摘要

Abstract

<正>Traumatic intracranial pseudoaneurysms（TIPA） are rare and pseudoaneurysm of P3 segment of the posterior cerebral artery（PCA） is extremely rarely reported.A 27-year-old man suffered from blunt head injury and underwent diagnostic procedure with head CT scans

cerebral CT angiograms（CTA） and digital subtraction angiograms（DSA）.An abnormal high-density lesion was detected at the left side of quadrigeminal cistern and a pseudoaneurysm showed at the P3 segment of PCA.The pseudoaneurysm was successfully treated with parent artery occlusion（PAO）.Making an exact preoperative diagnosis of traumatic intracranial pseudoaneurysms is of great importance.Endovascular techniques allow a safe approach to complex intracranial lesion

so endovascular management of PCA pseudoaneurysms becomes safe and effective.However

the pseudoaneurysm may not be amenable to coil placement under some conditions

thus

occlusion of the parent vessel may be a preferable treatment.
