An unusual case of uninterrupted inferior vena cava with accessory hemizygous channel: An incidental finding in a child

Abstract

Azygos or hemizygous continuation of inferior vena cava (IVC) is diagnosed in the presence of intrahepatic interruption of IVC. We report a case of a 4-year-old, male child presenting with a history of poor weight gain. A detailed evaluation of the child revealed a diagnosis of hemizygous continuation of uninterrupted, but severely obstructed, IVC. This incidental finding has rarely been reported in the literature.

Intra-abdominal haemorrhaging after cardiac catheterisation: the importance of recognising vascular anomalies in heterotaxy syndrome

“…Cases of atrial inflow with narrowing of the inferior vena cava, similar to the present case, have also been reported. 4,5 Being aware of this type of inferior vena cava anomaly is important in preliminary echocardiography to avoid complications with cardiac catheterisation.…”
