“By combining advanced imaging, targeted interventions, and personalized treatment strategies, interventional radiology plays a crucial role in slowing the progression of chronic kidney disease and improving patient outcomes.”
– Dr. Fabio Komlos

Carotid artery disease is a serious vascular condition that can lead to stroke, one of the leading causes of disability and death worldwide. Traditionally, open surgery was the main treatment option, but advances in interventional radiology (IR) have transformed the way physicians manage this condition. Today, minimally invasive techniques such as carotid artery stenting are providing safer, more effective alternatives with faster recovery times.

What is Carotid Artery Disease?

Carotid artery disease occurs when plaque—a combination of fat, cholesterol, and other substances—builds up inside the carotid arteries. These arteries, located on both sides of the neck, are responsible for delivering oxygen-rich blood to the brain. Over time, plaque accumulation can narrow or block the arteries, restricting blood flow and increasing the risk of stroke.

Signs and Symptoms

Carotid disease often progresses silently until a serious event, such as a stroke or transient ischemic attack (TIA), also known as a “mini-stroke,” occurs. Symptoms may include:

  • Sudden weakness or numbness, usually on one side of the body
  • Difficulty speaking or understanding speech
  • Vision problems in one or both eyes
  • Dizziness or loss of coordination
  • Severe headaches with no known cause

If you or a loved one experience these symptoms, seek immediate medical attention.

How Interventional Radiology is Changing Treatment

Interventional radiologists specialize in minimally invasive, image-guided procedures that treat vascular conditions without the need for open surgery. When it comes to carotid disease, carotid artery stenting (CAS) has emerged as a game-changing alternative to traditional carotid endarterectomy (CEA).

Carotid Artery Stenting: A Minimally Invasive Approach

Carotid artery stenting involves placing a small mesh tube (stent) inside the narrowed artery to keep it open and improve blood flow. Here’s how it works:

  1. Imaging Guidance – Using advanced imaging such as fluoroscopy (real-time X-ray), the interventional radiologist inserts a catheter through a small incision, usually in the groin.
  2. Balloon Angioplasty – A tiny balloon is inflated to widen the narrowed artery.
  3. Stent Placement – A stent is deployed to support the artery and keep it open.
  4. Protection Against Stroke – A special filter device is often used to capture any dislodged plaque fragments, reducing the risk of stroke during the procedure.
Benefits of Carotid Artery Stenting Over Surgery
  • Minimally Invasive – Requires only a small incision, reducing the risk of complications.
  • Faster Recovery – Most patients go home the next day and resume normal activities sooner.
  • Reduced Stroke Risk – With embolic protection devices, the risk of stroke during the procedure is minimized.
  • Safer for High-Risk Patients – Ideal for patients who are not candidates for open surgery due to heart disease, lung conditions, or other health issues.
Who is a Candidate for Carotid Stenting?

Carotid stenting is often recommended for:

  • Patients with severe carotid artery narrowing (≥70%) with symptoms
  • Those at high risk for surgery due to age, medical conditions, or prior neck surgery
  • Patients with prior carotid endarterectomy who have recurrent narrowing (restenosis)

For individuals with mild or moderate narrowing, lifestyle changes and medications such as statins and blood thinners may be the first line of treatment.

Preventing Carotid Artery Disease

While medical advancements have improved treatment outcomes, prevention remains the best strategy. You can reduce your risk of carotid disease by:

  • Controlling high blood pressure – One of the biggest risk factors for artery damage.
  • Managing cholesterol levels – A heart-healthy diet and statins can help.
  • Quitting smoking – Smoking accelerates plaque buildup and damages arteries.
  • Exercising regularly – Helps improve circulation and reduce risk factors.
  • Maintaining a healthy weight – Reduces strain on the cardiovascular system.
Final Thoughts

Carotid disease is a serious but manageable condition, thanks to advances in interventional radiology. Carotid artery stenting is a powerful tool that provides a less invasive, highly effective option for patients at risk of stroke. If you or a loved one has carotid disease, consult a vascular specialist or an interventional radiologist to explore the best treatment options.

“With the advancements in interventional radiology, we can now treat carotid artery disease with minimally invasive techniques that significantly reduce the risk of stroke. Carotid artery stenting offers patients a safer alternative to open surgery, with faster recovery times and excellent long-term outcomes.”
