[A case of isolated anomalous return of bilateral superior pulmonary veins]

A 14-year-old girl was admitted for evaluation of heart murmur. Intravenous digital subtraction angiography (DSA) showed the right superior pulmonary vein drained into the superior vena cava and the left superior pulmonary vein drained into the innominate vein. At the operation, an anomalous bilateral superior pulmonary venous return with an intact atrial septum was confirmed. An atrial septal defect was created and the right superior pulmonary vein was baffled into the left atrium with a pericardial patch. The left superior pulmonary vein was divided and anastomosed to the left inferior pulmonary vein with a expanded polytetra-fluoro-ethylene graft. Post-operative DSA showed satisfactory long-term result of the operation.
