摘要：目的 观测缺血性脑卒中颅外段颈动脉狭窄的发生率及粥样硬化斑块性质;了解患者牛津郡社区卒中项目(OCSP)分型与颅外段颈动脉病变之间的关系.方法 纳入并登记2008年1月至2009年12月郑州大学第一附属医院神经内科连续入院的缺血性脑卒中患者,行颈部双功能彩色多普勒超声检查,观测患者的颈动脉狭窄程度及粥样斑块性质.结果 符合标准的缺血性脑卒中患者854例,其中675例(79%)患者进行了颈动脉彩超检查,OCSP各亚型构成比如下:部分前循环梗死占32.7%,腔隙性脑梗死占26.1%,完全前循环梗死占23.0%,后循环梗死占18.2%.颅外段颈动脉狭窄215例(31.9%),其中颈动脉狭窄≥50%包括颈动脉闭塞在内共93例(13.8%).在386例(57.2%)患者中共检出515个粥样硬化斑块,其中不稳定斑块占51.0%,发生部位以颈动脉分叉处最常见,占61.5%(317/515).OCSP亚型间比较,重度颈动脉狭窄患者中,部分前循环梗死发生率最高(14.5%),中度颈动脉狭窄患者中,完全前循环梗死发生率最高(22.6%),且不稳定斑块的检出率最高(P＜0.05).结论 缺血性脑卒中患者颈动脉病变常见,OCSP分型可能与颈动脉病变有相关性. Abstract： Objective To observe the incidence of extracranial carotid artery stenosis and plaque nature,and to understand the relationship between Oxfordshire community stroke project (OCSP) classification and extracranial carotid artery in ischemic stroke. Methods From Jan. 2008 to Dec. 2009 in department of neurology of the first affiliated hospital of Zhengzhou university, the consecutive patients with ischemic stroke admitted to hospital were registered, and by neck color Doppler ultrasound the degree of carotid stenosis and the characteristics of atherosclerotic plaque were recorded.Results Eight hundred and fifty-four cases of ischemic stroke were registered in two years, of which 675 cases (79%) underwent carotid ultrasonography examination. The proportion of ischemic stroke subtyp
