[A successful surgical case of bilateral partial anomalous pulmonary venous connection without atrial septal defect]

Abstract

We performed the new operative method for bilateral partial anomalous pulmonary connections (PAPVC) without atrial septal defect (ASD). A 11-years-old boy was admitted for operation. The right upper pulmonary vein returned to the superior vena cave (SVC), and left upper pulmonary vein returned to the innominate vein. Atrial septum was intact. The Qp/Qs was 1.94. The right atrium (RA) was opened and ASD was created. Continuity between the distal end of the SVC and RA was re-established by end-to-end anastomosis to the right atrial appendage. The proximal end of the SVC was closed. The right anomalous pulmonary vein remained in situ on the lower segment of SVC, blood being directed to the left atrium (LA) through the created ASD by suturing the posterior flap of RA incision to the atrial septum well away from the sinoatrial node and artery, anomalous pulmonary vein and cavoatrial junction. The anomalous left vertical vein was dissected up to the innominate vein. The left pulmonary vein was mobilized as much as possible, and was anastomosed to the posterior wall of LA by end-to-side fashion. He has normal sinus rhythm and no evidence of pulmonary venous obstructions on both sides. We support the efficacy of this method as an alternative in the management of this disorder.
