Anomalous Pulmonary Venous Return Accompanied by Normal Superior Pulmonary Veins in the Left Upper Lobe: A Case Report

Abstract

Partial anomalous pulmonary venous return is a rare congenital pulmonary venous anomaly, in which some of the pulmonary veins drain into the systemic circulation rather than the left atrium. Many variants of partial anomalous pulmonary venous return have been reported. We present a rare type of partial anomalous pulmonary venous return in which the anomalous left upper lobe pulmonary vein drained into the left innominate vein via the vertical vein, accompanying the left upper lobe pulmonary vein in the normal location.
