Near-Infrared Fluorescence Identification of Thoracic Duct: Feasible and Safe in Various Patient Populations

The study evaluated the efficacy and safety of near-infrared fluorescence identification of the thoracic duct during left lateral neck dissection. Results showed that near-infrared fluorescence visualization successfully identified the thoracic duct in a higher percentage of patients compared to ambient light. The procedure was feasible and safe, even in patients with prior neck surgery or radiation. The optimal timing of indocyanine green administration was found to be within 3 minutes of injection. No chylous fistulas were observed postoperatively. These findings highlight the potential of near-infrared fluorescence as a reliable intraoperative imaging modality.
