title: Aneurysm arising from the petrous portion of the internal carotid artery: case report.
abstract: A 21-year-old man with hearing loss and recurrent otorrhagia was shown angiographically to have an aneurysm arising from the intrapetrous internal carotid artery (ICA). Endovascular balloon occlusion of the aneurysm with preservation of the parent ICA was attempted twice, but each time the balloon deflated and the aneurysm reappeared two weeks and three months, respectively, following the endovascular procedures. The patient was then successfully treated with a surgical trapping procedure combined with superficial temporal artery-middle cerebral artery bypass.
