彩超检测颈动脉粥样硬化与脑梗死的关系

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101例脑梗死患者63例颈总动脉IMT增厚，颈动脉粥样硬化斑块检出率为84．2％；40例非脑梗死者6例颈总动脉IMT增厚．粥样硬化斑块检出率为32．5％，两组有显著差异（P〈0．001）。结论脑梗死的发生与颈动脉粥样硬化斑块有密切关系。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，对临床预防脑梗死有重要的意义。

Analysis on correlation of carotid artery atherosclerosis and cerebral infarction by Color Doppler Flow imaging

Objective To analysis 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.Results In 101 patients with cerebral infarction,IMT increase was found in 63 cases and carotid artery plaque was observed in 85 cases(84.2%). In 40 patients without cerebral infarction,IMT increase was found in 6 cases and carotid artery plaque was observed in 13 cases(32.5%), those of Two groups were different significantly. Conclusion Cerebral infarction is related with carotid artery plaque.Color Doppler Flow Ultrasound is a convenient and effective method to investigate carotid artery plaque,which is important to prevent the onset of cerebral infarction.
