Ultrasonographic study on carotid atherosclerosis in patients with cerebral infarction

Objective To study the relationship between carotid athrosclerosis(CAS) and cerebral infarction with ultrasonography. Methods The quantifiation of intima-medium thickness(IMT),identification of plaques, systolic peak velocity(SPV) and end diastolic velocity(EDV) of the bilateral carotid artery were detected by ultrasonography. Results The mean intima-medium thickness(IMT) in patients with cerebral infarction was significantly increased than that of the control group(P0.01). In the cerebral infarction group,92 plaques(79.3%) were observed,while only 37 plaques(46.3%) were found out in the control group. The systlic peak velocity and end diastolic velocity were significantly increased in the bilateral carotid artery of patients with cerebral infarction than those of the control group(P0.01). Conclusion CAS and cerebral infarction are closely related.CAS can be diagnosed in patients with cerebral infarction,which is important to forecast the onset of cerebral infarction.
