Bronchoscopic Lung Volume Reduction in Management of Localized Emphysema

Emphysema is a progressive phenotype of chronic Obstructive Pulmonary Disease (COPD), poses a significant global health burden characterized by irreversible lung parenchymal destruction and airspace enlargement. In recent years, bronchoscopic lung volume reduction (BLVR) has considerable interest as a minimally invasive approach to reducing hyperinflation and improving lung function in patients with emphysema. BLVR techniques aim to achieve lung volume reduction by occluding or ablating emphysematous lung tissue through endobronchial delivery of various agents. Many techniques are available for BLVR as coil, endo-bronchial valve, and biological as thrombin, autologous blood and chemicals as silver nitrate solution.
