† The occluded right CCA was recanalized by small vascular channels on follow-up angiogram. ‡ Good means a state of good preservation without restenosis of the stented artery. Numbers in columns of angiographic finding are percent stenosis of the arteries. Dizzi, dizziness; Vis Dist, visual disturbance; Sx, symptom; AVR, aortic valve replacement; p-com, posterior communicating arter; L, left; LCCA, left common carotid artery; LICA, left internal carotid artery; LVA, left vertebral artery; LSCA, left subclavian artery; N, normal; O, occlusion; RBCA, right brachiocephalic artery; RCCA, right CCA, RICA, right ICA; RVA, right VA; RSCA, right SCA. |
