ABSTRACT
Cerebral arteriovenous malformations (AVMs) are uncommon. Treatment options include embolization, radiosurgery and surgery, separately or combined, the final goal being complete occlusion of the malformation. We describe the case of a symptomatic small subependymal AVM with a single deep drainage vein previously treated unsuccessfully by radiosurgery and transarterial embolization. The AVM was successfully embolized transvenously using Onyx, achieving complete occlusion in a single treatment session.

Intracranial dural arteriovenous fistulas with retrograde leptomeningeal or cortical drainage are considered aggressive. Conventional treatment in these cases is possible surgically or with endovascular arterial injections of Onyx or cyanoacrylate, but there are still some cases where distal navigation is not possible due to tortuosity of the arterial feeders. We present five cases of direct transforaminal Onyx embolization where endovascular distal navigation could not be achieved.
