液体栓塞剂Onyx在脑动静脉畸形治疗中的探索

Liquid embolic agent Onyx in the treatment of cerebral arteriovenous malformations

目的：探讨应用液态栓塞剂Onyx栓塞治疗脑动静脉畸形（AVM）的技术方法和临床意义。方法：在全麻下采用Onyx对8例脑AVM进行血管内栓塞，反复使用路图观察Onyx流动方向，用DSA方法评估栓塞效果。结果：一次性栓塞畸形血管面积达95％1例，70％以上3例，30-70％4例。术后并发出血l例，微导管留置1例。结论：Onyx有可控性好、一次栓塞的畸形团多等优点，有助于脑AVM的治疗。

Objective： To explore the clinical significance of a liquid embolic agent Onyx in the treatment of cerebral arteriovenous malformations （AVMs）. Methods： 8 cases of cerebral AVMs were embolizod with Onyx. The embolic effect was determined by using DSA method. Results： The embolie area was more than 95% in 1 case, more than 70% in 3 eases, and less than 70% in 4 eases. Hemorrhagic complication occurred in 1 case, and microeatheter remained in 1 case. Conclusion： Onyx has the advantages of good controllability and successful embolism with a single injection, ant it is one of the reliable and effective approaches to treating AVMs.
