[A case report: partial anomalous pulmonary venous return of the left lung communicating with the left atrium through the aberrant vein].

A rare case with partial anomalous pulmonary venous return was presented. The left superior pulmonary vein was drained into the left innominate vein via a common vertical vein and it also communicated with the left atrium via a small aberrant vein. All the other pulmonary veins were normally drained into the left atrium. The surgical repair was performed through the midline sternotomy. The junction of the vertical vein and the left innominate vein was ligated with slight elevation of the pressure in the left pulmonary vein. Under the cardiopulmonary bypass, the secundum atrial septal defect was closed by direct sutures. The postoperative course was uneventful and there was no pulmonary congestion in the left upper lung field.
