The pressure-volume (P-V) characteristics were investigated in 14 excised left human lungs and their individual lobes. Comparison of the upper and lower lobar P-V curves of the emphysema-free and emphysematous lungs showed no significant difference when plotted as per cent lobar volume at a transpulmonary pressure (PL) of 30 cm H2O (V30). However, when in the emphysematous lungs the more severe...

BACKGROUND Lung volume reduction surgery has been recommended for patients with upper lobe predominant emphysema and was associated with less favorable outcomes in patients with non-upper lobe predominant emphysema. The value of endobronchial valve (EBV) treatment in lower lobe predominant emphysema has not been studied. OBJECTIVES To confirm the equivalence of upper and lower lobe valve trea...

Objective: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. Methods: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted...

AIM Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." MATERIALS AND METHODS We ...

Congenital lung anomalies are increasingly diagnosed in adults, because they are missed in childhood, or as a consequence of incomplete resections at a younger age. They have unique manifestations, often mimic other thoracic pathology, and can present acutely and necessitate emergent evaluation and management. Misdiagnosis is common. This article deals with the patterns of presentation, clinica...
