Non-constructive Supracardiac Total Anomalous Pulmonary Venous Connection With Giant Superior Vena Cava Aneurysm

Giant superior vena cava (SVC) aneurysm in obstructive supracardiac total anomalous venous connection (TAPVC) is rare, and there has not been a giant SVC aneurysm reported in non-obstructive TAPVC. Here we reported a 29‐year‐old female with non-obstructive TAPVC and a giant SVC aneurysm. Routine TAPVC correction and partial venoctomy were done, considering that such a giant aneurysm in a non-obstructive venous arch might have its histological etiology and higher risk of thrombosis and/or rupture.
