[摘要]目的 探讨分析彩色多普勒超声在检测脑梗死患者颈动脉粥样硬化中的应用价值。方法 选择于2011年4月～2013年8月在我院接受治疗45例脑梗死患者设为观察组，45例不存在脑梗死的人群设为对照组，应用彩色多普勒超声检查两组人群是否存在颈动脉粥样硬化斑块、梗死侧和非梗死侧颈动脉内中膜厚度、斑块的部位、大小及其数目、动脉狭窄程度。结果 观察组的颈动脉粥样硬化斑块存在率为84.44%，显著高于对照组的22.22%，两组比较差异显著（P＜0.05），具有统计学意义；研究显示颈动脉主要出现在脑梗死一侧，斑块大小及其数量与脑梗死有明显的相关性，颈动脉内中膜厚度、狭窄程度无明显差异。结论 颈动脉粥样硬化是引起脑梗死的危险因素之一，预防斑块的形成对避免脑梗死的发生有十分重要的意义；彩色多普勒超声能够及早检查斑块的存在，确定斑块的性质，具有较高的临床应用价值。

[Abstract] Objective To investigate the application value of color Doppler ultrasound in detecting carotid atherosclerosis in the patients with cerebral infarction. Methods Forty-five patients with cerebral infarction treated in our hospital from April 2011 to August 2013 were selected as the observation group and 45 patients without cerebral infarction were selected as the control group.The color Doppler ultrasound was used to examine whether there existed carotid atherosclerotic plaque in the two groups and the intima-media thickness,location,size and number of plaque, and arteriostenosis degree of the infarct-side and non-infarct-side carotid arteries. Results The existence rate of carotid atherosclerotic plaque of the observation group was 84.44%,which was significantly higher than the 22.22% of the control group, with statistically significant difference between the two groups(P＜0.05).The study showed that the carotid arteries mainly appeared on the side of cerebral infarction;The size and number of plaque was obviously correlated to the cerebral infarction;The intima-media thickness and arteriostenosis degrees of the carotid arteries were not significantly different. Conclusion Carotid atherosclerosis is a risk factor of cerebral infarction and the prevention of plaque formation is of highly important significance to avoid the occurrence of cerebral infarction.Color Doppler ultrasound can examine the plaque disease and determine the plaque nature early and therefore is of high clinical application value.

脑梗死是临床上在中老年人群中常见的疾病，其死亡率和致残率均较高，症状较轻的患者无任何临床表现和特征，症状较重的患者会引起瘫痪更有甚者出现癫痫与休克，严重影响老年患者的生活质量，因此受到世界医学界的广泛重视[1-2]。随着对脑梗死危险因素研究不断深入，发现颈动脉粥样硬化斑块是诱发脑梗死高危因素，为了解脑梗死与颈动脉粥样硬化斑块之间的关系，同时探讨分析彩色多普勒超声在检测脑梗死患者颈动脉粥样硬化中的应用价值，具体报道如下。……
