目的 探讨血管内栓塞治疗非Galen静脉脑动静脉瘘（NCAVF）的效果.方法 回顾性分析2008年4月至2014年10月收治的16例NCAVF患者（其中北京天坛医院神经介入科14例,陕西省榆林市第二医院神经外科2例）的临床资料,并进行影像学和临床随访.结果 NCAVF患者16例,采用弹簧圈栓塞6例,采用弹簧圈辅助Onyx胶栓塞10例,术后即刻造影示一次完全栓塞瘘口12例,分期完全栓塞2例,近全栓塞2例.术后通过影像学随访3-24个月,复发行二次栓塞治疗1例.临床随访3 -48个月,16例患者症状和体征都得到缓解.结论 弹簧圈或弹簧圈辅助Onyx栓塞治疗非Galen静脉脑动静脉瘘可行,预防并发症,效果良好.对于高流量瘘,弹簧圈可降低血流,辅助Onyx栓塞瘘口.

英文摘要：

Objective To explore the efficacies of embolization in the treatment of nongalenic cerebral arteriovenous fistula （NCAVF）.Methods The clinical data of 16 NCAVF patients （14 from Department of Neurointerventional Medicine,Beijing Tiantan Hospital and 2 from Department of Neurosurgery,Second Municipal Hospital of Yulin） undergoing embolization from April 2008 to October 2014 were analyzed retrospectively.Clinical and imaging follow-ups were conducted.Results Among them,6 patients were embolized with coils alone and the remainder coil plus Onyx glue.The digital subtraction angiography （DSA） images obtained immediately after embolization showed that complete （n =12）,nearcomplete （n =2） and staged （n =2） occlusions of NCAVFs were achieved.One patient recurred during an imaging follow-up period of 3-24 months.All symptoms and signs were relieved after embolization during a clinical follow-up period of 3-38 months.Conclusion Embolization with coil or coil-assisted Onyx embolization is both feasible and efficacious for NCAVF.Using coils helps to reduce the velocity of blood flow and assists Onyx in embolizing fistulas in patients with high-flow NCAVF.
