Surgical treatment of partial anomalous pulmonary venous connection of the left lung (It-PAPVC).

Between January 1981 and December 1983, 4 patients, aged 6 to 50 years, with It-PAPVC were operated upon at the Kokura Memorial Hospital, by a new technique of anastomosis between the left anomalous PV and the left auricular appendage. One patient, a 9-year-old male, had unilateral anomalous pulmonary venous connection of the entire left lung to the innominate vein. The other three patients had partial anomalous pulmonary venous connection from the left upper lobe to the innominate vein. Two patients has pulmonary valvular stenosis, and the other two had ASD. All patients were operated upon through a midsternal incision. After cardiopulmonary bypass was established, the anomalous vein was divided as high as was reachable. The present operative method involved the use of an oval pericardial gusset extending from the left auricular appendage into the split anomalous vein so as to obtain a wide anastomotic orifice. Other associated congenital anomalies were simultaneously corrected. All patients had uneventful recovery and at postoperative cardiac catheterization and angiography, the anastomosis between the pulmonary vein and the left auricular appendage was widely patent.
