[Lung volume reduction surgery (LVRS): criteria for selecting patient in Antonio Pedro Hospital, Federal Fluminense University, Niter i city, Rio de Janeiro, Brazil].
BACKGROUND
Chronic Obstructive Pulmonary Disease (CPOD) is an important problem in Brazil and other countries. The clinical treatment of ambulatory patients is now reasonably standardized. Lung volume reduction surgery (LVRS) is an alternative of surgical treatment of emphysema (aside from lung transplantation).


OBJECTIVE
The aim of this study was to analyse patient selection criteria for LVRS.


METHODS
This study was carried out using a sample of 31 patients referred to and given assistance to at the Smoking and Chronic Obstructive Pulmonary Disease Outpatient Ward Antonio Pedro Hospital, who were evaluated to check whether or not they could be eligible for LVRS. Aiming at evaluating the major criteria for eligibility for LVRS, the patients underwent a protocol including standardized anamnesis and physical examination, spirometry with maximum inspiratory and expiratory flow volume curves associated with post-bronchodilatator test, room air arterial blood gases, a six-minute walking test, plain chest roentgenograms and left lateral chest roentgenograms, high-resolution chest computed tomographic scans and lung perfusion scans. Statistical analysis was conducted with description of data proportions.


RESULTS
Contraindications to surgery included chronic bronchitis (29% or nine patients), forced expiratory volume in one second (FEV 1) more than 80 percent predicted (13% or four patients), negative consent for surgery (10% or three patients), fibrosis pattern, severe depression and bronchiectasis (two patients each one), solitary pulmonary nodule, severe obesity, severe bullous emphysema, pulmonary hipertension, pulmonary resection history, current cigarette smoking, diffuse emphysema with alpha-1-antitrypsin deficiency and severe cardiac disease (one patient each). Indication. One selected patient with severe symptoms of emphysema met criteria for LVRS (bilateral superior lobe heterogeneous pattern of emphysema on chest computed tomography and lung perfusion scan).


CONCLUSIONS
Chronic bronchitis was the major isolated factor to contraindicate LVRS. Most patients who fit the criteria for the surgery performance refused to undergo the LVRS for fear of the surgery and after pulmonary rehabilitation. The most important criteria for LVRS is bilateral superior lobe heterogeneous pattern of emphysema.
