Indocyanine Green Videoangiography “In Negative”

Abstract

IGV-IN is an improvement over the conventional IGV method and is able to provide more information in a shorter period of time. It is an intuitive and highly visual procedure, and, more importantly, it is reversible. Studies with larger samples are necessary to determine whether IGV-IN can further reduce the need for postoperative digital subtraction angiography.

Indocyanine Green Videoangiography in Negative: Spinal Dural Arteriovenous Fistula

“…IGV in negative has been developed for the diagnosis of spinal and intracranial dural arteriovenous fistulae. 1 2 Conventional IGV involves the intravenous administration of indocyanine green. Subsequently, vascular filling is visualized using specific optical systems that are integrated in current surgical microscopes.…”

“…Indocyanine green videoangiography (IGV) in negative, so called because its first phase is performed with occlusion of the vessel suspected of being pathological, has been defined in spinal and intracranial dural arteriovenous fistula. 1 2 In the present work, the authors show the first case of IGV in negative published with video support, which was used for the diagnosis of a spinal arteriovenous fistula (sDAVF). This procedure avoids some of the limitations of conventional IGV and facilitates its interpretation.…”

Neurosurgery for Cranial Dural Arteriovenous Fistulas

“…Indocyanine green (ICG) videoangiography can be useful in assessing successful DAVF disconnection intraoperatively (Hanggi et al 2010). The immediate availability of ICG and essentially instantaneous results make it a valuable adjunct which continues to be modified and improved (Simal Julian et al 2013). Future developments may make it possible to detect intraoperative differences in tissue perfusion after disconnection of a fistula and thus confirm normalization of venous pressure (Shidoh et al 2013).…”
