EP.07A.20 Intraoperative Near-infrared Fluorescence Visualization of the Pulmonary Bronchus with Indocyanine Green Inhalation

Back to course

Pdf Summary

The document discusses a novel approach to visualizing the pulmonary bronchus during thoracoscopic surgery using indocyanine green (ICG) inhalation combined with a near-infrared fluorescence (NIF) system. This method aims to reduce intraoperative tracheobronchial injuries, a rare but serious complication of lung surgery. The use of ICG inhalation provides a clear view of the bronchus, facilitating identification of finer segmental and subsegmental bronchi, which is increasingly important due to the growing number of segmentectomies being performed.<br /><br />The case presented involves a 58-year-old woman undergoing thoracoscopic segmentectomy to treat a ground glass opacity in the anterior segment of the right upper lobe. During the procedure, ICG was inhaled into the lung on the operative side after single-lung ventilation for five minutes. This approach allowed the bronchus to be clearly visualized in green under the NIF system, enabling the surgical team to accurately identify the bifurcation of the anterior and apical bronchi. The bronchus was fully dissected and safely cut off using an endoscopic stapler, with no adverse events recorded.<br /><br />The findings indicate that ICG inhalation is both feasible and safe, offering significant potential for enhancing surgical precision and reducing the risk of tracheobronchial injuries during lung surgeries. Consequently, this technique represents a promising advancement for thoracic surgeons, providing a straightforward and effective method for bronchus visualization during surgery.
