Cardiac Arrest Caused by an Acute Intrathoracic Gastric Volvulus Treated With Percutaneous Gastrostomy.

During cardiopulmonary resuscitation, one of the first priorities after establishing basic and advanced life support is to identify the cause of the arrest. We present a rare case of cardiac arrest due to a decreased venous return from mediastinal shift caused by a paraesophageal hernia with an incarcerated thoracic gastric volvulus, which was treated by percutaneous gastrostomy.
