A radical correction involving Vargas's method and a direct anastomosis between the left pulmonary vein (PV) and left atrium (LA) was performed in a 29 day-old infant with supracardiac type Ib total anomalous pulmonary venous return (TAPVR) and an unusual form of the left PV. the left upper and lower PVs drained into a left "common" PV that was just behind the LA, and then into the right pleural cavity. The left common PV was located cephalad to the normal course and received blood from the right lower and upper PVs and drained into the supra-vena cava (SVC). The junction of the SVC and the right PV was slightly stenotic. Vargas's method is a useful technique for Darling's classification Ib TAPVR even in cases without the common PV situated behind the LA. But this patient had a left common PV and it was possible either to anastomose the common PV and LA directly or to perform Vargas's technique. We performed both procedures to prevent left PV obstruction (PVO). Cineangiography performed 2 months after surgery showed that a large amount of blood from the right and left PV drained into the LA through the common PV-LA route. These procedures, which create a dual PV channel, reduce the risk of PVO, so they are useful for radical correction of Darling's Ib type TAPVR.
