摘　　要：[目的]总结分析颈动脉狭窄支架置入术中各种并发症发生的原因与防治对策.[方法]对34例颈动脉狭窄＞70%的患者,予以支架置入治疗,并在术中术后严密观察其并发症的发生,同时在支架置入时使用脑保护器.[结果]34例患者共置入35枚支架.手术成功率100%,支架形态良好.有2例术中出现一过性意识障碍,支架置入术后患者动静脉循环时间为3.23 s,说明术后患者脑动、静脉循环时间大为改善,24例临床症状完全消失.8例肢体轻度活动受限,2例吐词不清较前好转.[结论]血管内支架成型术(CAS)对于颈动脉狭窄的治疗是有效的.从治疗即刻效果看,能使狭窄管腔重新塑型扩张,改善了血流状态.术后观察2～20个月无一例再狭窄发生.与颈动脉内膜剥离术比,它有创伤小、痛苦轻、成功率高、并发症少等优点,是治疗颈动脉狭窄最有前景的好方法.但远期疗效还值得进一步追踪随访.[Objective]To study what complications would appear and how to prevent them in treatment of carotid artery stenosis by stent placement, [Methods]Thirty-four patients of carotid artery stenosis （ the stenosis extent〉70%） were treated by stent placement and cerebral protection, the complications in surgery and after surgery observed. [Results]Thirty-five stents were released in 34 cases.the rate of success was 100%. The shape of stent was good. No artery stenosis recurrence was observed 2-20 months after stenting. [Conclusion] For carotid artery stenosis, stent placement is an effectual way. It can make artery stenosis reexpand and improve blood flow. Compared with endarterectomy, stent placement has a lot of exeellences, such as mininal invasion and pain, high ratio of success and few complications etc. It is a good way to treat carotid artery stenosis.
