The Department of Cardiac Sciences at Vimhans Nayati Super Speciality Hospital is a hub of Excellence pioneering Innovation and Technology to offer unparalleled treatment and care to the patients. The department is managed by a dedicated team of some of the best cardiac doctors and surgeons in the country who offer a wide gamut of treatment under the same roof. Our areas of expertise include carotid stenting. The procedure aims at treating narrowed or blocked carotid arteries so as to restore the normal flow of blood to the brain. Carotid stenting is done with carotid angioplasty and is a gold standard option for treating and preventing strokes.
Why is the procedure performed?
The carotid arteries are a pair of arteries present on either side of the neck and are responsible for supplying oxygenated blood to the brain. Sometimes, these can get clogged due to plaque formation, which in turn hinders the normal flow of blood to the brain and increases the risks of a stroke. Carotid stenting involves the use of a small metal coil or stent to open the clogged artery and prevent the passage from narrowing back. The procedure is highly recommended to patients who cannot undergo conventional carotid surgery. However, it is important to understand that carotid stenting is not an option for everyone and may be recommended for any of the following cases:
- 70 percent of the carotid artery is blocked and the patient is showing symptoms related to stroke.
- Restenosis after carotid endarterectomy
- Area of stenosis cannot be accessed with carotid endarterectomy
Preparing for Carotid Stenting
Prior to carotid stenting, you will be required to undergo certain screenings and tests to make sure that you are eligible for the procedure as well as to determine a proper course of treatment.
Your doctor will perform a detailed physical exam followed by tests like ultrasound, MRA (Magnetic resonance angiography), CTA (computerized tomography angiography), and carotid angiography.
It is important to inform your doctor about your medical history, including any surgery that you have had in the past.
If you are taking any medication presently, make sure that your doctor knows about these as you might need to alter the dosage or stop taking them.
What happens during the procedure?
- The procedure is carried out under the influence of anaesthesia. Doctors clean the surgical site and make a tiny incision to introduce a catheter fix with a balloon on one of its ends.
- The catheter is carefully directed towards the affected artery with the help of imaging guidance which involves the use of X-rays and contrast material.
- A tiny filter, known as an embolic protection device, is also inserted along with the catheter so as to catch any debris that might break off during the procedure.
- Once the catheter is in the right position, the balloon is inflated to open the walls of the narrowed artery and pave way for the placement of the mesh tube or stent.
- After the procedure is completed, the catheter is removed along with the balloon, sheath and filter and the surgical site is closed.
What to expect post Carotid Stenting?
After the procedure, you will be required to lie still for some time so as to negate the risks of bleeding from the site of the incision. You will be kept under observation for several hours and then shifted to your room. Patients are usually discharged within 5 to 6 days. The patient should avoid indulging in any rigorous physical activity and follow the given set of guidelines religiously.
