颈动脉中低回声斑块与前循环缺血性进展性脑卒中的关系研究

The relationship of carotid artery middle-low echo plaque with anterior circulation progressive ischemic stroke

目的探讨前循环缺血性进展性脑卒中与颈动脉中低回声斑块之间的关系。方法急性前循环脑梗死患者260例,根据临床病情发展分为进展组(56例)和非进展组(204例),健康体检者50例作为对照组,比较3组颈动脉粥样斑块的特征。结果进展组颈动脉斑块发生率(92.9%),远高于非进展组(73%),进展组以中低回声斑块(87.5%)为主,发生率远高于非进展组(25.5%)。结论颈动脉中低回声斑块与前循环缺血性进展性脑卒中的发生密切相关。

Objective To explore the role of carotid artery middle-low echo plaque in the pathogenesis of progressive ischemic stroke.Methods 260 patients with acute anterior circulation cerebral infarction and 50 normal controls were investigated.The patients were divided into progressive ischemic stroke（PIS） group（56） and non-progressive ischemic stroke（NPIS） group（204） based on clinical manifestation.We compared characteristics of carotid artery plaque in the three groups.Results The incidence of carotid artery plaque in the progressing group（92.9%） far surpassed it in the non-progressing group（73%）.The ratio of middle-low echo plaque in the progressing group（87.5%） also far surpassed that in the non-progressing group（25.5%）.Conclusion Carotid artery middle-low echo plaques maybe closely related to the arising of anterior circulation progressive ischemic stroke.
