Application of indocyanine green in thoracic surgery: A review article

Indocyanine green has been used in clinical practice for a long time because of its many advantages such as stable coloration, safety and cheapness. With the widespread development of thoracoscopic technology, thoracic surgeons have a higher demand for the identification of lesions and tissue structures under the thoracoscope, and the traditional white light imaging can no longer fully meet the needs of thoracic surgeons. In this situation, indocyanine green combined with NIR imaging technology has brought great help to thoracic surgeons. For example, indocyanine green plays an important role in the localization of small pulmonary nodules, the imaging of intersegmental lung planes, the imaging of thoracic ducts, and the assessment of blood supply to the tubular stomach. In this paper, we review the application of indocyanine green in thoracic surgery according to the related research and application at home and abroad.
