症状性颅内动脉狭窄的支架治疗

目的探讨Wingspan支架治疗症状性颅内动脉狭窄的安全性、可行性和临床疗效。方法应用Wingspan支架治疗90例症状性颅内动脉狭窄患者,观察其手术技术成功率、围手术期并发症,以及术后6个月时脑血管造影显示的支架内再狭窄率。结果 90例患者手术技术成功率约为98.92%(92/93)。术前平均狭窄率为(83.42±9.53)%,术后残余狭窄率为(21.82±9.86)%,手术前后比较差异具有统计学意义(t=3.280,P=0.002)。共5例发生围手术期并发症,约占5.56%(5/90),3例死亡;术后6个月时再狭窄发生率约为19.10%(17/89)。结论 Wingspan支架植入术治疗症状性颅内动脉狭窄具有较高的手术技术成功率、较低的手术并发症及较好的近期疗效,尚待进一步观察患者远期疗效。

Stent treatment of symptomatic intracranial arterial stenosis

Objective To investigate the safety, feasibility and efficacy of the Wingspan stent in treatment of symptomatic intracranial arterial stenosis. Methods Wingspan stenting was applied in 90 cases with symptomatic intracranial arterial stenosis. The surgical success rate and periprocedural neurological complications were observed. Digital subtraction angiography was performed at 6 months after stenting to detect the occurrence of restenosis. Results The technical success rate was 98.92% (92/ 93). Pre treatment stenosis (83.42 ± 9.53)% was improved to (21.82 ± 9.86)% after stent placement. The difference was statistically significant ( t = 3.280, P = 0.002). There were 5 patients (5.56%) occurred major periprocedural neurological complications, 3 of them died within 30 days after the procedure. The restenosis rate at 6 months after operation was 19.10% (17/89). Conclusion Symptomatic intracranial arterial stenosis can be treated by Wingspan stenting with high technical success rate. The occurrence of complication is low and short term efficacy is good. However, further study is needed to investigate long term effect.
