Bronchoscopic lung volume reduction

Bronchoscopic lung volume reduction (BLVR) is a procedure to reduce the volume of air within the lungs. BLVR was initially developed in the early 2000s as a minimally invasive treatment for severe COPD that is primarily caused by emphysema. BLVR evolved from earlier surgical approaches first developed in the 1950s to reduce lung volume by removing damaged portions of the lungs via pneumonectomy or wedge resection. Procedures include the use of valves, coils, or thermal vapour ablation.
