|Other Abstract||Objective: To investigate the distribution characteristics and severity of cerebral artery stenosis in patients with ischemic cerebrovascular disease (ICVD),ischemic cerebrovascular disease risk factors and common sense to open collateral circulation ischemic cerebrovascular disease.
Methord: The data of cerebral angiography in 261 patients with ischemic cerebrovascular disease who performed cerebral angiography were analyzed retrospectively.They were divided into young (aged 6-44 years), middle-aged (aged 45-59 years), and elderly (aged ≧60 years) groups according to their ages.
Results: 70.11% patients had cerebral artery stenosis or occlusion, and 29.89% patients had no cerebral artery stenosis. Intracranial artery stenosis was 40.98%， extracranial artery stenosis was 32.79% , and extra-and intracranial artery stenosis was 26.23%. (1)、The proportion of intracranial artery stenosis in the young group (71.43%) was significantly higher than that in the middle-aged group (33.93% ，P<0.01) and that in the elderly group (26.92%，P<0.01). The proportion of extra-and intracranial artery stenosis in the elderly group (37.18%) was significantly higher than that in the young group (16.33%，P<0.05) and that in the middle-aged group (19.64%，P<0.05). (2)、In the 261 cases , 325 lesions were found, including 237 stenoses and 88 occlusions. The proportion of occlusions in the young group (39.77%) was significantly higher than that in the middle-aged group (19.63%，P<0.01) and that in the elderly group (22.38%，P<0.01). (3)、The patients with cerebral infarction were 117, and the proportion of intracranial artery stenosis was 36.75%, while extracranial artery stenosis was 35.90% , and the extra-and intracranial artery stenosis was 27.35%. The patients with transient ischemic attack (TIA) were 66, and the proportion of intracranial artery stenosis was 48.49%, while extracranial artery stenosis was 27.27% , and the extra-and Intracranial artery stenosis was 24.24%；there are no significant difference between two groups in the distribution of vascular stenosis (P>0.05). (4)、In cerebral infarction group 220 lesions were found, and the proportion of mild-moderate stenosis was 44.09%, while severe stenosis was 26.36%, and the occlusions was 29.55%. In TIA group 105 lesions were found, and the proportion of mild-moderate stenosis was 66.67%, while severe stenosis was 11.43%, and the occlusions was 21.90% . The difference of sevetity of artery stenosis between TIA grou...|
