Bifurcating Patent Ductus Arteriosus: A Rare Anomaly Associated with a Congenital Portosystemic Shunt
摘要
Malformation of the ductus arteriosus (DA) is uncommon in otherwise healthy newborns. We report an extremely rare aneurysmal DA with bifurcation, in which the superior branch connects at the typical location on the roof of the main pulmonary artery, while the inferior branch connects to the left aspect of the left pulmonary artery origin. This unusual DA configuration is associated with an intrahepatic congenital portosystemic shunt.
