Carotid-Carotid Bypass for a Carotid Artery Aneurysm

Area of Science:

• Vascular Surgery
• Cerebrovascular Disease
• Interventional Neurology

Background:

• Extracranial carotid artery aneurysms can lead to severe neurological deficits.
• Symptomatic aneurysms carry a high risk of recurrence, necessitating effective treatment.
• Giant thrombosed aneurysms pose a significant risk of embolic events.

Observation:

• A 55-year-old male presented with hemiparesis and dysarthria.
• Computed tomography angiography identified a giant thrombosed aneurysm at the left common carotid artery origin.
• Distal emboli from the aneurysm were the cause of recurrent cerebral infarction.

Findings:

• A successful surgical intervention was performed, involving a right common carotid artery-saphenous vein graft-left common carotid artery bypass.
• The procedure was followed by left common carotid artery ligation.
• This combined approach effectively managed the symptomatic aneurysm and prevented further embolic events.

Implications:

• Surgical bypass and ligation is a viable option for managing symptomatic proximal common carotid artery aneurysms.
• Early surgical consideration can prevent devastating neurological consequences like stroke.
• This case highlights the importance of timely intervention for complex cerebrovascular pathologies.
