Double Aortic Arch

1)Certain factors pertaining to double aortic arch have been mentioned. 2)A case presenting a rare type of double aortic arch, previously unrecorded, has been reported. 3)The presence of a congenital vascular ring should be suspected in infants who suffer with stridor, dysphagia and associated symptoms. 4)Those patients with severe symptoms due to a constricting vascular ring will probably not survive if untreated. Surgery offers the only prospect of a cure. It has been demonstrated that young infants possess the ability to withstand major intrathoracic operative procedures surprisingly well. Operation should therefore be performed in these cases promptly after the diagnosis is established.
