Case 1 is of a patient undergoing evaluation of an infrarenal aortic aneurysm stent graft. Computed tomography (CT) angiogram revealed an aberrant right vertebral artery that subsequently joined a second right vertebral artery that had the typical origin off the right subclavian artery. This represents an unusual anatomic variation not previously reported in the literature. Case 2 is of a patient being evaluated for thoracic aorta injury. CT angiogram of the chest revealed a five-vessel aortic arch with aberrant origin of the bilateral vertebral arteries distal to the left subclavian artery.
