Risk factors for flow-related aneurysm rupture associated with posterior circulation arteriovenous malformation: a multicenter retrospective study.

ABSTRACT:

Background

Flow-related aneurysms (FAs) are more common and have an increased risk of rupture in posterior circulation arteriovenous malformations (pAVMs). However, the risk factors for FA rupture in pAVMs are understudied and warrant further investigation.

Objective

This study aimed to investigate the risk factors for FA rupture associated with pAVMs using a multi-centric database from 1 January 2020 to 31 December 2024.

Methods

Patients diagnosed with AVMs were selected from databases. Patients with ruptured FAs and those with unruptured FAs were compared. Independent Student's t-test, Mann-Whitney U-test, Fisher's exact test, and multivariable binary logistic regression were used for analysis.

Results

Among 284 patients, 37 patients with 22 rup
