Digital subtraction angiography of right cervical aortic arch.

: This report describes a 7 year old boy with a history of recurrent respiratory infections, a 3/6 ejection systolic murmur and a right supraclavicular systolic thrill. Chest x-ray showed widening of the superior mediastinum towards the right, and barium esophagram demonstrated anterior displacement and compression of the esophagus. Cross-sectional echocardiography revealed a transverse aortic arch segment. Thus, the findings described above suggested the noninvasive diagnosis of the right cervical aortic arch. A peripheral intravenous digital subtraction angiography was necessary to evaluate the origin of the epi-aortic arteries and it proved adequate for the follow-up of these patients.
