颅内动脉粥样硬化性狭窄

Intrac ranial atherosclerotic stenosis

颅内动脉粥样硬化性狭窄（intracranial atherosclerotic stenosis，ICAS）是缺血性卒中发生、发展和复发的重要原因，年龄、高血压、糖尿病、吸烟等是其传统危险因素。其中，有症状ICAS是临床干预的重点，治疗方法包括强化药物治疗、血管内介入治疗、颅内外血管旁路移植术、脑硬脑膜动脉联合成形术和体外反搏术等。

Intracranial atherosclerotic stenosis （ICAS） is an important cause for the occurrence, development, and recurrence of ischemic stroke. Age, hypertension, diabetes, and smoking etc. are its traditional risk factors. Among them, symptomatic ICAS is the key of clinical intervention. Its treatments include intensive medical therapy, endovascular treatment, extracranial intracranial arterial bypass grafting, encephaloduroarteriosynangiosis, and external counterpulsation, etc.
