OBJECTIVE: Extracranial carotid artery aneurysm is a rare vascular disease. In this study, we present our experience with extracranial carotid artery aneurysm and we review the related articles with addressing different treatment options and their results.
Between 2003 and 2011, 11 patients (mean age : 52.7 years) were diagnosed to harbor extracranial carotid artery aneurysms. Five patients underwent various surgeries and 2 patients were treated by endovascular methods. Four patients were managed conservatively.
There were no perioperative/periprocedural mortality or morbidity related to the treatment of extracranial carotid artery aneurysms. During follow-up (mean follow-up : 39.3 months), 1 patient died of an unrelated cause and 2 other patients underwent stenting and/or angioplasty due to asymptomatic progressive stenosis of the treated site.
Aneurysm can be treated with low periprocedural risk by utilizing various therapeutic modalities. Long-term follow-up is mandatory to check for stenosis around the treatment site.
