Traumatic intracranial aneurysms don’t belong to the common complications of traumatic brain injury, but its mortality rate is extremely high, which acts as an important cause of delayed death. The highest risk of traumatic intracranial aneurysm rupture was happened at 2-3 weeks after injury, probably it’s presented as sudden intracranial hemorrhage, subarachnoid hemorrhage or epistaxis. Early intracranial angiography was needed among the brain trauma patients suspected with aneurysm. As traumatic intracranial aneurysms are mainly pseudoaneurysms, lacking the complete vascular wall and neck are lacked, and their clinical treatment is different from the spontaneous aneurysms. In addition to the craniotomy, simple coil embolization, stent assisted coil embolization, covered stent and low porosity flow guide device mean to have been applied in the treatment of traumatic intracranial aneurysms. The risk factors pathogenesis, classification and treatment methods of traumatic intracranial aneurysm were reviewed, and the experiences of two cases of traumatic and iatrogenic intracranial aneurysms were shared in this paper.
