Bilateral lung volume reduction surgery.

A new surgical approach, bilateral lung volume reduction surgery (LVRS), offers hope for select patients with chronic pulmonary emphysema (CPE). Bilateral LVRS procedures involve excision of emphysematous alveoli, which results in a 20% to 30% reduction in the volume of each lung. The goal of LVRS is to improve the respiratory mechanics of patients with CPE by reexpanding functional lung tissue compressed by overdistended emphysematous alveoli, restoring diaphragmatic mobility, and improving the bellows function of the chest wall structures. Patients undergoing bilateral LVRS procedures experience relief from chronic dyspnea and may note improved pulmonary functions and better quality of life.
