Background: Cardiac herniation is a fatal post pneumonectomy complication. We report the signs, clinical findings, diagnosis and management of a patient with post pneumonectomy cardiac herniation.

Case report: A 34-year-old man with lung cancer underwent left pneumonectomy with partial pericardiectomy in the right lateral decubitus position. At the end of the surgery, cardiovascular collapse, severe bradycardia, desaturation and elevated airway pressure occurred just after repositioning the patient to the supine position. This patient survived as we returned him to the right lateral decubitus position and avoided the use of positive pressure ventilation.

Conclusions: Attention to the acute complications of pneumonectomy, diagnosis and rapid therapeutic interventions is essential in post pneumonectomy care.
