Abstract: Objective To study the distribution and evolution of cerebral artery stenosis in ischemiccerebrovascular patients.Methods Two hundred and thirty patients with ischemic cerebrovascular disease were detected bycerebral angiography. They were divided into <60 years old group and ≥60 years old group, thencomparing the differences of cerebral arteries stenosis between the two groups.Results The percentage of extracranial carotid arteries stenosis and extracranial arteries stenosis inposterior circulation in ≥60 years old group were higher than those in <60 years old group(P <0.01).The occlusion of intracranial arteries in <60 years old group was more frequent than those in ≥60years old group(P <0.01), and in <60 years old group, it was more frequent than the occlusion ofextracranial arteries(P <0.01).Conclusion The distribution of cerebral artery stenosis varies with age, and the evolution areaffected by the distribution and age.
