颈动脉粥样硬化斑块的超声表现与脑梗死的关系
作者:夏丽女金轶钱玲妃来源:《中国现代医生》2012年第01期
摘要目的探讨颈动脉粥样硬化斑块的超声表现与脑梗死的关系。方法对50例脑梗死患者(脑梗死组)和30例体检中心正常体检者(对照组)进行颈动脉彩色多普勒超声检查。结果脑梗死组颈动脉粥样硬化斑块的检出率明显高于对照组(χ21557,P<001)。脑梗死组中软斑和溃疡斑的检出率均明显多于对照组(χ2683和596,均P<001),而扁平斑和硬斑的检出率均明显少于对照组(χ2946和937,均P<001)。结论脑梗死的发生与颈动脉粥样硬化,特别是斑块的稳定性关系密切。颈动脉彩色超声检查可早期评价和判断动脉粥样硬化的进展程度,为脑梗死的治疗和预后判断提供依据。

近年来研究发现颈动脉粥样硬化斑块,特别是斑块的稳定性是脑梗死的主要病因和病理学基础1。而引起脑梗死病变的部位不在颅内段颈动脉而在颅外段颈动脉2。为此,我们对我院2009年1月~2010年12月住院的脑梗死患者的颅外段颈动脉进行彩色多普勒超声检测,以探讨颈动脉粥样硬化斑块与脑梗死的关系。现报道如下。
