Anomalous origin of the left innominate (brachiocephalic) artery in the right aortic arch: How can it be anomalous when the left innominate artery is absent?

Double Aortic Arch with Atresia of the Left Aortic Arch Proximal to the Left Common Carotid Artery: First Report of Documentation by Surgical Observation

Double aortic arch associated with atresia of the left arch proximal to the left common carotid artery has been considered a theoretical possibility. To our knowledge, we report the first patient with this anatomy confirmed by surgical observation.

Anomalous origin of the left brachiocephalic artery in the right aortic arch: Is there a method to the madness?

The anomalous origin of the left brachiocephalic artery in a right sided aortic arch is a rare vascular ring which might lead to esophageal compression. The exact embryological origin of this anomaly is still widely debated. We present an infant who presented with esophageal compression symptoms and review the various hypotheses about the embryological origin of this anomaly.
