Objective:To discuss the relation between ischemic cerebral vascular diseases(ICVD)and carotid ather clerosis(CAS).Methods:206 patients who had ICVD were investigated and classified into transient ischemic attack(TIA)group,and cerebral infarction(CI)group,health screening of 60 patients(control group).The carotid ultrasonicgraphy outcomes,age,gender and the property/locua of atherosclerotic spots were analyzed.Results:(1)The incidence of CAS was significantly higher in CI group than that in TIA group(P<0.05).But the CAS severity among the three groups was of no significance(P>0.05).(2)There was a positive correlation between the incidence of CAS and the increase of age among the three groups(P<0.05),but the severity of CAS had no relation with aging(P>0.05).(3)Solid CAS plaques happened more frequently among ICVD patients(55.06%),whereas loose and composite CAS plaques was much lower(11.80%).(4)Generally,gender had no correlation with CAS.Conclusions:(1)The incidence of CAS was higher in CI group than that in TIA group.(2)Aging affected the incidence of CAS among ICVD patients,but it has no relation with the severity of CAS.(3)Among ICVD patients,most of the CAS was solid plaques.(4)Generally,among ICVD patients,the incident of CAS had no gender difference.
