目的观察Solitaire ab型支架治疗症状性颅内动脉狭窄的安全性及疗效。方法回顾性分析15例药物治疗无效的症状性颅内动脉狭窄病人的临床资料,共发现颅内动脉狭窄16处,其中位于前循环11处,位于后循环5处;均应用Solitaireab支架治疗。结果术前血管狭窄度为60%～99%,平均(78.2±13.8)%,Gateway球囊扩张后残余狭窄度为(31.1±13.5)%,Solitire ab支架植入后残余狭窄度为(25.2±11.6)%,明显低于术前(P<0.05)。结论 Solitaire ab型支架治疗症状性颅内动脉狭窄有较好的安全性和短期临床疗效,但其长期疗效还需进一步研究。
Objective To observe the safety and efficacy of Solitaire ab stent in the treatment of symptomatic intracranial arterial stenosis. Methods The clinical data of 15 patients with symptomatic intracranial arterial stenosis who were ineffective in medical treatment were retrospectively analyzed. There were 16 intracranial arterial stenoses, of which 11 were located in the anterior circulation and 5 in the posterior circulation. All patients were treated with Solitaireab stent. Results The preoperative stenosis was 60% -99% with an average of 78.2 ± 13.8%. The residual stenosis of the balloon was (31.1 ± 13.5)% after balloon angioplasty and the residual stenosis was (25.2 ± 11.6%), which was significantly lower than that before operation (P <0.05). Conclusion The Solitaire ab stent has good safety and short-term clinical efficacy in the treatment of symptomatic intracranial arterial stenosis. However, its long-term efficacy needs further study.
