复杂性椎-基底动脉重度狭窄介入治疗临床分析

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10～20 mm.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.

Clinical evaluation of interventional treatment of severe complicated stenosis of vertebrobasilar system

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...
