Transarterial Onyx Embolization of Intracranial Dural Fistulas: A Prospective Cohort, Systematic Review, and Meta-Analysis.

Background: Onyx is important embolic material in the endovascular treatment of intracranial dural arteriovenous fistula (DAVF). However, its impact on DAVF occlusion rates, morbidity, mortality, and complication rates is not fully examined.

Objective: To improve understanding of safety and effectiveness profiles associated with transarterial endovascular treatment using Onyx for intracranial DAVF.

Dural arteriovenous fistula of the anterior fossa treated with the Onyx liquid embolic system and the Sonic microcatheter.

We report an association of new technologies (the Onyx liquid embolic system and the Sonic microcatheter) for transarterial embolization through the anterior branch of the middle meningeal artery of a dural arteriovenous fistula (DAVF) of the anterior fossa. The place of endovascular treatment in anterior fossa DAVFs is reviewed, and its clinical implications discussed in light of the case of a patient whose management was modified by this association of new technologies.
