Interrupted Aortic Arch
Survival in infants with this interrupted aortic arch depends on ductal patency for lower torso perfusion, so prostaglandin-E (PGE) infusion is always used during medical stabilization followed by immediate surgical repair. Repair of Type A interruption (interruption beyond the left subclavian artery) is performed through a left throacotomy. Associated anomalies [e.g., ventricular septal defect (VSD)] may be palliated with pulmonary artery banding through the same thoracotomy or repaired primarily working through a separate median sternotomy. Type B (interruption beyond left carotid artery) or Type C (interruption between innominate and left common carotid arteries) interruption and associated anomalies are repaired through a median sternotomy with cardiopulmonary bypass, deep hypothermia, and temporary low-flow cerebral perfusion.
