目的总结颈动脉狭窄支架成形术的经验,评价其疗效。方法对56例颈动脉狭窄患者在脑保护装置下使用自膨胀支架行颈动脉支架成形术,共放置支架62枚。结果支架释放成功率100%,术后残余狭窄<20%,无死亡病例;4例术后出现低血压,心动过缓,静脉持续给药24 h后恢复正常。结论颈动脉支架成形术是治疗颈动脉狭窄相对安全、有效的方法,远端保护装置的应用是防止术中脑卒中并发症的必要措施。
Objective To summarize the experience of carotid stenosis stenting and evaluate its curative effect. Methods Fifty-six patients with carotid stenosis underwent brachial artery stenting under self-expanding stent under cerebral protection device. A total of 62 stents were placed. Results The successful rate of stent release was 100%, residual stenosis was less than 20% and no death was found. Four patients experienced postoperative hypotension and bradycardia, and returned to normal after 24 hours of continuous intravenous injection. Conclusion Carotid artery stenting is a relatively safe and effective method for the treatment of carotid artery stenosis. The application of distal protection device is necessary to prevent intraoperative stroke complications.
