Early Experience of Indocyanine Green Videoangiography in Cerebrovascular Surgery

Abstract

Fluorescence angiography was first used by ophthalmologists to measure retinal blood flow by using the fluorescent dye fluorescein. With the use of indocyanine green (ICG) as a novel fluorescent dye, and its integration into a compact system that takes advantage of modern video technology, fluorescence angiography has recently re-emerged as a viable option. We present representative cases of which ICG videoangiography is useful in the treatment to show the efficacy of ICG videoangiography in cerebrovascular surgery. ICG videoangiography is a safe and simple method with which to assess the microcirculation of the brain.
