Traumatic intracranial pseudoaneurysms are uncommon and its incidence is about 1％ of all cerebral aneurysms. Bleeding due to vascular rupture caused by trauma can result in the formation of hematoma. which becomes organized and turns into a pseudoaneurysm that is communicated with vessels.Because traumatic pseudoaneurysms have no complete vascular wall. they are prone to be broken and thus cause bleeding. Therefore, the clinical treatment of pseudoaneurysms is different from the treatment of true intracranial aneurysms in some respects, and any operation, whether craniotomy or interventional embolization, takes high risk for patients with intracranial pseudoaneurysms. This paper aims to summary the therapeutic methods currently used in clinical practice and to make a detailed review of' endovascular management of intracranial pseudoaneurysms based on the pathological characteristics of pseudoaneurysms.
