Endovascular Repair of a Right-Sided Descending Thoracic Aortic Aneurysm With a Right-Sided Aortic Arch and Aberrant Left Subclavian Artery

Aneurysms involving a right-sided aortic arch and a right-sided descending thoracic aorta with an aberrant origin of the left subclavian artery are rare. We describe the successful surgical repair of this vascular anomaly by the combined use of a left carotid to subclavian artery bypass followed by endovascular stent-graft placement to exclude the aortic aneurysm. We also review the literature associated with this particular anatomic presentation.
