Bronchial fenestration improves expiratory flow in emphysematous human lungs.


BACKGROUND The crippling effects of emphysema are due in part to dynamic hyperinflation, resulting in altered respiratory mechanics, an increased work of breathing, and a pervasive sense of dyspnea. Because of the extensive collateral ventilation present in emphysematous lungs, we hypothesize that placement of stents between pulmonary parenchyma and large… (More)
