Video 31.3 Double aortic arch. Volume rendered three-dimensional magnetic resonance angiogram
Double aortic arch. Volume rendered three-dimensional magnetic resonance angiogram demonstrating approximately equal-sized left and right aortic arches. Note that the right arch is positioned slightly more superiorly than the left arch. The trachea and esophagus are not depicted in this rendering; they would both be positioned inside the ring formed by the aortic arches.
