Preoperative initiation of peripheral veno-arterial extracorporeal membrane oxygenation for a complex case of cardiac tamponade.

In this case report, we present an alternative approach to the anaesthetic management of patients presenting with delayed postoperative cardiac tamponade physiology. Given that pericardiocentesis was deemed unsafe, and a protracted surgical dissection was anticipated, peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support was established prior to induction of anaesthesia to prevent catastrophic circulatory failure. To the best of our knowledge, this is the first reported case of planned preoperative commencement of peripheral VA-ECMO in a complex case of cardiac tamponade. We discuss the challenges associated with this case and the process for selecting this strategy. We also describe the role of transoesophageal echocardiography in planning the surgical approach. This report is completed by a discussion on the topic of delayed postoperative pericardial effusion and tamponade.
