We report an unusual case of an 83-year-old man who was admitted with dizziness and repeated drop attacks. He was diagnosed with bilateral carotid artery occlusion and he underwent a left subclavian to left carotid bypass with ringed polytetrafluoroethylene graft. The patient's postoperative course was uneventful and no symptoms presented during a 6-month follow-up. Finally, we discuss on proper management of such patients.
