Efficacy of Prostaglandin E1 in Relieving Obstruction in Coarctation of a Persistent Fifth Aortic Arch Without Opening the Ductus Arteriosus

摘要

A persistent fifth aortic arch (PFAA) with coarctation and type A interruption of the fourth arch was recognized in a 9-day-old infant. The widening of the area of coarctation in the fifth arch with prostaglandin E 1 infusion without opening the ductus arteriosus is presented to document that ectopic ductal tissue constriction contributes to the development of coarctation in PFAA.
