摘　　要：目的探讨颈动脉粥样硬化中老年脑梗死的危险性。方法应用彩色多谱勒超声对81例中老年脑梗死患者及65例与之年龄匹配的无脑梗死人群进行对照研究,观察其颈动脉内膜中膜厚度(IMT)、斑块结构及管腔狭窄情况。结果脑梗死组颈动脉斑块发生率为80.27%,显著高于对照组(46.70%,P<0.0001)。斑块类型中软斑块及溃疡斑所占的比率、颈总动脉IMT增厚和颈动脉中度(51%～70%)及重度(>71%)狭窄的发生率脑梗死组高于对照组,均有显著性差异。结论老年人颈动脉粥样硬化斑块类型、IMT增厚及管腔狭窄是脑梗死的危险因素。Objective To eluciate the risk effects of carotid atherosclerosis on cerebral infarction in the elderly.Methods With color Doppler image, the comparative study in 81 elder cerebral infarction patients and 65 age-matched controls was applied to examine the carotid intima-media thickness, plaque constructures and the degree of artery stenosis. Results The prevalence of carotid plaque in the patients were significantly higher than that in controls （80.27% vs 46.70%,P〈 0.0001）. The rates of soft and ulcerated carotid plaque, the incidence of intima-media thinkening in common carotid and the incidence of moderate （51%-70%） and severe （〉71%） stenosis in carotid were significantly higher in patients than controls. Conclusions The carotid plaque , intima-media thickness and stenosis were risk factors of cerebral infarction in the elderly.
