The distribution of cerebral artery stenosis in patients with ischemic cerebrovascular disease

Objective To explore the distribution of cerebral artery stenosis in patients with ischemic cerebrovascular disease of different ages.Methods 340 adult patients with ischemic cerebrovascular disease detected by angiography had cerebral artery stenosis.They were divided into cerebral infarction(CI)group and transient ischemic attack(TIA)group,and were also divided into the young-aged group,middle-aged group and old-aged group.Results The rates of smoking and drinking alcohol in cerebral infarction patients were higher than those in TIA patients(P0.05).The incidence rates of carotid artery stenosis and extracranial artery stenosis in old-aged group were higher than those in middle-aged group and the young-aged group(P0.05).The frequency of intracranial artery stenosis was higher than that of extracranial artery stenosis in the young-aged group.In contrast,the frequency of extracranial artery stenosis was higher than that of intracranial artery stenosis in the old-aged group.The frequency of anterior circulation artery stenosis was higher than that of the posterior circulation artery stenosis in ischemic cerebrovascular disease patients and CI patients(P0.01).The frequency of the whole circulation and the posterior circulation artery stenosis in the old-aged group was higher than that in the middle-aged group and the young-aged group(P0.01).The frequency of the whole cirulation and the posterior circulation artery stenosis in the middle-aged group was higher than that in the young group(P0.01).Conclusion The distribution of cerebral artery stenosis varies with disease and age.
