Background: When indocyanine green (ICG) is administered before surgery, it accumulates in lung metastases of hepatocellular carcinoma (HCC), causing the tumor to fluoresce. Additionally, during pulmonary segmentectomy, the intersegmental plane can be made fluorescent by administering ICG intraoperatively. We here report segmentectomy for pulmonary metastasis of HCC using "dual ICG fluorescence imaging", in which we combined tumor fluorescence by preoperative ICG administration and intersegmental plane fluorescence by intraoperative ICG administration.
