Aortic Arch Advancement and Ascending Sliding Arch Aortoplasty for Repair of Complex Primary and Recurrent Aortic Arch Obstruction

Abstract

The optimal treatment of patients with complex coarctation of the aorta and hypoplastic aortic arch is controversial. Children undergoing repair of obstructive arch lesions are at lifelong risk of recurrence. Multiple techniques have been described to address complex primary and recurrent coarctation. Our approach at Texas Children's Hospital (Houston, TX) has been to address these lesions in an anatomic fashion via median sternotomy, under cardiopulmonary bypass using the techniques of aortic arch advancement and ascending sliding arch aortoplasty. Anatomic repair of complex primary or recurrent aortic obstruction is safe and produces a favorable repair with a low rate of recurrence. Both operations restore normal arch contour using native aortic tissue. The decision of which particular surgical strategy to use depends on the patient's age, anatomy, and the elasticity of the tissue.
