Rare branching pattern of the aortic arch in a neonate.

Here, we describe the case of a neonate who was found to have a complex pattern of branching on radiological imaging. The right common carotid artery, left common carotid artery and left subclavian artery were arising as a common single trunk from the arch of aorta with the additional presence of an aberrant right subclavian artery from the distal aortic arch on the left side and having a retroesophageal course to reach the right arm.
