目的探讨NBCA栓塞治疗脑动静脉畸形(AVM)的并发症的发生率及高危因素。方法回顾性研究469例施行NBCA栓塞治疗的脑AVM的临床和影像学资料,总结并发症的情况以及分析他们的血管构筑学特征。结果469例脑AVM共行1108次栓塞,每例栓塞1~8次,平均2.3次;共发生并发症11例(出血性并发症4例,缺血性并发症7例),其中死亡2例,植物生存1例,轻度永久性神经功能缺损1例,短暂性神经功能缺损7例。结论本组脑AVM行NBCA栓塞治疗有较低的手术相关并发症。但对于栓塞高危病人,应采取特殊的栓塞策略。
Objective To investigate the incidence and risk factors of NBCA embolization in the treatment of cerebral arteriovenous malformations (AVM). Methods The clinical and imaging data of 469 brain AVMs embolized with NBCA embolization were retrospectively reviewed. The complications and their vascular architecture were analyzed retrospectively. Results A total of 1,108 embolizations were performed in 469 patients with AVM, with an average of 2.3 times per embolus. There were 11 complications (4 with hemorrhagic complications and 7 with ischemic complications), of which 2 died , 1 case of plant survival, 1 case of mild permanent neurological deficit and 7 cases of transient neurological deficit. Conclusions NBCA embolization with AVM in this group has lower surgical complications. However, high-risk patients with embolism should take a special embolization strategy.
