I had a pt s/p RUL thoracotomy for lung CA who had two chest tubes to water seal. I assume one was for the pleural space and one was in the mediastinum? She had serosanguinous drainage into the CT. Her most recent Xray showed a small pneumothorax on that side.
My question is, how can a pneumothorax remain if she's been with a CT since her surgery? I understand the fluid would still come out but air? Thanks.
