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 comp
