A Case of Venous Aneurysm of the Superior Vena Cava Following Systemic-to-Pulmonary Artery Shunt / 日本心臓血管外科学会雑誌

ABSTRACT

A 13-year-old girl with asplenia syndrome who previously had undergone left subclavian-to-pulmonary artery shunt after removal of a cavopulmonary shunt with interposition of a short segment of the left superior vena cava was admitted for congestive heart failure. Angiography revealed aneurysmal dilatation of the left superior vena cava. Percutaneous coil embolization of the shunt was successfully performed and the venous aneurysm was diminished. Interposition of a venous component in systemic-to-pulmonary artery shunt should be avoided even after removing a cavopulmonary shunt.
