Long-term outcomes after treatment for symptomatic hemorrhage of brain arteriovenous malformations.

ABSTRACT:

Objectives

To determine the long-term risk factors for rehemorrhage (primary outcome) in patients with ruptured brain arteriovenous malformations (BAVMs) after different treatment strategies and to evaluate the impact of different treatment strategies on lesion obliteration (secondary outcome) over a 10-year follow-up.

Methods

This single-center retrospective cohort included 645 patients with ruptured brain arteriovenous malformations (BAVMs) treated between 2010 and 2019, with a median follow-up of 96 months. Patients were randomly divided into training (70%) and validation (30%) cohorts to identify and validate predictors of rehemorrhage-free survival (RFS). Cox regression analyses were performed to assess risk factors for RFS, while logistic regression and propensity scor
