Study on carotid lesion in cerebral infarction cases by color Doppler ultrasonography

Objective To explore if there is relationship between carotid lesions and cerebral infarction in elderly and attempt to screen out the indexes of carotid lesions related to cerebral infarction. Methods Color Doppler ultrasonography was applied to 51 cases of cerebral infarction group and 25 cases of non-cerebral infarction group.The intima-media thickness(IMT),the degree of stenosis,carotid plaque and the index of change in the blood flow status of bilateral common carotid arteries and internal carotid arteries were examined.Results The IMT of common carotid arteries,the detection rate of carotid plaque,the plaque scores and the rate of soft and compound plaques in the infarction group were significantly higher than those in the control group. The end diastolic velocities in the common carotid and internal carotid arteries were lower in the infarction group than in the control group. Conclusion It was likely to have relationship between carotid lesions and cerebral infarction. The IMT,the rate of the soft and compound plaques and the end diastolic velocity were valuable indexes of carotid lesions related to cerebral infarction.
