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.

Les auteurs rapportent un cas de persistance du 5ème arc aortique associé à une interruption totale de l'arche aortique. Ce cas clinique montre le piège diagnostic posé par la persistance du 5ème arc aortique et son effet bénéfique hémodynamique. Le tableau clinique était trompeur en préopératoire en raison de la persistance des pouls fémoraux et des signes cliniques d'un shunt gauche-droite via un large canal artériel. Le diagnostic a été redressé en peropératoire grâce au monitorage de la pression artérielle par un cathéter placé dans l'artère fémorale.

Keywords: Persistence of the 5th aortic arch; abnormalities of the aortic arches; cardiac surgery; interruption of the aortic arch.
