Extracranial internal carotid artery pseudoaneurysm
Extracranial carotid artery aneurysms (ECAAs) are rare, with the etiology mainly classified as degeneration or dissection. Pseudoaneurysms in the region are even rarer and are seen following trauma, iatrogenic injury, or infection.
Experience with endovascular therapy of extracranial carotid artery pseudoaneurysm (ECAP) has been growing, and various results suggest it as a suitable treatment option.
Endovascular treatment of ECAP is safe and effective at improving symptoms. There were no perioperative or permanent neurologic sequelae in the 11 patients with follow-up, and all symptomatology related to ECAP improved or resolved with treatment 1).
