Case report of cardiac herniation after sleeve pneumonectomy with superior vena cava reconstruction.

Cardiac herniation is a complication that occurs after intrapericardial pneumonectomy. It is life-threatening unless promptly diagnosed and surgery performed. We report a case of cardiac herniation after right intrapericardial pneumonectomy following radiotherapy for lung cancer. The patient developed cardiac herniation with sudden hypotension following a switch to the spine position. An immediate switch to the lateral decubitus position improved the cardiocirculatory dynamics, and surgical patch closure was performed. The circulation dynamics was unstable for several hours after surgery with elevated enzyme levels, which improved 2 days later. Immediate thoracotomy before irreversible myocardial damage resulted in a successful outcome. The risk of cardiac herniation should always be considered after intrapericardial pneumonectomy.
