Total Anomalous Pulmonary Venous Return with the Circular Pulmonary Venous Connection: Outcome of Common Pulmonary Venous Agenesis

摘要

A rare case of total anomalous pulmonary venous return, in which the right and left peripheral pulmonary veins connected circularly and there was no central part of the pulmonary vein or the common pulmonary vein, is presented. To our knowledge, total anomalous pulmonary venous return with circular pulmonary venous connection has not been reported previously in the literature. It is thought that the complex connection between peripheral pulmonary veins with the absence of the central part of the pulmonary vein as well as the common pulmonary vein results from common pulmonary venous agenesis.
