Percutaneous endovascular treatment of an iatrogenic superior cava vein syndrome during the immediate post-operative period after mitral-aortic valve replacement. / Tratamiento endovascular percutáneo de un síndrome de vena cava superior en el postoperatorio inmediato de recambio valvular mitroaórtico.

Superior vena cava syndrome (SVCS) results from superior vena cava obstruction, causing a decrease in venous return from the head, neck, and upper extremities. Although the most frequent cause is still malignant tumour processes, in recent years an increase has been observed in non-tumour causes, such as thrombosis of intravascular devices or iatrogenic causes during cardiac surgery. A case is presented of SVCS after cardiac surgery treated satisfactorily by an endovascular technique and systemic anticoagulation.

Double intracardiac thrombosis in a patient assisted by a venoarterial extracorporeal membrane oxygenation. / Trombosis intracardíaca doble en paciente asistido mediante membrana de oxigenación extracorpórea venoarterial.

Intracardiac thrombosis is a rare complication in patients receiving haemodynamic support with venous-arterial extracorporeal membrane oxygenation (VA-ECMO), but it has a high risk of mortality. This case report describes a patient who suffered cardiogenic shock after a ST-segment elevation myocardial infarction (STEMI) and who presented with intracardiac thrombosis during VA-ECMO support on two occasions after mitral valve replacement. The first one was after the insertion of a mechanical prosthesis, and the second, after replacing it with a biological valve.
