2 Fig. 1 Preoperative cerebral angiograms. A, Left EC-IC anastomosis at middle cerebral artery (arrow). B, Right EC-IC anastomosis at middle cerebral artery (arrow). C, Left external carotid stenosis (arrow) at cul de sac of occluded left internal carotid artery (arrow). D, Stenosis of right external carotid artery (arrow). E, Critical stenosis of left solitary vertebral artery (arrow). F, Postoperative magnetic resonance angiogram depicts transposition of vertebral artery to the side of common carotid artery (lower arrow). Upper arrow indicates branching of external carotid artery.
