症状性颅内动脉狭窄区域发生缺血性脑卒中的预测危险因素

Predictors of ischemic stroke in the territory of a symptomatic intracranial arterial stenosis

背景：华法令一阿司匹林治疗症状性颅内动脉疾病比较研究（WASID）最近评价了颅内动脉狭窄溶栓治疗的疗效。WASID研究的主要目的是明确颅内动脉狭窄区域发生脑卒中的高危因素，为随后开展的颅内动脉支架植入及内科治疗比较研究奠定基础。

BACKGROUND： Antithrombotic therapy for intracranial arterial stenosis was recently evaluated in the Warfarin versus Aspirin for Symptomatic Intracranial Disease （WASID） trial. A prespecified aim of WASID was to identify patients at highest risk for stroke in the territory of the stenotic artery who would be the target group for asubsequent trial comparing intracranial stenting with medical therapy.
