1. Stroke prevention
   The primary benefit of CEA is its ability to significantly reduce the risk of stroke, particularly for those with severe stenosis. By removing plaque buildup that narrows the artery, CEA can improve blood flow to the brain, reducing the chances of a clot forming and blocking the vessel, which can lead to a stroke.
   
2. Symptom improvement
   Patients with carotid stenosis often experience symptoms like dizziness, vertigo or transient vision loss. These symptoms can arise due to reduced blood flow to the brain. CEA can alleviate these symptoms by restoring proper blood flow and improving brain function.
   
3. Improved quality of life
   By addressing the risk of stroke and potentially relieving existing symptoms, CEA can significantly improve a patient's quality of life. They can live with reduced anxiety about stroke, engage in activities previously limited by symptoms, and experience overall improved well-being.
   
4. Long-term protection
   The benefits of CEA extend beyond the immediate recovery period. The reduced risk of stroke remains significant over several years, providing long-term protection against this devastating event.

Potential Downsides of CEA

• Surgery risks: Any surgery carries inherent risks, including bleeding, infection, nerve damage and stroke. While uncommon, these risks should be carefully weighed against the potential benefits in individual cases.
• Recovery period: CEA requires a hospital stay and a period of recovery at home. This can disrupt daily routines and require support from caregivers.
• Long-term lifestyle changes: While CEA can effectively address the narrowed artery, managing underlying risk factors like high blood pressure, cholesterol and smoking remain crucial for long-term stroke prevention.
