目的：：分析脑梗死患者颈动脉粥样硬化斑块的声像学特点，探讨彩色多普勒超声在脑梗死预防及治疗中的应用价值。方法：选择100例脑梗死患者(观察组)和100例健康体检者(对照组)，分析二者颈动脉彩色多普勒超声检查结果。结果：观察组93例(93.00%)发现颈动脉斑块，累计斑块数量189处；对照组16例(16.00%)发现颈动脉斑块，累计斑块数量28处，差异具有显著性(P<0.05)，但斑块分布情况相似，差异无统计学意义(P>0.05)。观察组患者以软斑居多(44.44%)，而对照组体检者以硬斑居多(57.14%)，差异存在显著性(P<0.05)。观察组患者颈总动脉总干内膜-中层厚度(CCA-IMT)和颈总动脉分叉处内膜-中层厚度(BIF-IMT)均大于对照组，差异存在显著性(P<0.05)。观察组患者颈总动脉收缩期峰值流速( SPV)、舒张末期峰值流速( EDV)低于对照组，而阻力指数( RI)高于对照组，差异有统计学意义( P<0.05)。结论：脑梗死患者颈动脉斑块数量明显增加，以软斑为主，内膜-中层厚度增加，血流速度减慢，而彩色多普勒超声检查可尽早发现颈动脉粥样硬化斑块，判定其性质，为脑梗死的预防及治疗提供重要信息。

Objective: To analyze the ultrasonic imaging features of carotid atherosclerotic plaques in cerebral infarction patients and investigate the application values of color doppler ultrasonography in preven-tion and treatment of cerebral infarction.Method: 100 cerebral infarction patients (observation group) and another 100 healthy people ( control group) were selected, and the results of color doppler ultrasonography on the carotid arteries of the two groups were analyzed. Result: Of the observation group, total 189 carotid artery plaques were observed in 93 patients ( 93. 00%); while of the control group, total 28 carotid artery plaques were observed in 16 people (16.00%); and the difference was statistically significant (P<0.05), but the patchiness conditions of the two groups were similar and the difference was statistically insignificant (P>0.05). In the patients of the observation group, most (44.44%) were soft plaques, while in the people of the control group, most (57.14) were hard plaques, and the difference was statistically significant (P<0. 05) . The patients of the observation group had larger common carotid artery intima -media thickness ( CCA-IMT) and bifurcation intima - media thickness ( BIF-IMT) than the control group, and the differences were both statistically significant ( P<0.05) . The patients of the observation group had lower systolic peak ve-locity ( SPV) and end diastolic velocity ( EDV) of the common carotid arteries, but higher resistance index ( RI) of the common carotid arteries than the control group, and the differences as statistically significant ( P<0. 05 ) . Conclusion: Cerebral infarction patients had significantly increased number of carotid artery plaques, which are mainly soft, increased CCA-IMT and decreased blood flow velocity. Color doppler ultra-sonography can discover carotid atherosclerotic plaques and determine the nature as early as possible, and consequently provide important information for the prevention and treatment of cerebral infarction.
