颈部动脉粥样硬化的彩超检查及其与脑梗死相关性探讨

目的探讨颈动脉粥样硬化与脑梗死的关系。方法使用彩色多普勒超声检测脑梗死患者及非脑梗死患者颈动脉内膜厚度(IMT)及粥样硬化斑块。结果 224例脑梗死患者中检出颈动脉硬化196例(87.5%);60例非脑梗死患者中检出颈动脉硬化10例(16.7%),两者比较差异有统计学意义(χ2=119.188,P<0.05)。结论脑梗死的发生与颈动脉粥样硬化有密切关系。彩色多普勒超声是检测颈动脉粥样硬化斑块简捷的方法,对脑梗死预警和防治具有重要价值。

Analysis on correlation of carotid artery atherosclerosis and cerebral infarction by color doppler flow imaging

Objective To analyze the relationship of carotid artery atherosclerosis and cerebral infarction. Methods Color Doppler flow imaging was used to investigate carotid artery intima-medium thickness （IMT） and carotid artery plaque in patients with cerebral infarction and patients without cerebral infarction. The age and gender of both groups had no significant difference. Results In 224 patients with cerebral infarction, cerebral infarction was found in 196 cases （87.5%）, in 60 patients without cerebral infarction, cerebral infarction was found in 10 cases （16.7%）, and those of both groups were significantly different （χ^2=119.188, P 〈 0.05）. Conclusion Cerebral infarction is closely related with carotid artery atherosclerosis. Color Doppler flow ultrasound is a convenient and effective method to investigate carotid artery atherosclerosis, which is important to prevent the onset of cerebral infarction.
