Post lung volume reduction pulmonary edema
It has been reported to occur in ~ 5% of right pneumonectomies, ~4% of left pneumonectomies, and 1% of all lobectomies 2.
It tends to precipitate in the early post-operative period. Two pathophysiological factors have been proposed 1.
- an increase in pulmonary capillary pressure associated with passage of a normal to high cardiac output in a reduced volume pulmonary vascular bed.
- injury to the alveolar capillary membrane
