摘要

Intracranial arterial occlusion is rarely encountered in association with head injury.Only six cases of traumatic occlusion of the anterior cerebral artery(ACA) have previously been reported.In this paper,the authors describe a case of a posttraumatic occlusion of ACA.A 35-year-old male presented to the emergency room with severe head injury.Computed tomography(CT) scan displayed diffuse brain swelling with multiple skull fractures.Follow up CT scan showed extensive cerebral infarction in the territory of ACA.The patient underwent CT angiography that demonstrated occlusion of the ACA by a fracture of the anterior fossa.He died after 3 d.ACA traumatic occlusion is a rare condition,with poor prognosis.In this case,fracture was responsible for dissection and direct obstruction of the artery.
