目的　报告球囊闭塞椎动脉治疗椎 -基底动脉瘤的情况。方法　局麻下股动脉插管 ,在球囊闭塞 (Ma-ta,s)试验成功后 ,闭塞小脑后下 (PICA)开口近端的椎动脉。结果　成功闭塞 5例椎动脉 ,无并发症。结论　球囊闭塞椎动脉治疗椎 -基底动脉 ,尤其是梭形、囊状巨大动脉瘤简捷、安全、效果好 ,实施控制性抗凝有助于防止缺血的发生 Objective To report the treatment of vertebral-basal aneurysms by occlusion of the vertebral artery with a balloon. Methods The femoral artery was cannulated under local anesthesia. After successful balloon occlusion (Ma-ta, s), the vertebral artery proximal to the opening of the cerebellum (PICA) was occluded. Results Successful occlusion of 5 vertebral arteries without complications. Conclusion Balloon occlusion of vertebral artery for the treatment of vertebral-basal arteries, especially fusiform cystic giant aneurysms, is simple, safe and effective. The implementation of controlled anticoagulation can help prevent the occurrence of ischemia.
