Bronchoscopic Lung Volume Reduction

Since the publication of the National Emphysema Treatment Trial study, lung volume reduction (LVR) has been considered a therapeutic alternative for patients with advanced obstructive lung disease. The high complication rate of surgical LVR has led to the development of bronchoscopic LVR (BLVR). Of the currently available BLVR alternatives, coils and unidirectional endobronchial valves lead the list. The choice of each device depends on emphysema characteristics and the presence of collateral ventilation. Evaluation of these patients at centers with expertise in interventional pulmonology and management of BLVR is strongly recommended.
