Right cervical aortic arch associated with anomaly of epiaortic vessels and haemodynamically significant obstruction between ascending and descending aorta. Extra-anatomic bypass graft between ascending and descending aorta and long-term follow-up.

Right cervical aortic arch is a rare malformation in which a right-sided aortic arch is unusually long, forms a loop, descends, and crosses behind the oesophagus to continue as a left descending aorta. We present a case of right cervical aortic arch associated with anomaly of epiaortic vessels and aortic obstruction, surgically treated with extra-anatomic bypass graft between ascending and descending aorta.
