A rare case of superior vena cava syndrome in a patient on VV-ECMO.

ABSTRACT

Superior vena cava (SVC) syndrome is caused by either extrinsic compression of SVC or intrinsic lesions within SVC leading to obstruction of SVC and consequently swelling of the face, neck, and upper extremeities. Iatrogenic incidence is on the rise due to the use of long-term indwelling catheters. SVC syndrome in extracorporeal membrane oxygenation (ECMO) has been defined in neonatal and paediatric ECMO cases. Only one case of SVC syndrome in adult has been defined while using a double-lumen ECMO cannula. Our case describes a case of SVC syndrome in a case on veno-venous ECMO (VV-ECMO) with an internal jugular vein (IJV) return cannula which is unheard of. A high index of suspicion is required to diagnose SVC syndrome.
