Figure 2 Intracranial Angiograms of the Same Patient in Figure 1
(A) Initial ipsilateral common carotid artery injection, showing only opacification of external carotid artery branches. (B) Initial contralateral common carotid artery injection with collateral opacification of left anterior (white arrows) and middle cerebral (dark arrowheads) arteries via anterior communicating artery. (C) Final left common carotid artery injection showing restoration of normal antegrade flow.
