Abstract:
Currently there is no explicit guideline for the use of indocyanine green (ICG) in the localization of pulmonary nodules before surgery. How long ICG can remain in vivo is unknown. According to previous reports, ICG can be observed under infrared thoracoscope within 24 hours after injection. We unexpectedly found a case of a 54-year-old man who was injected with ICG under CT guidance, which was still clearly visible under infrared thoracoscopy after 6 days. This unexpected finding suggests that the operation time can be arranged appropriately after local injection with ICG.
