目的：分析总结血管内支架置入术治疗颅外段血管狭窄的疗效及安全性。方法经颈部超声检查、M RA及全脑血管造影筛选出颈动脉或椎动脉及锁骨下动脉狭窄患者16例，行血管内支架置入术，其中颈动脉支架处共放置10枚，椎动脉及锁骨下动脉支架共放置10枚。结果16例患者手术成功，成功率100％，术中1例出现轻度脑血管痉挛，2例出现颈动脉窦综合征，1例出现高灌注综合征。术中未出现微栓子脱落致卒中。影像学上动脉狭窄得到有效改善，临床缺血症状术后得到明显改善，短期随访6个月，未出现支架植入同侧短暂性脑缺血发作和新发脑梗死，无支架置入血管内再狭窄病例。结论在严格掌握适应证和有经验的医生操作下，颅外段动脉支架植入术是治疗动脉狭窄安全、有效的方法，是预防缺血性脑卒中的新选择。

Objective To evaluate the effect and security of endovascular stent placement for the treatment of extracranial artery stenosis. Methods Methods 16 patients with extracranial artery stenosis were screened out by ultrasound ,MRA and digital subtraction angiography ,then were treated with endovascular stent placement. Among them ,10 stents were placed in carotid arteries ,10 stents were implanted in vertebral arteries and subclavian arteries.Results All the operations were success-fully made. Among them ,mild cerebral vasospasm happened in 1 patient. The Carotid sinus syndrome occurred in 2 patients.1 patient had a high perfusion syndrome. None of the patients had Micro embolic loss during the procedures. All clinical ischemia signs were improved remarkably. DSA showed that the diameter of stenosed segment of artery was markedly enlarged. There were no transient ischemic attack and cerebral infarction on the ipsilateral side in the following six month. During the period of follow-up ,there were no patient afflicted with recurrent narrow of artery tested by ultrasonic examination.Conclusion On ba-ses of clear indications and sophisticated skill ,the endovascular stenting is an effective and safe treatment for extracranial artery stenosis ,so it is a new choice for prevention of ischemic cerebral stroke.
