摘　　要：目的探讨彩色多普勒超声评价颈动脉易损性斑块声像特征、评估与缺血性脑血管意外危险性的相关性。方法对有颈动脉硬化斑块患者分为观察组(脑血管意外组)及对照组(非脑血管意外组),应用彩色多普勒超声检查分别记录颈动脉粥样硬化斑块的大小、数目及声像特征,评估不同斑块与脑血管意外的相关性。结果脑血管意外组患者颈动脉易损性斑块(软斑、溃疡斑、窄底硬斑)检出率明显高于非缺血性脑血管意外组(P<0.05),稳定性斑块(扁平斑、宽底硬斑)检出率间差异无统计学意义(P>0.05)。结论颈动脉彩色多普勒超声技术可应用于评价颈动脉斑块易损性及评估与缺血性脑血管意外的相关性。Objective To probe the the ultrasonical appearance of carotid vulnerable plaques and assess the relativi- ty between the carotid vulnerable plaques and risks of ischemic cerebrovascular disease by Color Doppler Ultrasound. Methods The patients having carotid plaques were divided into observation group （cerebrovascular accident group） and control group （ non-cerebrovascular accident group）, the size ,number and nature of carotid atherosclerotic plaques were de- tected by Color Doppler Ultrasound. And the relativity between the carotid vulnerable plaques and risks of ischemic cerebro- vascular disease was by assessed line Logistic regression analysis. Results The carotid vulnerable plaque in patients with ischemic cerebrovascular disease were higher than the patients with non-ischemic cerebrovascular disease （ P 〈 0.05 ）. The detection rate of carotid stable plaques between the two groups have no statistical significance （ P 〉 0. 05 ）. Conclu- sion The Color Doppler Ultrasound can assess the carotid vulnerable plaques and the relativity associated with ischemic cerebrovascular disease.
