It is critical that traumatic intracranial pseudoaneurysms should be removed completely from the parent artery because there is a possibility of significant morbidity and mortality from the high risk of rebleeding from any remnants of the pseudoaneurysm. However, the deconstruction of the parent artery has the risk of ischemic damage to the distal to the trapped artery. We describe a case of a successful reconstructive stent-buttressed coil embolization in a patient with a traumatic pseudoaneurysm of the intracranial internal carotid artery. A 30-year-old man with a stuporous mentality was admitted to our institution after a traffic accident. The initial computed tomography scan showed a diffuse subarachnoid hemorrhage and a pseudoaneurysm of the left supraclinoid internal carotid artery. A reconstructive endovascular treatment using stent-assisted coil embolization with a stent-within-a-stent technique was conducted in order to save carotid blood flow. The pseudoaneurysm was completely obliterated and the patient recovered without any neurological deficit. We suggest that multiple stent placements with coiling may be considered as a treatment option for intracranial traumatic pseudoaneurysms as a reconstructive treatment.
