OnyX胶远程与常规注射系统栓塞硬脑膜动静脉瘘的疗效对比

Onyx embolization for treatment of dural arteriovenous fistula: comparison of longdistance versus routine injection method

目的比较Onyx胶远程与常规注射系统栓塞硬脑膜动静脉瘘(Dural arteriovenous fistula,DAVF)的疗效、安全性、术者辐射暴露量、注胶时间和注胶量。方法回顾性分析采用Onyx栓塞治疗的59例DAVF的临床资料,分为远程组(28例)和常规组(31例),统计分析比较两组数据的临床特点、术者射线暴露量、注胶量、注胶时间和栓塞效果。结果远程组在术者射线暴露量(P<0.01)较常规组低,两组患者的注胶时间(P=0.53)、注胶量(P=0.78)、供血动脉数(P=0.80)、Cognard分型(P=0.67)、栓塞效果(P=0.88)差异无统计学意义。结论使用Onyx胶远程注射系统栓塞DAVF经初步证实是一种安全可行、能够有效降低术者射线暴露量的方法。

Objective To compare the efficacy, clinical characteristics, safety, injection time and radiation exposure of Onyx embolization using a long- distance injection method and routine injection method for management of dural arteriovenous fistula（DAVF）. Methods The clinical data were retrospectively analyzed in 59 patients with DAVF treated with Onyx embolization using long-distance injection method（28 patients） and routine injection method（31 patients）. The efficacy, safety,injection time and radiation exposure during Onyx embolization were compared between the two injections methods. Results The average radiation dose exposure to the surgeon per procedure was significantly lower in the long-distance injection group than in the routine group. The injection time（P=0.53）, injection volume（P=0.78）, number of supply arteries（P=0.80）, Cognard types（P=0.67）, and effect of embolization（P=0.88） were all similar between the two groups. Conclusion Endovaseular treatment of intracranial DAVF with Onyx embolization using the long-distance injection method is feasible, safe and effective and can reduce the radiation exposure to the surgeon.
