Abstract:
Aberrant right subclavian artery (ARSA) is an uncommon congenital vascular abnormality. Acute Stanford type A aortic dissection with ARSA is rare. We report a strategy for Stanford type A aortic dissection with ARSA. The ascending aorta and the total aortic arch were replaced and a frozen elephant trunk was implanted into the descending aorta. The right subclavian artery was reconstructed with the perfusion branch of a four-branch prosthetic graft. Two weeks later, the proximal part of the ARSA was sealed with a vascular plug.
