OBJECTIVE
To evaluate the feasibility, efficacy and safety of a new method for distant injection of Onyx for treatment of intracranial arteriovenous malformations (AVMs).
METHODS
The clinical data of 26 patients with AVMs receiving distant injection of Onyx using the new method were retrospectively analyzed. Onyx was injected by the surgeon in the control room through a pressure transmission system.
RESULTS
The 26 patients received a total of 31 embolization procedures, with an average estimated size reduction of AVMs of (61.48 ± 26.85)%. Total obliteration was achieved in 3 AVMs. In one case, Onyx leakage occurred during the operation resulting from a broken microcatheter, and the patient developed hemiparesis after the operation.
CONCLUSION
Endovascular treatment of intracranial AVMs with Onyx embolization using this new distant injection method is feasible, safe and effective. This method minimizes potential radiation exposure of the surgeons without increasing the risks of related complications.
目的
评估一种新型Onyx远距离注射方法治疗颅内动静脉畸形（AVM）的可行性、有效性及安全性。
方法
回顾性分析26例采用新型方法接受Onyx远距离注射治疗的AVM患者的临床资料。Onyx由外科医生在控制室通过压力传输系统注入。
结果
26例患者共接受31次栓塞手术，AVM平均估计缩小比例为（61.48±26.85）%。3例AVM实现完全闭塞。1例患者手术中因微导管破裂发生Onyx渗漏，术后出现偏瘫。
结论
采用这种新型远距离注射方法，通过Onyx栓塞进行颅内AVM的血管内治疗是可行、安全且有效的。该方法在不增加相关并发症风险的情况下，将外科医生潜在的辐射暴露降至最低。
