Post pneumonectomy pulmonary oedema

[Karim Brohi]

Recently had a fit adult admitted following penetrating injury to the right
chest with injury of the lower lobe of the lung extending to the hilum with
associated extra-pericardial pulmonary vein laceration.  Had a right
pneumonectomy as very coagulopathic with oversew of the pulmonary vein. 

Initially did well, extubated at 24 hours, comfortable, haemoserous drainage
from chest tubes. 12 hours later after a couple of transient dips in
saturation developed acute pulmonary oedema, froth coming up the ET tube,
and died within minutes.  

Any ideas?
