Résumé

<p><b>OBJECTIVE</b>To report our clinical experience of using Onyx, a new liquid embolic agent, to treat cerebral arteriovenous malformations (AVMs) as well as its efficacy.</p><p><b>METHODS</b>Seventy cases were placed with 6F sheath in the femoral artery after Seldinger puncture and 6F guiding catheter was introduced into the internal carotid artery or vertebral artery, then a microcatheter was navigated into the nidus of AVMs. Slow injection of Onyx under fluoroscopic control was performed to embolize cerebral AVMs using the "plug and push" technique.</p><p><b>RESULTS</b>Thirteen AVM cases (18.6%) were totally occluded by Onyx and 5 cases of which didn't recurrence at 6-month after operation. Thirty-eight cases (54.3%) were subtotally occluded, while another 19 cases (27.1%) were partially embolized. Severe cerebral hemorrhage occurred in 4 cases, 2 of which had mild to severe hemiplegia after operation, and one died. Mild hemiplegia was also found in 1 case due to functional area embolization, and visual field deficit in 2 cases.</p><p><b>CONCLUSIONS</b>Onyx has unique and distinctive superiority in treating cerebral AVMs. Nonetheless, the correct embolization technique should be learned to achieve good clinical results and avoid complications.</p>
