摘要： 目的观察踝臂指数（ABI）对缺血性脑卒中患者颅内动脉狭窄程度的预测价值。方法测量243例行全脑血管造影的缺血性脑卒中患者的踝臂指数，并收集患者的一般资料。结果以ABI≤0.9作为截断值预测脑供血动脉重度狭窄的特异性为84.6%，敏感性为16.8%。接受者操作特性曲线下面积为（0.591±0.046）(P<0.05), 95%CI=0.500～0.681。结论ABI≤0.9对缺血性脑卒中患者颅内动脉重度狭窄有一定预测价值。

Abstract: ObjectiveTo evaluate the significance of ankler-brachial index (ABI) to predict the extent of intracranial artery stenosis in ischemic stroke patients. Methods243 ischemic stroke patients were enrolled, brain angiography were examined and all of the ABI and basic data were collected. ResultsABI≤0.9 was associated with a specificity of 84.6% and a sensitivity of 16.8% for predicting the presence of severe stenosis in intracranial artery. The area under receiver operating characteristic curve was (0.591±0.046) (P<0.05). ConclusionABI≤0.9 has a relative specificity and sensitivity for predicting the presence of severe stenosis of intracranial artery.
