischemic cerebrovascular diseases were measured with color doppler ultrasound,and 30 normal cases were selected as the contrast group. Results The IMT and the carotid stenosis occurrence rate which was caused by the soft and admixture plaques of the ischemic cerebrovascular group were higher than that of the normal group （ P 〈 0.05） ; There were obvious differences in the carotid arteries＇hemodynamic parameters with the degree of carotid stenosis higher more than 50 percent. Conclusion With the color doppler ultrasound, we can observe the occurrence and development of carotid artery atherosclerosis at early stage.
