Endovascular Repair of a Descending Thoracic Aortic Aneurysm With an Aberrant Left Subclavian Artery Associated With an Infrarenal Aortic Aneurysm

Aneurysms involving 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.
