====== Extracranial internal carotid artery pseudoaneurysm ======


Extracranial [[carotid artery aneurysm]]s (ECAAs) are rare, with the [[etiology]] mainly classified as [[degeneration]] or [[dissection]]. [[Pseudoaneurysm]]s 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
