What is Carotid stenting?
- Carotid stenting is when a small, expandable, thin wire device (called a stent) is placed into one of the main arteries that carries blood to the front part of the brain (carotid artery), as it has become partially blocked with abnormal thickening of the artery wall called 'plaque'.
- If the supply of blood to the brain is reduced, Carotid stenting can cause a stroke. The stent is placed in the artery, and then expanded to widen the artery to its normal size and smooth the inner surface to increase blood flow.
For What Carotid stenting is used?
- Carotid stenting is an alternative treatment to surgery (endarterectomy) or medical therapy that might include treatment to thin the blood to stop it from clotting (anticoagulation), as well as lifestyle management. The procedure can be carried out while a patient is awake or under a general anesthetic (asleep). Whether or not a general anesthetic is used is decided by the doctor carrying out the procedure, based on how complex the procedure is and the patient's medical condition.

Which doctor to be consulted for Carotid stenting?
1. Where is carotid stenting done?
Carotid stenting is performed in the angiography suite of a most of public and private hospitals.
2. What are the benefits of carotid stenting?
- Carotid stenting is performed in the angiography suite of a most of public and private hospitals.
- Carotid stenting avoids potential damage to nerves in the neck, such as the nerves involved with speech and swallowing, which can occur with surgery. The recovery period from an uncomplicated carotid stenting procedure would normally be quicker than uncomplicated surgery.
3. How long does carotid stenting take?
Carotid stenting can be completed within 30 minutes or can take up to 2 hours if the artery to be stented is difficult to access.
4. What are the risks of Carotid Stenting?
There are risks with carotid stenting. The main risk is of causing stroke during the stenting procedure. This occurs in between 2% and 10% of all carotid stenting procedures carried out. The risk of using carotid stenting to widen the artery is similar to the risk of having surgery (carotid endarterectomy). Carotid stenting would only be recommended when doctors believe patients are less likely to be at risk than if they had surgery.
