Secondary pneumothorax represents a challenging problem in patients with chronic obstructive
pulmonary disease, due to their compromised health status. In this case, an endobronchial
one-way valve was inserted in the left lower lobe by flexible bronchoscopy, resulting
in a complete resolution of air leak and lung reexpansion. Endobronchial valve could
represent a new option for the management of persistent air leak in patients not suitable
for surgical procedures.
