Carotid Stenting
What Is Carotid Stenting?
Carotid artery stenting (CAS) is a minimally invasive procedure used to treat narrowing or blockages in the carotid arteries, the major blood vessels that supply oxygenated blood to the brain. The procedure involves inserting a small, expandable metal mesh tube called a stent into the narrowed artery to help keep it open and improve blood flow. CAS is typically performed under local or general anesthesia and involves making a small incision either in the groin or neck area, through which a catheter is guided to the affected carotid artery. Once in place, a balloon is inflated to open the narrowed artery, and the stent is deployed to maintain the opening.
CAS is often recommended for patients who are considered high-risk for traditional carotid endarterectomy surgery, such as those with severe heart or lung disease, previous neck radiation or prior neck surgery. The procedure is effective in reducing the risk of stroke in patients with significant carotid artery stenosis (narrowing of 70% or more).
When To Consider Stent Carotid Artery?
The decision to consider carotid stenting is typically based on the severity of the stenosis and the patient’s overall health condition.
Carotid stenting is usually recommended for people with 50% stenosis and symptoms or 70% stenosis and no symptoms. Additionally, it is usually recommended for people who need to avoid more invasive surgeries. This may include people who have congestive heart failure, serious pulmonary disease, such as COPD, have experienced a recent heart attack or have a history of previous neck radiation.
How To Prepare for Carotid Stenting?
Before your carotid stenting procedure, you may need to undergo several tests to assess your overall health and the severity of your carotid artery stenosis. These may include imaging tests such as carotid ultrasound, CT angiography or magnetic resonance angiography (MRA). You may also be asked to make lifestyle changes, such as quitting smoking or adjusting your medications. It is important to inform your medical team about any allergies, medications or medical conditions you have to ensure a safe and successful procedure.
How Long Does Carotid Artery Stent Surgery Take?
Carotid artery stent surgery, a minimally invasive procedure used to treat carotid artery stenosis, typically takes about one to two hours. However, the duration can vary depending on the complexity of the case and the patient’s specific condition.
What Is the Recovery Time for Carotid Artery Stenting?
The recovery time for carotid artery stenting can vary depending on the individual’s health and specific circumstances.
Patients are usually monitored in the hospital for a short period. Most patients can expect to stay in the hospital for one to two days for monitoring and recovery. After discharge, patients may be advised to limit physical activity and attend follow-up appointments to ensure the stent is functioning properly.
Common Questions About Carotid Stenting
- What is the success rate of carotid stenting? Carotid stenting has been shown to be an effective treatment for carotid artery stenosis, with success rates comparable to those of carotid endarterectomy. Studies have reported a significant reduction in the risk of stroke following the procedure.
- How long does a carotid stent last? Carotid stents are designed to provide long-lasting support to the artery and maintain improved blood flow to the brain. With proper post-procedure care and management of risk factors, a carotid stent can remain effective for many years.
- Will I need ongoing monitoring after carotid stenting? Yes, regular follow-up appointments and monitoring are essential after carotid stenting to assess the stent's effectiveness and detect any potential complications early. Your vascular provider will schedule periodic check-ups, including imaging tests to evaluate the stent and the carotid arteries.
