摘要
目的研究MO.MA球囊保护下颈动脉支架成形术(CAS)治疗近闭塞颈动脉的安全性、可行性及疗效。方法 2006年至2010年,共收治14例近闭塞颈动脉患者,狭窄程度95%～99%,所有病例可见侧支代偿。其中表现为短暂性脑缺血发作(TIA)者11例,表现为脑血栓形成者3例。所有患者均在MO.MA球囊保护下行CAS。对手术成功率、围手术期并发症、随访结果进行分析。结果手术成功率为100%。围手术期并发症2例,术中出现TTA发作,2 h后恢复正常。对患者进行随访3～30个月,平均(10.7±7.7)个月。4例行CTA或DSA随访,无再狭窄发生,无病变侧颈动脉脑卒中发生。结论 MO.MA球囊保护下CAS治疗近闭塞颈动脉安全、有效,无法耐受颈动脉血流阻断是主要的风险。
Objective To assess the safety, feasibility and efficacy of carotid artery stenting （CAS） with the use of MO.MA proximal cerebral protection device for the treatment of nearly-occluded carotid artery. Methods During the period from 2006 to 2010, a total of 14 patients with nearly-occluded carotid artery （stenosis degree of 95% - 99%） were treated with CAS. The signs of collateral circulation were observed in all patients. The disease presented as transient insufficiency attack （TIA） in 11 patients and was manifested as cerebral thrombosis in 3 patients. CAS procedure was performed with the use of MO.MA proximal cerebral protection device in all patients. The success rate, perioperative complications and follow-up results were recorded and analyzed. Results The technical success rate was 100%. TIA occurred in two patients and the patients recovered two hours later. All the patients were followed up for 3 - 30 months with a mean of （10.7 _＋ 7.7） months. Follow-up CTA or I）SA after CAS was performed in 4 cases, and no re-stenosis was observed. No ipsilateral stroke occurred during the follow-up period. Conclusion Carotid artery stenting with the use of MO.MA proximal cerebral protection device is a safe and effective therapeutic option for nearly- occluded carotid artery. Neurologic intolerance to carotid flow blockage is the main risk of this technique. （J Intervent Radiol, 2012, 21： 447-450）
