Application of Color Doppler ultrasound in detecting atherosclerotic plaque of caroid artery in elderly patients with cerebral infarction

Objective To explore the clinical value of Color Doppler ultrasound in detecting atherosclerotic plaque of caroid artery in elderly patients with cerebral infarction.Methods Color Doppler ultrasound was used to detect carotid artery intima-medium thickness(IMT),type and morphology of atherosclerotic plaque in patients with cerebral infarction and patients without cerebral infarction.Results Carotid artery plaque was observed in 37 cases(77.09%)in the cerebral infarction group and 10 cases(23.81%) in the control group,the difference had statistical significance(P0.05).The plaque of the cerebral infarction group presented dominantly lipid type with irregular surface.IMT was(1.22±0.31)mm in the cerebral infarction group and(0.68±0.16)mm in the control group,the difference had statistical significance(P0.05).Conclusion Cerebral infarction is related with carotid artery plaque.Color Doppler Ultrasound is a convenient and effective method to investigate carotid artery plaque,which has important clinical value in preventment of the onset of cerebral infarction.
