应用Onyx栓塞脑动静脉畸形

Using Onyx Embolization of Cerebral Arteriovenous Malformations

目的探讨应用Onyx栓塞系统治疗脑动静脉畸形的手术操作与安全性。方法应用Onyx栓塞系统治疗9例脑动静脉畸形,分析介入手术栓塞操作相关注意事项。结果7例患者中栓塞后畸形血管团完全消失1例,消失80%以上4例,50%-80%之间2例。术后发生一过性肢体麻木者1例,24h内继发出血1例。结论术前仔细研究病灶血管构筑,制定栓塞方案,术中耐心操作,应用Onyx栓塞脑动静脉畸形较为安全、畸形血管团栓塞率较高。

Objective To study interventional procedure and safety of embolization of cerebral artenovenous malformations（AVMs） with Onyx. Methods Application of Onyx embolization system in the treatment of 7 cases of cerebral arterionvenous malformations, surgical intervention of attention to matters related to operation of embolism. Results 7 ceses of The AVMs nidus are 100% embolized in 1 cese, 〉 80% 4 ceses, 50 - 80% 2 ceses. One patient has paraesthesia on limb, the symptoms disappear 5 days. Intracranial hemorrhage was found in 1 case within 24 hours after the procedure. Conclusion study the Angioarchitecture carefully, keep patient all the interventional procedure. Embolization of AYMs with Onyx is safety and efficacy.
