[Persistence of the 5 aortic arch associated with interruption of the aortic arch].

We report a case of persistence of the 5th aortic arch associated with total interruption of the aortic arch.

Preoperative clinical picture was misleading, due to the persistence of femoral pulses and clinical signs of left-to-right shunt via a wide ductus arteriosus.
