Lung volume reduction surgery

Lung volume reduction surgery, or LVRS, can improve the quality of life for certain COPD and emphysema patients. Parts of the lung that are particularly damaged by emphysema are removed, allowing the remaining, relatively good lung to expand and work better.

Conventional LVRS involves resection of the most severely affected areas of emphysematous, non-bullous lung (aim is for 20-30%). This is a surgical option involving a mini-thoracotomy for patients suffering end stage COPD due to underlying emphysema, and can improve lung elastic recoil as well as diaphragmatic function.

Increased mortality, contraindicating the procedure, is noted in patients that have both:

The National Emphysema Treatment Trial (Fishman et al., 2003) was a large multicentre study (N = 1218) comparing LVRS with medical treatment. Results suggested that:
