Endoscopic volume reduction before or after lung transplantation

Endobronchial valve therapy in patients with severe emphysema achieves similar clinical benefits to lung volume reduction surgery without the potential morbidity. We report successful endobronchial valve treatments in two patients with severe emphysema. Valves were placed in the first patient 5 months before lung transplantation and in the second patient 10 years after lung transplantation, using a flexible bronchoscope under local anaesthesia. The objective was to reduce pulmonary hyperinflation and improve lung function. The potential benefit of this procedure was anticipated by lobar collateral ventilation measurements. Two months later, forced expiratory volume in 1 s, forced vital capacity and dyspneoa improved in both cases.
