Lung volume reduction surgery.
Background. Surgery to reduce lung volume has recently been reintroduced to alleviate dyspnea and improve exercise tolerance in selected patients with emphysema. A reliable means of identifying patients who are likely to benefit from this surgery is needed. Methods. We measured lung resistance during inspiration, static recoil pressure at total lung capacity, static lung compliance, expiratory ...
متن کاملHeterogeneity of lung volume reduction surgery outcomes in patients selected by use of evidence-based criteria.
BACKGROUND Despite its benefit, lung volume reduction surgery (LVRS) is underused, partially because of the heterogeneous responses and lack of recent outcomes data. METHODS Data from 59 consecutive emphysema patients who underwent LVRS were analyzed. The proportion of patients responding based on 6-minute walk distance (6-MWD), exercise capacity (watts), and forced expiratory volume in 1 sec...
متن کاملExercise performance and gas exchange after bilateral video-assisted thoracoscopic lung volume reduction for severe emphysema.
Lung volume reduction surgery (LVRS) improves dyspnoea and pulmonary function in selected patients with severe emphysema. The purpose of this study was to assess the effects of LVRS on exercise performance and gas exchange in relation to changes in pulmonary function. In 40 patients (63.2+/-1.4 yrs, mean+/-SE) with severe emphysema (forced expiratory volume in one second (FEV1) 29+/-1% predicte...
متن کاملValue of computed tomography for selecting patients with bullous lung disease for surgery.
Computed tomography and lung function tests were performed on 43 patients who had evidence on the chest radiograph suggesting bullous emphysema. After computed tomography scan two groups of patients could be identified. Twenty patients had generalised emphysema, which was locally worse in the area of the suspected bulla; and 23 had well defined bullae, which were potentially operable. Results o...
متن کاملImprovements in thoracic movement following lung volume reduction surgery in patients with severe emphysema.
In twelve patients with severe emphysema who underwent lung volume reduction surgery (LVRS), we assessed the results of dyspnea scale, pulmonary function, 6-minute walk distance (6MD), and thoracic movement prior to and 6 months following LVRS. Postoperatively, forced expiratory volume (FEV1), maximum inspiratory mouth pressures (MIP), maximum expiratory mouth pressures (MEP), maximum voluntary...
