What Is Carotid Surgery and Stenting?
Carotid endarterectomy removes plaque through an incision in the neck. Carotid stenting treats narrowing from inside the artery using a catheter and stent. Both aim to reduce future stroke risk in appropriately selected carotid disease. The decision depends on whether the patient has had a recent TIA or stroke, degree of narrowing, age, anatomy, other illness and the procedural risk of the treating centre.
Who May Be Considered?
- Recent TIA or minor stroke linked to carotid narrowing
- Severe asymptomatic stenosis in a carefully selected patient
- Anatomy and health that favour endarterectomy
- High surgical-risk features that may favour a stenting approach
Assessment and Tests
- Neurological history and timing of symptoms
- Carotid Doppler confirmed with CT or MR angiography when needed
- Heart, kidney, medicine and anaesthesia review
- Comparison of medical therapy, surgery and stenting risk
How Treatment May Be Performed
Endarterectomy opens the artery and removes plaque directly
Stenting crosses the narrowing with catheter-based protection and support
Blood flow and neurological status are monitored closely
Antiplatelet and risk-factor treatment continue after either procedure
How to Prepare
Bring all brain and carotid imaging, discharge reports and a current medicine list. Antiplatelet instructions differ between surgery and stenting, so do not change aspirin, clopidogrel or anticoagulants without the treating team's direction.
Comfort and Anaesthesia Planning
Carotid endarterectomy may use general or regional anaesthesia. Carotid stenting commonly uses local anaesthesia with sedation. The safest plan depends on the procedure and patient.
What to Expect During Recovery
Hospital monitoring focuses on neurological changes, blood pressure and the access or neck wound. Return to normal activity is gradual and differs between surgery and stenting. Any new weakness, speech change, vision loss or severe headache after discharge is an emergency.
Risks and Limitations
The most important risks are stroke, heart complication, bleeding and death. Endarterectomy can also affect nearby cranial nerves or cause neck-wound problems; stenting has access-site and artery-related risks. Individual risk must be compared with stroke risk on medical therapy.
Alternatives to Consider
High-quality medical therapy includes antiplatelet treatment, cholesterol and blood-pressure control, diabetes care and tobacco cessation. Surveillance may be appropriate when narrowing, symptoms or expected benefit do not justify a procedure.
Follow-Up After Treatment
Long-term medicines and vascular risk control remain essential. Doppler surveillance checks for recurrent narrowing. A procedure treats one important stroke source but does not remove every cause of stroke.
