Transfemoral cerebral angiography was performed in four children with brain death secondary to increased intracranial pressure. Findings not previously described are filling of the cavernous, petrous and cervical portions of the contralateral internal carotid artery via the anterior communicating artery, filling of the basilar and vertebral arteries via the posterior communicating artery and anterior displacement of the basilar artery.
