Identification of hepatic segment

Abstract

Near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG) is a novel imaging system. This technique is clinically used in sentinel node navigation of breast or foregut cancer, neurovascular or cardiovascular surgery, and liver surgery. In the field of liver surgery, intraoperative segmentation is one of the most beneficial NIRF imaging. In this chapter, counter and direct perfusion methods using NIRF imaging are proposed in order to perform intraoperative hepatic segmentation. With these techniques, we could clearly and continuously depict hepatic segment not only on the surface of the liver but also on the intraparenchymal segmental plane.
