Misdiagnosis of aortic atresia due to catheter malposition.
A single film portable aortogram through a highly placed umbilical artery catheter suggested aortic atresia, but subsequent study revealed a normal aorta and a patent ductus arteriosus. This demonstrates the importance of proper catheter placement in single film portable aortography, which is a reliable diagnostic tool in the evaluation of distressed neonates.
