Abstract:
We report a case of persistence of the 5th aortic arch associated with total interruption of the aortic arch. This clinical case shows the diagnostic pitfall of the persistence of the 5th aortic arch and its beneficial hemodynamic effect. 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. The diagnosis was intraoperatively adjusted on the basis of blood pressure monitoring using catheter placed into the femoral artery.
