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.
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 ...
Some people may benefit from long-term oxygen therapy, lung volume reduction and lung transplantation. [22] In those who have periods of acute worsening, increased use of medications, antibiotics, corticosteroids and hospitalization may be needed. [23] As of 2015, COPD affected about 174.5 million people (2.4% of the global population). [7]
Bullectomy is a surgical procedure in which dilated air-spaces or bullae in lung parenchyma are removed. [1] Common causes of dilated air-spaces include chronic obstructive pulmonary disease and emphysema. Patients with giant bullae filling half the thoracic volume and compressing relatively normal adjacent parenchyma are recommended for ...
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]
