Management of carotid artery stenosis: comparing endarterectomy and stenting

Area of Science:

• Vascular Neurology
• Interventional Cardiology

Background:

• Stroke is a leading cause of death and disability, with significant economic impact.
• Cervical internal carotid artery occlusive disease accounts for approximately 25% of ischemic strokes.
• Carotid stenosis increases stroke risk through embolism and hypoperfusion.

Purpose of the Study:

• To review the established role of carotid endarterectomy (CEA) in stroke risk reduction.
• To introduce carotid angioplasty and stenting (CAS) as a contemporary alternative to CEA.
• To highlight patient populations where CAS may be preferred over CEA.

Main Methods:

• Review of landmark clinical trials including NASCET, ECST, and ACAS.
• Discussion of the evolution and application of carotid angioplasty and stenting (CAS).
• Comparative analysis of CEA and CAS in managing carotid stenosis.

Main Results:

• CEA has demonstrated substantial stroke risk reduction in specific grades of carotid stenosis.
• CAS has emerged as a viable alternative to CEA.
• CAS may be particularly beneficial for patients with increased CEA complication risks.

Conclusions:

• Carotid endarterectomy remains a proven intervention for select patients with symptomatic carotid stenosis.
• Carotid angioplasty and stenting offers a valuable alternative, especially in high-risk surgical candidates.
• Both CEA and CAS play crucial roles in managing carotid atherovascular disease to prevent ischemic stroke.
