Bronchoscopic Lung Volume Reduction in Management of Localized Emphysema
Recruiting now · Not applicable
Conditions studied: Bronchoscopic Lung Volume Reduction
In brief
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.

You may qualify if…
- COPD of grade III and IV according to GOLD 2024 staging of COPD with localized (heterogeneous) emphysema as determined by high resolution computerized tomography (HRCT) of the chest with area of destruction >-950 Hounsfield units (HU) and respiratory symptoms despite optimal medical therapy with the following criteria: Patient less than 75 years of age not candidate for or had refused lung volume reduction surgery but fit for fibro-optic bronchoscope (FOB).
