彩色多普勒超声对脑梗死与颈动脉粥样硬化的相关性分析

Analysis on the correlation between carotid artery atherosclerosis and ischemic infarction via color Doppler ultrasonography

目的探讨颈动脉粥样硬化斑块与脑梗死的关系。方法将病例分为脑梗死组及非脑梗死组,使用彩色多普勒超声检测颈动脉内膜-中层的厚度(intima-medium thickness,IMT)及粥样硬化斑块。结果70例脑梗死患者44例颈总动脉IMT增厚,颈动脉粥样硬化斑块检出率85%;70例非脑梗死者10例颈总动脉IMT增厚,粥样硬化斑块检出率33%,2组有显著差异(P<0.001)。结论颈动脉粥样硬化与脑梗死密切相关。彩色多普勒超声是检测颈动脉粥样硬化斑块最简捷的方法,能早期发现颈动脉粥样硬化,对临床预防脑梗死有重要意义。

Objective To analyze the relationship of carotid artery atherosclerosis plaque and cerebral infarction . Methods Color Doppler ultrasonography was used to investigate carotid artery intima-medium thickness（IMT） and carotid artery atherosclerosis plaque in patients with cerebral infarction and without cerebral infarction. Results In 70 patients with cerebral infarction , IMT increasing was found in 44 cases and carotid artery atherosclerosis plaque was observed in 60 cases （85 %）. In 70 patients without cerebral infarction, IMT increasing was found in 10 cases and carotid artery atherosclerosis plaque was observed in 23 cases （33 %）, those of two groups were different significantly. Conclusion Cerebral infarction is related with carotid artery atherosclerosis plaque. Color Doppler ultrasonography is a convenient and effective method to investigate carotid artery plaque and can find carotid artery atherosclerosis earlier, it is important to prevent the onset of ischemic infarction.
