Aneurysms of the carotid artery are rare with multiple underlying etiologies. Treatment is largely open surgery but medical and endovascular therapies have been used based on presentation, anatomy, and etiology. There is a moderate amount of retrospective case series data on surgical results but no prospective data or data comparing open versus endovascular therapy exists. Much research is still needed but difficult to obtain in this rare disease process.
