Association of embolization with long-term outcomes in brain arteriovenous malformations: a propensity score-matched analysis using nationwide multicenter prospective registry data.

ABSTRACT:

Background

Brain arteriovenous malformations (AVMs) account for 25% of hemorrhagic strokes in young adults. Although embolization has been widely performed as a stand-alone procedure to cure brain AVM, it is undermined whether patients benefit from this treatment. This study aimed to compare the long-term outcome of hemorrhagic stroke or death in patients with either conservative management or stand-alone embolization for AVM.

Methods

The study population was derived from a nationwide multicenter prospective collaboration registry (the MATCH registry) between August 2011 and August 2021. The propensity score-matched survival analysis was performed in the overall and stratified AVM cases (unruptured and ruptured), respectively, to compare the long-term outcome of hemorrhagic
