(A) Three-dimensional computed tomographic angiography (CTA) reconstruction of the arch vessels with prominent tortuosity of bilateral carotid and vertebral arteries before ascending aortic, arch, and bilateral SCA repairs. (B) Three-dimensional CTA reconstruction of the hybrid repair with frozen elephant trunk (FET). Transposition of the left subclavian and vertebral arteries onto the left common carotid artery is patent at 1 year. CCA, common carotid artery; L, left; R, right; SCA, subclavian artery; VA, vertebral artery.
