OBJECTIVE: To review the experience with Onyx embolisation of cerebral arteriovenous malformation.
DESIGN: Prospective study.
SETTING: A regional neurosurgical centre in Hong Kong.
PATIENTS: Data of patients with cerebral arteriovenous malformation who underwent Onyx embolisation over a 14-month period were prospectively collected.
RESULTS: Eleven sessions of Onyx embolisation were performed in nine patients with cerebral arteriovenous malformations, seven of which had ruptured. Total occlusion was achieved in three (33%) of the patients, and subtotal occlusion (over 80% occlusion) in three out of four with Spetzler-Martin grade-III/IV malformations. One patient developed mild permanent neurological deficit.
CONCLUSION: Onyx embolisation of cerebral arteriovenous malformations is feasible in Hong Kong. Careful patient and target selection are important
