Background: Hemorrhage from cerebral dural arteriovenous fistulae (dAVF) is a considerable source of neurologic morbidity and even mortality.
Objective: To evaluate the natural history of cerebral dAVF.
Methods: We reviewed our own cohort of 70 dAVF and incorporated results from the literature, synthesizing pooled hemorrhage rates and evaluating risk factors for 395 dAVF in 6 studies.

BACKGROUND: The quoted risk of hemorrhage from dural arteriovenous fistulae with cortical venous reflux varies widely, and the influence of angiographic grade on clinical course has not previously been reported.
OBJECTIVE: To assess the risk of hemorrhage and the influence of angiographic grade on this, compared to known predictors of hemorrhage such as presentation.
METHODS: 75 fistulae with cortical venous reflux identified in our AVM clinic between 1992 and 2007 were followed up clinically, and their angiograms reviewed.
