Ruptured arteriovenous malformation mortality: Incidence, risk factors, and inpatient outcome score.

ABSTRACT: BackgroundLimited literature exists on the morbidity and mortality of AVM associated intracerebral hemorrhage (ICH) compared with non-AVM ICH.ObjectiveWe examine morbidity and mortality in cAVM in a large nationwide inpatient sample to create a prognostic inpatient ruptured AVM mortality score.MethodsThis retrospective cohort study from 2008 to 2014 compares outcomes in cAVM related hemorrhages and ICH utilizing the National Inpatient Sample database. Diagnostic codes for ICH and AVM underlying ICH were identified. We compared case fatality according to medical complications. Multivariate analysis was used to derive hazard ratios and 95% confidence intervals to assess odds of mortality.ResultsWe identified 6496 patients with ruptured AVMs comparing them to 627,185 admitted with ICH.
