Asymptomatic balanced-type double aortic arch in an elderly patient: a case report.

Double aortic arch is a congenital abnormality and sporadic cases have been reported in adult patients, who are usually diagnosed after complaining of asthma-like symptoms or swallowing difficulties because of the compression of the trachea or esophagus by the abnormal aortic arches. We present the case of a 67-year-old male patient with double aortic arch, found coincidentally during coronary angiographic examination.
