摘要
目的探讨支架置入血管成形术治疗复杂性椎-基底动脉狭窄的可行性、安全性及疗效。方法2003年11月至2007年12月对5例复杂性多发椎-基底动脉重度狭窄患者进行了支架置入血管成形术治疗。结果5例患者中,一侧椎动脉闭塞4例,另1例双侧椎动脉起始部重度狭窄。治疗侧椎动脉起始部重度狭窄合并椎动脉颅内段及基底动脉狭窄4例,另1例椎动脉颅内段及基底动脉多发重度狭窄。狭窄率80%～95%,狭窄段长度10～20mm。支架植入手术全部成功,血管残余狭窄均小于20%,技术成功率为100%。术后全部患者椎-基底动脉供血不足症状均消失。本组5例患者术后6～12个月分别行DSA检查随访,均未发现再狭窄,近期疗效满意。结论支架置入血管成形术是治疗椎-基底动脉供血不足,预防椎-基底动脉系统卒中的安全、有效方法,近期预后良好。
Objective To evaluate the feasibility, safety and efficacy of percutaneous transluminal stenting angioplasty for severe complicated stenosis of vertebrobasilar system. Methods＇ From November 2003 to February 2006, 5 candidates underwent percutaneous transluminal stenting for severe complicated stenosis of vertebrobasilar system. Results Four out of 5 candidates, had occlusion of unilateral vertebral artery （VA）, 1 had severe bilateral proximal segmental stenosis of VA. There were 4 with severe proximal segmental stenosis of the VA associated with multiple segmental stenosis of intracranial VA and basilar artery （BA）, and 1 with multiple segmental severe stenosis of intracranial VA and BA. Stenosis rate ranges from 80% -95% with involved length from 10-20 mm. Technical success was achieved in all of the patient （100%）, and residual stenosis rate was less than 20%. All the symptoms due to vertebrobasilar blood supply insufficiency disappeared. Follow-up with DSA 6-12 months later demonstrated no restenosis; showing satisfactory short term efficacy. Conclusions Percutaneous transluminal stenting for vertebrobasilar blood supply insufficiency is a safe and efficacious option with favorable short term outcome, especially with furthermore prevention of stroke.
