症状性颅内动脉狭窄支架治疗的研究现状

Current research progress of stent therapy for symptomatic intracranial arterial stenosis

颅内动脉狭窄(IAS)是缺血性脑卒中(IS)发病的一个重要原因,针对亚洲人种,有研究发现颅内动脉狭窄的发生率是颅外动脉狭窄发生率的2倍。目前治疗症状性颅内动脉狭窄仍然是临床上的难点,药物治疗至今仍未取得令人满意的效果,尤其是重度颅内动脉狭窄。近年来随着技术和材料的发展,血管内支架治疗症状性颅内动脉狭窄已逐渐成为一种相对安全有效的新途径,亦是一项仍需不断改进和发展的新技术。

Intracranial arterial stenosis （IAS） is an important cause of ischemic stroke （IS）. Studies of morbidity for the Asian race have found that the incidence of intracranial arterial stenosis is twice than that of the extracranial arterial stenosis. The treatment of symptomatic intracranial artery stenosis remains difficult. Drug therapy has not yet achieved satisfactory results especially in severe intracranial arterial stenosis. In recent years, with technology and material＇s development, vascular stent for symptomatic intracranial arterial stenosis has become a relatively safe and effective new way, but continuous improvements and develovment of this new teehnologies are needed.
