Abstract: Objective Observe the usefulness of ankle brachial index to predict the extent of intracranial artery stenosis.Methods Ankle brachial index were measured in 243 patients with ischemic cerebrovascular disease received cerebral angiograpathy.Their data including general information, medical history were collected.Results Abnormality of ankle brachial index, plaque of carotid atherosclerosis, history of stroke and age were associated with the number of intracranial artery stenosis in patients with ischemic cerebrovascular disease. Multiple logistic regression analysis showed: age and ankle brachial index were independent risk factors for the number of artery stenosis. Ankle brachial index was negative correlation with the number of intracranial artery stenosis(rs=-0.233, P<0.01). Linear trend analysis showed linear trend between them.Conclusion Ankle brachial index was associated with the number of intracal artery stenosis.

摘要： 目的 观察踝肱指数（ankle brachial index，ABI）对缺血性卒中患者颅内动脉狭窄数量的预测价值。方法 测量243例行脑血管造影的缺血性卒中患者的踝肱指数，并收集其相关临床资料。结果 ABI异常、颈动脉斑块、既往卒中史、年龄与缺血性卒中患者颅内动脉狭窄数量有关。多因素Logistic回归分析结果显示：年龄、ABI是狭窄血管数量的独立预测因子。不同ABI值与颅内动脉狭窄数量之间存在负相关性（rs=-0.233，P＜0.01），线性相关分析显示两者之间存在线性趋势。结论 ABI与颅内动脉狭窄数量有一定的相关性。
