Abstract

Intravenous indocyanine green (ICG) has been reported to localize intra-abdominal metastatic lesions in several clinical trials. Our pilot study aimed to investigate the feasibility and safety of ICG fluorescence localization in pulmonary metastasectomy using a near-infrared fluorescence thoracoscope. Each patient received intravenous 0.25 or 0.5 mg/kg of ICG. The maximum diameter of the tumor on computed tomography ranged from 0.5 to 3.5 (median: 1.15) cm. Intravenous ICG injection localized pulmonary metastases in a portion (3 patients) of the enrolled patients. Our preliminary results provided us with important information to modify the study protocol.
