Communication between the two pleural cavities after major cardiothoracic surgery: relevance to percutaneous intervention.

The authors describe evidence of communication between the two pleural cavities after major cardiothoracic surgery (combined heart and lung transplantation, heart transplantation, and correction of complex congenital heart disease) performed in three patients. In two patients, unilateral lung biopsy caused a symptomatic bilateral pneumothorax. This was successfully treated with insertion of a single chest tube in one patient and two chest tubes in the other patient. In the third patient, simultaneous evacuation of large bilateral pleural effusions was performed by means of unilateral thoracentesis because of the presence of a common pleural cavity.
