Systemic venous collateral channel causing desaturation after bidirectional cavopulmonary anastomosis: percutaneous closure.
An infant with cyanotic cardiac disease that was palliated with a bidirectional cavopulmonary shunt developed progressive and worsening cyanosis 5 years after the surgical procedure. A large venous collateral was found to be decompressing the bidirectional Glenn shunt from the superior caval vein to the inferior caval vein and was percutaneously closed with a vascular plug. The unusually large venous collateral, and the excellent outcome associated with percutaneous procedure are discussed.
