Extracranial carotid artery aneurysm (ECAA) is extremely rare, accounting for only 0.4-4% of all
peripheral artery aneurysms. Sir Astley Cooper is credited with the first successful operation for ECAA in
1808.
These aneurysms are of interest becau
se they have diverse etiologies and present diagnostic and
therapeutic challenges. The symptoms of ECAAs vary according to their location, size, and etiology. The
presentation of such aneurysms may vary from an asymptomatic mass in the neck to the development of a
permanent neurological deficit as a consequence of micro emboli arising from within the aneurysmal sac.
Although most carotid artery aneurysms are caused by atherosclerosis, other common causes include
trauma and infection.
Carotid artery aneurysms are usually diagnosed by means of ultrasonographic scanning. Additional
diagnostic testing -by computed tomographic angiography, or magnetic resonance imaging- can lead to
more accurate information on the aneurysm’s size and its relationship to surrounding structures.
We herein report an extra cranial carotid artery aneurysm detected in a 46 years old patient with
complaint of neurologic Symptoms. Because aneurysm located in the distal ICA, the treatment involved
stent graft deployment. There has been no complications noted during the 10 months follow up after
treatment.
In conclusion, Extra Cranial Carotid Artery Aneurysm is a rare condition and has high rate of
complication with conservative approach.
