Carotid-Carotid Bypass for a Carotid Artery Aneurysm

Abstract

Background: Surgical treatment for symptomatic extracranial carotid artery aneurysms should be encouraged because of their high recurrence rates.

Case description: A 55-year-old man presented with progressive right-sided hemiparesis and dysarthria. Computed tomography angiography revealed the cause of his repeated cerebral infarction was due to the distal emboli from an intra-aneurysmal thrombus of a giant thrombosed aneurysm at the origin of left common carotid artery. Right common carotid artery-saphenous vein graft-left common carotid artery bypass followed by left common carotid artery ligation was successfully performed.

Conclusions: Carotid-carotid bypass followed by common carotid artery ligation is an optional procedure for symptomatic proximal common carotid artery aneurysm.
