Postpneumonectomy pulmonary edema (PPE/PPO) is a subtype of non-cardiogenic pulmonary edema. As the name suggests it occurs after a pneumonectomy. It carries a high mortality rate.
Epidemiology
Associations
Postpneumonectomy pulmonary edema is thought to be associated more with
- right sided pneumonectomy 2
- repeat thoracotomy 2
- more positive fluid balance 2
- high intraoperative and postoperative urine outputs 3
Pathology
This occurs when the remaining lung shows increased extravascular fluid in the lung and pleura, resulting in respiratory distress and impaired gas exchange.
