Embolization of Arteriovenous Malformations with Onyx: Clinicopathological Experience in 23 Patients

Abstract

Onyx is a new nonadhesive liquid embolic agent that has been used to treat 23 patients at our institution with good results. Its nonadhesive nature and ease of use make it a promising agent in the future treatment of AVMs.

The use of Onyx for embolization of peripheral vascular malformations in pediatric patients

“…Previous articles about peripheral use of Onyx as an embolic agent have been limited to smaller series of patients [7,[33][34][35][36], but the success of Onyx in the treatment of cerebral AVMs [37][38][39] suggests that this agent may also prove to be effective in the treatment of peripheral VMs. The current study is the only series to date regarding peripheral VMs in pediatric patients.…”

Superselective arterial embolisation with a liquid polyvinyl alcohol copolymer in patients with acute gastrointestinal haemorrhage

“…Recently published data showed favourable results in the treatment of cerebral and spinal arteriovenous malformations (AVM) and cerebral aneurysms with Onyx® without major complications [13][14][15]. Neurointerventionalists appreciate the advantage of Onyx® over NBCA with its reduced risk of gluing the catheter to the vessel wall.…”

Pathophysiology and Treatment of Brain AVMs*

“…Overall, the results of recent reports seem to indicate that curative embolization of brain AVMs in multiple sessions can achieve higher rates of total and near-total occlusion with acceptable rates of morbidity and mortality [48][49][50].…”
