Background and Purpose—Decisions on invasive arteriovenous malformation (AVM)
treatment are currently based on natural-course risk estimates of AVM bleeding and …

Background: Intracranial hemorrhage is a serious possible complication in patients with
brain arteriovenous malformation (AVM). Several morphologic factors associated with …

Background and Purpose—The morbidity from spontaneous hemorrhage of untreated brain
arteriovenous malformations (AVM) is not well described. Methods—The 241 consecutive …

Background and Purpose—Patients harboring brain arteriovenous malformations (bAVMs)
are at a lifelong risk for hemorrhagic strokes, but the natural history is poorly understood. We …

Background and Purpose—Accurate estimates for risk and rates of intracranial hemorrhage
(ICH) in the natural course of patients harboring brain arteriovenous malformation (BAVM) …

Background A small proportion of strokes are caused by cerebral arteriovenous
malformations (AVM). Treatment to prevent intracranial haemorrhage itself carries risks, and …

Background and Purpose Arteriovenous malformations (AVMs) have an overall 2% to 4%
annual risk of hemorrhage. The purpose of this study was to determine whether specific …

Object The aim of this study was to identify the natural history of untreated cerebral
arteriovenous malformations (AVMs) and the risk factors for subsequent hemorrhage after …

Background and Purpose—The correlation between features present in brain arteriovenous
malformations (AVMs) such as size, location, and angioarchitecture at presentation with …

Objective: To identify risk factors for intracranial hemorrhage in the natural history course of
brain arteriovenous malformations (AVMs) using individual patient data meta-analysis of 4 …
