Intraoperative Evaluations of Microscope-integrated Videoangiography Using Indocyanine Green for Cerebrovascular Operations

Abstract

In the present study, we assess whether a new technique of surgical microscope-based videoangiography (VAG) using indocyanine green (ICG) is suitable for confirming a patent extracranial-intracranial bypass or a complete aneurysmal clipping. We also describe the usefulness of our approach combined with ICG-VAG and motor evoked potentials (MEP) for the intraoperative assess
