Fig 1 (A) Drawings and (B, C, D) arteriograms of the patient’s right-sided aortic arch, right-sided descending thoracic aortic aneurysm, and aberrant left subclavian artery. (B) Right anterior oblique (RAO) projection showing the right and left common carotid arteries arising from a common trunk. The right vertebral artery is dominant. (C) An RAO projection showing a left subclavian artery arising from a Kommerell’s diverticulum, which is particularly evident in the inset (arrow). The left vertebral artery is small. (D) A left anterior oblique view demonstrates the landing zone target immediately distal to where the right subclavian artery originates from the aorta. (a = artery; L = left; R = right.)
