Transcatheter closure of Abernethy malformation associated with interrupted inferior caval vein and other systemic venous anomalies

Abstract

AbstractAbernethy malformation is a rare entity. We report a 5-year-old boy presenting with severe pulmonary hypertension in whom Abernethy malformation and inferior caval vein interruption were diagnosed by CT angiography. In addition, the iliac veins were thrombosed with multiple venous collateral drainage. This abnormal venous anatomy caused difficulty in device closure of the Abernethy malformation, which was successfully closed using a vascular plug.
