Abstract
We herein report a case of an 18-year-old male with left postpneumonectomy syndrome who underwent a bullectomy for right pneumothorax. The patient underwent a left pneumonectomy at the age of 1 year. At the age of 18 years, he developed right pneumothorax, and radiological findings revealed apical bullae in the right pleural cavity extending into the left atrophic thoracic cavity beyond the upper mediastinum. The right thoracoscopic bullectomy was successful. Modifications of selective lobar ventilation during surgery and thoracoscope position were described.
