Congenital aortic arch anomalies: contrast enhancement MRA and DSA diagnosis

Objective To report 115 cases of congenital aortic arch anomalies, and to evaluate the imaging diagnostic techniques. Methods One hundred and fifteen patients with congenital aortic arch anomalies underwent angiocardiography and(or)contrast enhancement magnetic resonance angiography (CE MRA). Results In this 115 cases, double aortic arch was seen in 5 cases, right aortic arch with aberrant left subclavian artery in 45 with isolated left subclavian artery in 11, left aortic arch with aberrant right subclavian artery in 33, right aortic arch with left descending aorta in 7, left aortic arch with right descending aorta in 4, cervical aorta in 4, and others in 6. Conclusion CE MRA is a reliable noninvasive imaging diagnostic method.
