目的 探讨颈动脉支架成形术治疗一侧颈动脉重度狭窄对侧颈动脉闭塞患者的安全性和有效性.方法 回顾性分析2008年1月至2016年6月在本科行颈动脉支架成形术治疗的一侧颈动脉重度狭窄对侧闭塞患者的临床和随访资料,总结围手术期处理经验和减少支架治疗并发症的措施.结果 行颈动脉支架治疗的动脉粥样硬化性颈动脉狭窄患者,其中一侧重度狭窄对侧颈动脉闭塞患者21例,本组技术成功率100％,术后30 d内无死亡,无心梗,发生同侧脑梗死1例;2例1年后失访,其余随访22(6～48)个月,无脑卒中,支架内再狭窄1例.结论 颈动脉支架成形术治疗一侧颈动脉重度狭窄对侧闭塞患者是安全、有效的,但需要采取必要措施预防和处理并发症.“,”Objective To explore the safety and effectiveness of carotid artery stenting (CAS) for patients because severe carotid stenosis with contralateral carotid occlusion is high risk factors for carotid endarterectomy (CEA).Methods Clinical data of patients who received carotid artery stenting for severe carotid stenosis with contralateral carotid occlusion in our department were retrospectively collected and analyzed.Results There were 21 patients who received CAS for severe carotid stenosis with contralateral carotid occlusion in our department from Jan 2008 to June 2016.Technical success rate was 100％.There were no myocardial infarction and death but 1 stroke during postoperative 30 days.Nineteen patients were followed-up with a mean time of 22 (6 ～ 48) months and only 1 moderate in stent restenosis were found by duplex ultrasonography.Conclusions Carotid artery stenting is safe and effective for patients who had severe carotid stenosis with contralateral carotid occlusion,but attention should be paid to prevent and manage complications.
