A Case of Persistent Air Leak Managed by Selective Left Main Bronchus Intubation in an Infant with Pulmonary Tuberculosis.

BACKGROUND Persistent air leak, or persistent pneumothorax, is defined as a pneumothorax that persists beyond the first week, or air leak through a chest drain for more than 48 hours. The most common findings in pediatric pulmonary tuberculosis are parenchymal disease and mediastinal lymphadenopathy, but airway obstruction can cause emphysema and pneumothorax. A case is presented of persistent air leak in a 3-month-old infant with pulmonary tuberculosis that was managed by selective left main bronchus intubation.
