Endobronchial valve for secondary pneumothorax in a severe emphysema patient.

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.
