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 ca-rotid artery plaque in patients cerebral infarction and health people. Results In 38 patients cerebral infarc-tion,IMT increase was found in 29 cases and carotid artery plaque was observed in 38 cases(76.3%). In 20 health people,IMT increase was found in 3 cases and carotid artery plaque was observed in 3 cases(15.0%) ,those of two groups were significantly different. 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.
