Recruiting NA Emphysema

Compares treatment options for Emphysema

Official title Surgical Compared to Bronchoscopic Lung Volume Reduction in Patients With Severe Emphysema

ClinicalTrials.gov ID: NCT04537182

What this study is testing

What it's testing
The investigators plan to perform a randomized controlled trial that compares bilateral lung volume reduction surgery (LVRS) with bronchoscopic lung volume reduction (BLVR) using endobronchial valves in terms of efficacy and patient safety.
