Management of Spinal Dural Arteriovenous Fistulae Using an Interdisciplinary Neuroradiological/Neurosurgical Approach: Experience with 47 Cases

Abstract

Attempts at embolization should be made at the time of angiography, because no adverse effects were recorded in our series and there was a 30% chance of the patients being cured by that modality alone. Even if recanalization occurs, the internal labeling of a feeding vessel with radio-opaque embolization material allows exact intraoperative fluorographic localization of the origin of the draining vein, facilitating minimally invasive surgical exposure.
