Right and left internal carotid artery angiograms. (A) Right internal carotid artery angiogram demonstrating the internal carotid artery dividing into middle and anterior cerebral arteries with the latter additionally supplying the left anterior cerebral artery territory. (B) Left internal carotid artery angiogram revealing the internal carotid artery branching into the middle carotid artery with absent contrast flow into the anterior cerebral artery territory. This may occur in vessel occlusion, but in this case it indicates an aplastic A1 segment.
