Lung volume reduction (LVR) is a new surgical approach designed to relieve shortness of breath and to improve exercise tolerance in patients with severe lung emphysema. Selection of patients for LVR is based on history, clinical investigation, chest X-ray studies, CT scan, lung perfusion scan, lung function testing, and blood gas analysis. Selection criteria are severe emphysema (FEV1 20-35% pred., TLC > 120% pred., RV > 250% pred.), dyspnea despite optimized medical therapy, abstinence from smoking, acceptable nutritional status and rehabilitation potential. ⋯ Three cases of a delayed pneumothorax were observed. Early hospital mortality (< 30 days) was 1.7% and 90 days mortality 3.4%. Few follow-up data are available beyond 1 year, and the long-term benefit of LVR surgery therefore remains to be defined.
