Surgical Correction of Left Superior Vena Cava Draining to Left Atrium Associated with Superior Vena Cava Syndrome

抄録

A case is reported of anomalous drainage of a persistent left superior vena cava to the left atrium associated with stenotic right superior vena cava. The anomaly was reflected by mild cyanosis and superior vena cava syndrome. Surgical relief was accomplished by transposing the left superior vena cava to the right appendage and widening the right superior vena cava with a pericardial patch graft.
