Endovascular Treatment of Traumatic Pericallosal Artery Aneurysms

Traumatic intracranial aneurysms are rare complications of closed and penetrating head injuries 1,2. With blunt head trauma, the most common location of a traumatic aneurysm is the internal carotid artery by laceration of the vessel following fracture of the skull base. The pericallosal artery is another common location with laceration of a distal pericallosal artery branch under the sharp edge of the falx cerebri. Traumatic intracranial aneurysms are fragile, prone to rupture, and represent a challenging subset of vascular lesions for either surgery or endovascular therapy. This report presents two patients with blunt head trauma and traumatic pericallosal artery aneurysms treated by endovascular parent vessel occlusion.
