Successful palliation of acute superior vena caval obstruction after the Senning operation.

Superior vena caval obstruction after an intraatrial baffle procedure can lead to acute cerebral complications and hence requires immediate management. We present a case of successful palliation of acute superior vena caval obstruction after a Senning procedure by establishing a venous shunt between the innominate vein and pulmonary artery. This technique resulted in immediate hemodynamic and functional improvement that subsequently allowed for the enlargement of the superior vena cava-right atrial junction with a pericardial patch.
