Official Title: Lung Volume Reduction in COPD Patients With an Inhomogeneous Severe Emphysema Located in the Upper Lobes, by Injecting Warm Saline Through the Bronchoscope Channel
Brief Summary:
Aim: To evaluate feasibility, safety and efficacy of relatively simple approach of bronchoscopic lung volume reduction (LVR) technology, independent of collateral ventilation.
Description: Patients with severe upper lobes heterogeneous emphysema, undergo unilateral bronchoscopic installation of saline thermal energy 50-55 ºC intending to induce an inflammatory airway and parenchymal injury and consequently fibrotic response resulting in LVR;
