Traumatic Entrapment of the Anterior Cerebral Artery—A Case Report

Abstract

Traumatic entrapment of the anterior cerebral artery is an xtremely rare clinical entity and only one previous case is reported n the literature [1]. There are reported cases of entrapment of the ertebrobasilar artery in patients with longitudinal clival fractures 2]. In the 12 reported cases of vertebrobasilar artery entrapment, 6% (8/12) were identified at autopsy while the 4 other cases surived but with various neurologic deficits [2]. Traumatic cerebral infarction is rare with an incidence of .2–1.6% most common in the internal carotid artery, followed by he middle cerebral artery and then the vertebral and basilar arteres [3]. Traumatic infarction in the anterior cerebral artery territory s extremely rare. Fractures along the skull base are also known to potentially ause the formation of pseudoaneurysms due to direct vessel wall njury [1,4,5]. We present the extremely rare case of a traumatic ntrapment of the anterior cerebral artery, associated with small seudoaneurysms, along with our treatment strategy.
