Is the reduction of forced expiratory lung volumes proportional to the lung parenchyma resection, 6 months after pneumonectomy?
To preoperatively estimate the degree of first-second forced expired volume (FEV1) and forced vital capacity (FVC) reduction 6 months after pneumonectomy, according to the preoperative performed spirometry and bronchoscopy, and to estimate if the expected postoperative values of FEV1 and FVC are in accordance with the actual values.
