Drainage of the Inferior Vena Cava Into the Left Atrium with Atrial Septal Defect and Partial Anomalous Pulmonary Venous Return: Initial and Postoperative Computed Tomography (CT) Findings

Abstract

Anomalous drainage of the inferior vena cava into the left atrium is a rare congenital vascular disorder. It can occur with atrial septal defect, anomalous pulmonary venous drainage, and pulmonary arteriovenous fistula. Hereby we describe the computed tomography (CT) findings of a rare combination of drainage of the inferior vena cava associated with atrial septal defect and partial anomalous pulmonary venous return.
