Abstract

WE PRESENT THE case of a patient with an aneurysm of the right internal carotid artery with subarachnoid hemorrhage. The aneurysm had resulted in erosion of the anterior clinoid process, but this was not recognized preoperatively. Intraoperative rupture during drilling of the clinoid necessitated vigorous packing that led to unintended carotid occlusion with subsequent fatal cerebral infarction. Preoperative recognition of the clinoid erosion may have prevented this catastrophe. To call attention to the potential for intraoperative rupture during exposure, we suggest the term subclinoid aneurysm to refer to aneurysms of the internal carotid artery that grow superolaterally and remain confined under the anterior clinoid process.
