Application of ICG@HSA Complexes in Fluorescence Image-Guided Laparoscopic Anatomical Liver Resection

After ligation of the target hepatic segmental portal vein, the novel ICG regimen (0.5 mg ICG powder and 500 mg human serum albumin added to 20 ml saline, shaken and allowed to stand for more than 5 minutes, ICG: 0.025 mg/ml, human serum albumin: 25 mg/ml) was intravenously infused continuously at a rate of 1 ml/min until significant fluorescence imaging appeared in the demarcated area, upon which the infusion was terminated.

After ligation of the target hepatic segmental portal vein, 2.5 mg of ICG (2.5 mg/ml) was intravenously injected.
