[Carotid surgery for prophylaxis of ischemic stroke]

Area of Science:

• Vascular Surgery
• Neurology
• Cardiology

Context:

• Stroke is a leading cause of death and disability, with carotid artery stenosis being a significant risk factor.
• Extracranial carotid artery stenosis accounts for approximately 40,000 strokes annually.
• Carotid endarterectomy (TEA) is a proven intervention for stroke prophylaxis.

Purpose:

• To evaluate the effectiveness of carotid endarterectomy (TEA) in preventing ischemic stroke.
• To identify factors influencing the efficiency of carotid surgery.
• To compare surgical intervention with medical management for carotid stenosis.

Summary:

• Randomized studies confirm TEA's superiority over medical therapy (e.g., antiplatelet agents) for high-grade carotid stenoses.
• Despite proven benefits, TEA is currently underutilized, preventing only about 5% of potential carotid-related strokes.
• Optimizing TEA requires multidisciplinary collaboration, enhanced patient screening, advanced diagnostics, and increased surgical capacity.

Impact:

• TEA significantly reduces the risk of primary and secondary ischemic stroke in eligible patients.
• Increased utilization of TEA, through improved access and efficiency, could substantially decrease stroke incidence.
• Interventional methods like stenting require further validation before widespread adoption.
