A 68-year-old woman with right aortic arch and aberrant left subclavian artery was urgently operated for type A aortic dissection. Surgical management included total arch repair with frozen elephant trunk technique and left subclavian artery re-implantation. Post-operative course was complicated by severe renal failure, delirium and pneumonia. She was re-operated 3 weeks later due to an expanding proximal aortic anastomosis pseudoaneurysm. Right aortic arch is a rare vascular anomaly requiring thoughtful preoperative planning for adequate myocardial, cerebral and spinal protection. Frozen elephant trunk facilitates management of extensive dissection, relieves malperfusion and may alleviate the need for subsequent operations.
