Abstract
Pseudoaneurysm formation is a rare complication following carotid endarterectomy (CEA); however, its occurrence is associated with significant risk of morbidity. The patient in this report presented 2 years following CEA with headache and lateral neck mass. The diagnosis of a 3.5 x 3.0 cm carotid artery bifurcation pseudoaneurysm was made by using magnetic resonance angiography (MRA). Endovascular exclusion of the aneurysm was accomplished with coil embolization of the external carotid artery followed by deployment of a 7 x 50 mm wall stent graft into the common carotid artery-internal carotid artery (CCA-ICA). The patient's symptoms improved and at 6-months postexclusion, duplex ultrasound demonstrated a significant reduction in pseudoaneurysm size. This case highlights the feasibility and safety of using endovascular techniques in the treatment of post-CEA pseudoaneurysm.
