title: Indocyanine Green Videoangiography in Negative: Spinal Dural Arteriovenous Fistula.
abstract: Introduction This work reports the first indocyanine green videoangiography (IGV) in negative published with video format support. This technique, so called because its first phase is performed with occlusion of the vessel suspected of being pathologic, is used for the diagnosis of spinal arteriovenous fistula (sDAVF). Case Report The authors present the case of a 68-year-old man with an sDAVF fed by the right T7 segmentary artery. IGV was initially performed with the presumptive fistula feeder occluded for less than 1 minute, which provided both diagnostic and postexclusion control in one procedure. This technique therefore is reversible by not prolonging vascular exclusion times. Discussion IGV in negative is an extremely visual and intuitive procedure that represents an improvement over conventional IGV. Conclusion Studies with larger sample sizes are necessary to determine whether IGV in negative can further reduce the need for postoperative digital subtraction angiography.
