Embolization of arteriovenous malformations (AVMs) is commonly used to achieve nidal volume reduction before surgical extirpation and stereotactic radiosurgery. Two commonly used liquid embolics are N-butyl cyanoacrylate (NBCA) and OnyxTM. OnyxTM is a nonadhesive agent with longer polymerization time leading to better penetration of the nidus compared with NBCA. In our department, 20 patients with AVMs were treated with OnyxTM. 16 patients underwent a surgical resection, and 3 underwent radiosurgical treatment. Angiographically, more than 75% obliteration was achieved in 16 patients (80%). Procedure-related permanent neurological deficits were observed in 3 patients. OnyxTM embolization is a safe and effective treatment for AVMs.
