【摘要】 目的探讨颈动脉彩色多普勒超声检测老年脑梗死患者的粥样硬化斑块的临床价值。方法应用彩超多普勒超声对48例老年脑梗死患者(梗死组)和42例无脑梗死老年人(对照组)的颈动脉内中膜厚度(IMT)、斑块类型及斑块形态进行检测。结果梗死组37例颈动脉有不同程度的粥样硬化斑块形成,发生率为77.09%。对照组10例有不同程度的粥样硬化斑块形成,发生率为23.81%,两组比较,差异有统计学意义(P<0.05)。梗死组颈动脉斑块以脂质型为主,表面多呈不规则型。梗死组和对照组颈动脉IMT分别为(1.22±0.31)mm、(0.68±0.16)mm,两组比较,差异有统计学意义(P<0.05)。结论脑梗死与颈动脉粥样斑块密切相关。颈动脉超声是检测颈动脉粥样硬化斑块方便有效方法,对预防老年脑梗死的发生有重要的临床应用价值。更多还原

【Abstract】 Objective To explore the clinical value of Color Doppler ultrasound in detecting atherosclerotic plaque of caroid artery in elderly patients with cerebral infarction.Methods Color Doppler ultrasound was used to detect carotid artery intima-medium thickness(IMT),type and morphology of atherosclerotic plaque in patients with cerebral infarction and patients without cerebral infarction.Results Carotid artery plaque was observed in 37 cases(77.09%)in the cerebral infarction group and 10 cases(23.81%) in the control group,the difference had statistical significance(P<0.05).The plaque of the cerebral infarction group presented dominantly lipid type with irregular surface.IMT was(1.22±0.31)mm in the cerebral infarction group and(0.68±0.16)mm in the control group,the difference had statistical significance(P<0.05).Conclusion Cerebral infarction is related with carotid artery plaque.Color Doppler Ultrasound is a convenient and effective method to investigate carotid artery plaque,which has important clinical value in preventment of the onset of cerebral infarction.更多还原
