Stenting of Ductus Arteriosus in a Neonate with Truncus Arteriosus and Interrupted Aortic Arch Associated with a Right Aortic Arch

This report describes a case in which successful stenting of ductus arteriosus (DA) was performed for a 27-day-old boy with truncus arteriosus (TA) and interrupted aortic arch (IAA). The patent DA was associated with a right aortic arch. During the balloon catheter crossing of the ductus, the DA and descending aorta shifted toward the left side, making appropriate stent placement difficult. Additionally, the DA was longer than in previously reported cases with left aortic arch, thus requiring a longer stent. This experience suggests that DA stenting in neonates with TA and IAA averts surgical repair during the early neonatal period.
