Aortic arch and frozen elephant trunk repair of a right-sided aortic arch with pseudoaneurysm rupture

A 53-year-old man with a history of vascular ring repair secondary to a right-sided aortic arch with a retroesophageal subclavian artery and ligamentum arteriosum to the descending thoracic aorta presented to our institution with a large aortic pseudoaneurysm of the distal aortic arch. Computed tomography demonstrated a right-sided aortic arch with a 5.8-cm pseudoaneurysm arising from the distal arch with concern for rupture. The patient underwent successful two-stage repair, including a left carotid artery to subclavian artery bypass, followed by total arch replacement with the frozen elephant trunk technique. He recovered well postoperatively, and computed tomography showed complete, successful repair of the pseudoaneurysm.
