Iatrogenic basilary artery aneurysm: A rare vascular complication of transshphenoidal transmaxillary surgery: Case report [Yatrojenik baziler arter anevrizması: Transmaksiller transsfenoidal cerrahinin ender komplikasyonu: Olgu sunumu]

Vascular injury to structures adjacent to the sphenoid sinus and rostral clivus is a rare complication in transsphenoidal surgery. carotid and basilar artery injury can be disastrous because of difficulty to obtain a proximal control. if an intraoperative injury is well controlled,a postoperative arteriography is necessary to search for a pseudoaneurysm. the rupture of all three layers of artery accompanied by an organized hematoma results in a false aneurysm (1,2). this is the first case report in literature describing a basilar artery pseudoaneurysm after extracranial tansmaxillary approach to a clivus tumor. © 2014,ege university press. all rights reserved.
