Consolidating Lung Volume Reduction Surgery After Endoscopic Lung Volume Reduction Failure

BackgroundBronchoscopic valve placement constitutes an effective endoscopic lung volume reduction (ELVR) therapy in patients with severe emphysema and low collateral ventilation. After the most destroyed lobe is occluded valves, significant target leads to improvements function, exercise capacity, quality of life. The effects are not consistent some patients, leading long-term failure. We hypothesized that surgical (LVRS) would reestablish ELVR short-term clinical after failure.MethodsThis retrospective single-center analysis included all who underwent consolidating LVRS by lobectomy failure between 2010 2015. Changes forced expiratory 1 second, residual volume, 6-minute walking distance, Modified Medical Research Council dyspnea score 90 days were analyzed, outcomes both procedures compared.ResultsLVRS was performed 20 A lower 90%. 30-day mortality cohort 0% 90-day 5% (1 20). remaining 19 showed a increase second (+27.5% ± 19.4%) (−21.0% 17.4%) total capacity (−11.1% 11.1%). This resulted tolerance (6-minute distance: +56 60 m) relief (ΔModified Council: −1.8 1.4 points.).ConclusionsConsolidating previously successful feasible results symptom improvement function.
