Thoracoscopic Lobectomy for Right Upper Bronchial Atresia Combined With an Azygos Lobe of the Right Lower Lobe in an Infant Patient: A Case Report of a Rare Condition.

Bronchial atresia (BA) and azygos lobe (AL) are rare congenital pulmonary abnormalities in pediatric patients. We herein report an infantile case of BA combined with AL that was treated with thoracoscopic surgery. The patient was an 8-month-old boy who was preoperatively diagnosed with BA of the right upper lobe (RUL) combined with an AL using fetal magnetic resonance imaging and postnatal enhanced computed tomography. Thoracoscopic surgery using indocyanine green (ICG)-guided near-infrared fluorescence (NIRF) was performed for BA of the RUL. In the operative findings, the upper lobe bronchus was not recognized, and the pulmonary vessels of the RUL were confirmed using ICG-guided NIRF. The AL was connected to the right lower lobe (RLL). Partial RLL, including AL resection, was performed after RUL resection to prevent postoperative infections and torsion. The postoperative course was uneventful. Thoracoscopic surgery using ICG-guided NIRF was safely performed in an infant with a rare condition.
