Endobronchial valves for treatment of bronchopleural fistula in granulomatous polyangitis: a longitudinal case report.

Bronchopleural fistula (BPF) is an abnormal communication between the bronchus and the pleural space, commonly occurring after pulmonary resection or due to a spontaneous pneumothorax secondary to an underlying lung disease. We present a case of BPF in the setting of granulomatous polyangitis treated with endobronchial valves (EBV) with a longitudinal follow-up. These 1-way valves allow air and mucus to exit the diseased segment of lung during expiration, but prevent the reentry of air upon inspiration.
