A In vitro binding experiments of indocyanine green (ICG) and human serum albumin (HSA) suggested that a 1:6 molar ratio and a configuration temperature of 37°C were optimal. B During surgery, after extrahepatic Glissonean isolation of the liver pedicle planned for resection, the ICG-HSA complex was administered through a peripheral vein using an infusion pump. C ICG-HSA metabolism comprises three stages: intravascular, liver, and systemic clearance. D The actual intraoperative fluorescence imaging and guidance effects of ICG-HSA in laparoscopic fluorescence negative-staining right hemihepatectomy.
