Apollo支架治疗颅内椎基底动脉狭窄的初步临床研究

目的探讨和总结Apollo支架治疗颅内椎基底动脉狭窄的技术及疗效。方法对12例颅内椎基底动脉狭窄者使用Apollo支架行支架成形术治疗,其中椎动脉颅内段狭窄7例,基底动脉狭窄5例,病变狭窄程度均〉70%,狭窄长度2-15mm。结果12例全部技术成功,共放置支架14枚,病变残余狭窄≤20%。在围手术期内无严重并发症发生。术后临床短期随访3-10个月,临床症状消失10例,明显改善2例,全部患者无脑缺血性事件发生;其中DSA随访5例无支架狭窄。结论运用Apollo支架治疗颅内椎基底动脉狭窄是一种安全有效的方法,但其长期疗效仍需进一步观察。

Preliminary clinical in vestigation of Apollo stent for the treatment of intracranial vertebrobasilar arterial stenosis

Objective To insvestigate and summarize the technique and efficacy of angioplasty with Apollo stent for the treatment of intracranial vertebrobasilar arterial stenosis. Methods Twelve cases of intracranial vertebrobasilar arterial stenosis received angioplasty and stenting with Apollo stent. The locations of stenoses were intracranial segment of vertebral artery in 7 and basilar artery in 5. All stenoses were more than 70% in diameter, with 2 - 15mm in length. Results The treatment succeeded in all 12 cases 14 sents were successfully implanted, without any serious complication. All the residual degrees of stenosis after stenting were less than 20%. Clinical symptoms disappeared in 10 patients, relieved in 2 patients. There were no symptom related to thrombosis occurred during clinic short-up for 3 to 10 months after stenting. Follow-up angiogram in 5 eases showed no stenosis in segment of the stentt. Conclusion Angioplasty and stenting with Apollo stent are safe and effective for treating intracranial ver- tebrobasilar stenosis. The long term outcome sill needs to be investigated further.
