Solitarie支架在颅内动脉硬化性狭窄治疗中的应用

Application of solitaire stents in treatment of intracranial arterial atherosclerotic stenosis

目的探求Solitaire自膨支架对颅内动脉狭窄疗效的可行性。方法回顾总结5例颅内动脉狭窄患者,实施球囊扩张Solitaire支架成形术,共留置支架6枚。病变部位位于大脑中动脉M1段3例,基底动脉段1例,颈内动脉前床突段1例;病变长度为(8±2.9)mm,狭窄率为(73±8.5)%。结果手术成功率100%,术后残余狭窄率为(14±4.2)%。DSA随访平均时间10.5个月,无支架内再狭窄发生;1例患者术后出现患侧TIA发作两次。结论使用Solitaire自膨支架可以对颅内重度狭窄病变行支架成形术具有一定可行性,但需更进一步研究。

Objective To explore the feasibility o f Solitaire self-expanding stent in the treatment of intracranial arterial stenosis. Methods Five patients with intracranial arterial atherosclerotic stenosis were reviewed, in whom angioplasty with solitaire stents were performed, and a total of 6 stents were placed. Lesions located in the middle cerebral artery Ml segment in 3 cases, basilar artery segment in 1 case, and internal artery C2 segment in 1 case. The length of lesion was （8＋2.9）mm, the stenosis rate was （73＋8.5）%. Results All patients were received Solitaire stents implanation successfully. Residual stenosis rate was （14＋4.2）%. The mean follow-up time of DSA was 10.5 months, no stent restenosis occurred. Twice transient ischemia attack were happened in 1 patient. Conclusions The use of Solitaire self-expanding stent could be feasibility for angioplasty for severe intracraoial stenosis, but it needs further study.
