The use of ICG enhanced fluorescence for the evaluation of parathyroid gland preservation

Abstract

Indocyanine green (ICG) enhanced fluorescence imaging is recent innovation as the "realtime intraoperative imaging" technique. Many clinical studies have been reported in the literature which use different devices and techniques that employ various doses and usages of ICG as a non-specific contrast agent. Several groups have performed studies in endocrine surgery, especially with regards to parathyroidrelated outcomes after thyroid and parathyroid surgery. However, there is no consensus on the technical details that should be applied. With this study, we aimed to review the current literature on potential use of intraoperative ICG angiography for evaluating parathyroid gland (PTG) preservation.
