[Right cervical aortic arch: report of 2 cases, one associated with aortic coarctation]

Cervical aortic arch is a rare congenital vascular anomaly. Usually it appears as an asymptomatic pulsatile cervical mass, but symptoms of tracheal and esophageal compression may be present in 25% of the patients. About 40% of cases are associated with vascular or heart abnormalities. Angiography provides definitive diagnosis. Authors report two patients with right cervical aortic arch, one of them associated with aortic coarctation, and review 52 published cases.
