Primary reconstruction of interrupted aortic arch by total aortic outflow obstruction

Primary aortic arch reconstruction was undertaken in three neonates with interrupted aortic arch and ventricular septal defect. Total ascending aortic occlusion without cardiopulmonary bypass or profound hypothermia permitted, in each case, a rapid tension-free end-to-side descending-to-ascending aortic anastomosis without resulting neurologic or cardiac sequelae. This technique offers distinct advantages over previously described methods and should be considered whenever interrupted aortic arch is present with a ventricular septal defect.
