Abstract
An anomaly of pulmonary venous drainage in an 8-year-old child is described whereby all four pulmonary veins emptied into a common chamber which in turn communicated with both the left atrium and the inferior vena cava. The venous anomaly and an accompanying atrial septal defect were demonstrated by selective cineangiocardiography. Ligation of the vein at the level of the right diaphragm, thus rerouting the entire pulmonary venous return through the alternate pathway to the left atrium, was tolerated without difficulty. The embryology, diagnosis, and surgical management of the anomaly are discussed.
