Double arc aortique: à propos de deux cas

Double aortic arch is a rare anomaly of the aortic arch. It is due to the absence of involution of the caudal dorsal aorta. The disease usually begins to show itself in very early clinical signs, already detectable in the neonatal period. Angiography is of great interest to its diagnosis as well as to the choice of the therapeutic approach. Only surgical treatment allows to eliminate tracheoesophageal compression. Surgical mortality rate is low thanks to the progress of postoperative resuscitation. We here report two cases of double aortic arch in order to highlight the contribution of imaging in the difficult diagnosis of this anomaly.
