Intraoperative evaluation of regional portal uptake function

Abstract

This chapter covers a recent important topic relevant to fluorescence imaging techniques with administration of indocyanine green (ICG), which are reportedly useful and have been applied to liver resection and liver transplantation. Despite recent advances in preoperative imaging study enabling estimation of the regional liver volume, the functional decrease in the region without venous drainage remains unclear. We herein describe ICG-fluorescence imaging technique evaluating regional portal uptake in the liver during surgery and clinical application for liver resection and liver transplantation to improve the safety of hepatobiliary surgery.
