Efficacy of prostaglandin E1 in relieving obstruction in coarctation of a persistent fifth aortic arch without opening the ductus arteriosus.
Overview
abstract
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 E1 infusion without opening the ductus arteriosus is presented to document that ectopic ductal tissue constriction contributes to the development of coarctation in PFAA.
