Intraoperative real-time hemodynamics in intralobar pulmonary sequestration using indocyanine green and near-infrared thoracoscopy

A 33-year-old man with left pulmonary sequestration was admitted to our hospital. We planned left basilar segmentectomy to preserve the lung function, using indocyanine green (ICG) and near-infrared thoracoscopy. The intravenous (IV) administration of ICG (0.1 mg/kg) showed the distribution of fluorescence from the aberrant arteries, blood flow blockage from the aberrant arteries after they were divided, and the superior-basal boundary after the pulmonary artery and vein were divided. In adult patients with intralobar pulmonary sequestration, ICG and near-infrared thoracoscopic techniques are useful to confirm abnormal hemodynamics and demonstrate a safe and successful basilar segmentectomy.
