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 [ 1 ] [ 2 ] as a minimally invasive treatment for severe COPD that is primarily caused by emphysema .
Lung volume reduction surgery, or LVRS, can improve the quality of life for certain patients with COPD of emphysematous type, when other treatment options are not enough. Parts of the lung that are particularly damaged by emphysema are removed, allowing the remaining, relatively good lung to expand and work more efficiently.
Where there is severe emphysema with significant hyperinflation that has proved unresponsive to other therapies, lung volume reduction surgery (LVRS) may be an option. [51] [52] LVRS involves the removal of tissue from the lobe most damaged by emphysema, which allows the other lobes to expand and give improved function. The procedure appears to ...
This can be performed for persistent post-operative air leaks and also for bronchoscopic lung volume reduction (BLVR), a less invasive alternative to lung volume reduction surgery (LVRS) Bronchial thermoplasty for asthma; Whole lung lavage, the standard treatment for pulmonary alveolar proteinosis; Tunneled pleural catheter placement.
For severe emphysema that has proved unresponsive to other therapies lung volume reduction surgery (LVRS) may be an option. [201] [202] LVRS involves the removal of damaged tissue, which improves lung function by allowing the rest of the lungs to expand.
Pulmonary rehabilitation programmes involve intensive exercise training combined with education and are effective in improving shortness of breath. Severe emphysema has been treated with lung volume reduction surgery, with in carefully chosen cases. Lung transplantation is also performed for severe COPD in carefully chosen cases. [10]
Although endobronchial isolation techniques for emphysema were developed in the early 2000s, [6] specific valves were developed primarily by the start-up medical device company Emphasys Medical (now Pulmonx - Redwood City, California) as a minimally invasive alternative to lung volume reduction surgery for emphysema. In lung volume reduction ...
The presence of interlobar collateral ventilation will affect the choice of lung volume reduction procedure that may be offered in severe cases of emphysema. Emphysema usually develops in later years from the breakdown of alveolar walls resulting in much larger airspaces and much larger pathways for a preferential route of collateral ventilation.
