目的探讨彩色多普勒超声检查颈动脉粥样硬化斑块与脑梗死的相关性。方法对本院100例住院的脑梗死患者(观察组)和80例健康体检者(对照组)进行颈动脉彩色多普勒超声检查,观察其颈动脉斑块大小、形状、内部回声特点及颈动脉狭窄情况。结果观察组颈动脉斑块检出率显著高于对照组(P<0.01),观察组中不稳定性斑块的比率显著高于稳定性斑块(P<0.01),对照组中稳定性斑块的比率显著高于不稳定性斑块(P<0.01);观察组以软斑、溃疡斑及混合性斑块为主,对照组以扁平斑、硬斑为主;观察组颈动脉狭窄率显著高于对照组(P<0.05)。结论脑梗死患者颈动脉粥样硬化斑块的发生率高,且大多为不稳定性斑块。提示脑梗死发生与颈动脉狭窄处粥样硬化斑块的稳定性有密切关系。颈动脉彩色多普勒超声检查作为一种无创性检查方法,可及早发现斑块,及早治疗,预防脑梗死的发生。 Objective To investigate the relationship between carotid atherosclerotic plaque and cerebral infarction by color Doppler sonography. Methods 100 cases of hospitalized patients with cerebral infarction (observation group) and 80 healthy subjects (control group) underwent carotid artery color Doppler ultrasonography to observe the carotid plaque size, shape, internal echo characteristics and neck Artery stenosis. Results The carotid plaque detection rate in the observation group was significantly higher than that in the control group (P <0.01). The ratio of unstable plaque in the observation group was significantly higher than that in the stable plaque (P <0.01) (P <0.01). The observation group was predominantly with soft plaque, ulcer plaque and mixed plaque, while the control group was mainly flat plaque and hard plaque. The carotid artery stenosis rate Significantly higher than the control group (P <0.05). Conclusion The incidence of carotid atherosclerotic plaques in patients with cerebral infarction is high, and most of them are unstable plaques. Tip of cerebral infarction and carotid artery stenosis atherosclerotic plaque has a close relationship. Carotid color Doppler ultrasonography as a noninvasive method of examination, early detection of plaques, early treatment, prevention of cerebral infarction.
