Carotid Stenting is a minimally invasive procedure used to treat narrowing (stenosis) of the carotid arteries—the two major blood vessels in the neck that supply blood to the brain. When these arteries become narrowed due to plaque buildup (atherosclerosis), the risk of stroke increases significantly.
At CARE CHL Hospital, Indore, under the guidance of renowned Interventional Neuroradiologist Dr. Alok K. Udiya, we offer advanced Carotid Artery Stenting (CAS) as an effective alternative to open surgical procedures. Our team uses high-end neurointerventional techniques that ensure precision, safety, and a faster recovery for patients at risk of stroke.
Key Benefits of Carotid Stenting
Carotid stenting is a lifesaving option for individuals at high risk of stroke. Here are some major advantages:
- Minimally invasive—no open surgery required
- Shorter hospital stay and faster recovery
- Effectively reduces stroke risk in patients with carotid artery disease
- High-precision real-time imaging for safe stent placement
- Especially beneficial for patients who are unfit for surgery
- Can be performed immediately following diagnostic cerebral angiography
How This Treatment Works
Carotid artery stenting involves the use of catheter-based techniques to open a blocked artery and place a stent, helping maintain normal blood flow to the brain. Here’s how the process works:
1. Diagnosis and Evaluation
Before the procedure, patients undergo imaging tests such as Doppler Ultrasound, CT Angiography, or Cerebral Angiogram (DSA) to confirm the extent of carotid stenosis. Stenosis of 70% or more is generally considered for intervention.
2. Pre-Procedure Preparation
Patients may be started on blood thinners like aspirin or clopidogrel several days before the procedure. Pre-anesthesia evaluations and fasting for 6–8 hours are typically recommended.
3. The Procedure
The procedure is performed in an angiography suite:
- A catheter is inserted through the femoral artery (groin) or radial artery (wrist).
- The catheter is guided under fluoroscopy to reach the carotid artery.
- A cerebral protection device (filter) is placed to prevent embolization during the procedure.
- Balloon angioplasty may be used to open the narrowed segment.
- A stent is deployed to keep the artery open permanently.
- Post-deployment imaging ensures proper blood flow and stent placement.
4. Post-Procedure Recovery
Patients are monitored for several hours or overnight. Most are discharged within 24–48 hours with specific medication and follow-up instructions. A Doppler ultrasound is used at intervals to monitor stent patency.

FAQs – Carotid Artery Stenting
Q1. Who is a candidate for carotid stenting?
Patients diagnosed with significant narrowing (usually above 70%) in the carotid arteries, especially those with previous mini-strokes (TIAs) or who are unfit for surgery, are ideal candidates.
Q2. Is carotid stenting better than surgery?
For patients who are at high risk for surgery, carotid stenting is equally effective and less invasive. For others, the choice depends on the individual case and overall health profile.
Q3. How long does the procedure take?
Typically, the procedure lasts 1 to 2 hours, followed by a period of observation and post-operative care.
Q4. What are the risks associated with carotid stenting?
Complications are rare but can include bleeding at the catheter site, stroke, or re-narrowing of the artery. Risk is minimized in experienced hands and with the use of protective devices.
Q5. Is the stent permanent?
Yes, the stent is designed to remain in the artery permanently. Patients are usually placed on medication to prevent blood clots and are followed up regularly.
Q6. Will I be able to resume my normal activities?
Most patients resume normal activities within a few days of the procedure, though strenuous exercise may be restricted temporarily.
Q7. What lifestyle changes are needed post-procedure?
Smoking cessation, healthy diet, regular exercise, and strict adherence to medications are key to preventing recurrence
