Successful Treatment of a Giant Emphysematous Bulla with an Endobronchial Valve in a Patient with Contralateral Lung Cancer.

Patients with severe emphysema have a higher risk of developing lung cancer, and their surgical risk increases when emphysema is accompanied by a giant bulla. Here, we describe a patient who had an emphysematous giant bulla in the right upper lobe that was treated with an endobronchial valve placement. Subsequently, a cancerous lesion on the contralateral lung was successfully removed by lobectomy.
