ALONSO ALVARO, S et al. Nuevos procedimientos broncoscópicos en Argentina: Reducción volumétrica pulmonar endoscópica con válvulas endobronquiales. Rev. am. med. respir. [online]. 2016, vol.16, n.3, pp.258-268. ISSN 1852-236X.

Chronic Obstructive Pulmonary Disease (COPD) is characterized by airflow limitation, air trapping and dynamic hyperinflation that lead to disabling dyspnea despite appropriate pharmacologic treatment and pulmonary rehabilitation. Though surgical treatments such as lung transplant surgery and lung volume reduction (LVRS) are available, their high morbidity and mortality limit their use. To avoid these complications multiple procedures for bronchoscopic lung volume reduction have been developed, among which endobronchial valves (EBV) have accumulated the largest amount of evidence. While studies with EBV are heterogeneous and show modest benefits in pulmonary function tests, exercise capacity and quality of life, there is a group of patients with heterogeneous emphysema, intact interlobar fissure, severe air trapping and low exercise tolerance that show a statistically and clinically significant benefits. New studies are under way to further support the growing evidence.

Keywords : Emphysema; COPD; Endobronchial valves; Lung volume reduction surgery; Interventional bronchoscopy.
