The neonatal management of critical aortic arch obstruction in association with an arterial duct that remains closed or significantly constricted requires urgent surgical repair, with a postoperative focus on resolving the impaired function of compromised organs. Here, we present two neonatal cases illustrating the use of the dual arterial cannulation perfusion method in the complete repair of interrupted aortic arch and critical coarctation of the aorta with nonfunctional ductus arteriosus. We suggest that dual arterial cannulation, which provides total body perfusion (with the exception of cardiac perfusion during cardioplegic arrest of the heart), may be a good alternative to other perfusion strategies in cases of absent ductal blood flow, as this method allowed us to avoid the further development of severe multiple organ failure.
