Objective To explore the incidence,distribution and the risk factors of intracranial and extracranial artery stenosis in patients with ischemic cerebrovascular disease(ICVD)in Uygur and Han.Methods Both 165 Han and 108 Uygur patients of ICVD were detected by using DSA.The level of serum glucose and lipidemia were measured.Statistical analysis was used to evaluate the incidence,distribution and risk fators of intracranial and extracranial artery stenosis in Han and Uygur groups.Results 103(62.4%) cases in Han group and 70(64.8%)cases in Uygur group existed intracranial and extracranial artery stenosis,but there was no significantly difference between the two groups.There was no significantly difference in the distribution of cerebral arterial stenosis between Han and Uygur groups.In Han group,age,hypertension,smoking and low HDL were related to cerebral arterial stenosis(P
