Ipsilateral subclavian to external carotid and STA-MCA bypasses for retinal ischemia

The surgical treatment of a patient with retinal ischemia in the left eye and occlusion of the left common and internal carotid and right internal carotid arteries is presented. After demonstration of filling of the left external carotid artery from vertebral collaterals, as saphenous vein graft from the left subclavian to the left external carotid artery was performed prior to a left superficial temporal artery to middle cerebral artery bypass. This case demonstrates the feasibility of revascularization in the presence of occlusion of the ipsilateral common and internal carotid arteries.
