A team of Dutch researchers is undertaking a study to determine the optimal surgical technique for treating carotid artery stenosis, a major cause of stroke. The research focuses on understanding how blood flow dynamics following surgery impact long-term outcomes.
Roughly 3,000 procedures are performed annually in the Netherlands to address carotid artery narrowing, or stenosis.The study, spearheaded by Prof. michel Reijnen of the University of Twente and Dr. Anne Saris of Radboudumc, compares two common surgical approaches. Janna Ruisch, a doctoral student at Rijnstate, Radboudumc, and the University of Twente, is leading the research efforts. “Our aim is to identify which surgical method provides the best outcome for patients,” Ruisch said.
Understanding Plaque Formation
Ruisch explained that plaque accumulation on the inner walls of arteries causes the narrowing. This often occurs where the vessel branches,creating varied resistance to blood flow.The danger arises when plaque dislodges, traveling to the brain and obstructing blood vessels, leading to a stroke.
“Detecting the cause of the stroke is crucial,” Ruisch said, “as further plaque release can trigger subsequent strokes. Surgery to remove plaque from the carotid artery is performed to prevent this.”
Two surgical Techniques Under Scrutiny
Currently,two primary surgical methods exist for carotid artery plaque removal:
- Carotid Endarterectomy with Patch Angioplasty (CEAP): This involves removing the inner layer of the artery and widening the vessel with a patch made of either the patient’s tissue or synthetic material.
- Eversion Technology (ET): this technique involves a different incision approach, where the diseased inner layer is removed from inside the artery without needing a patch.
each method presents distinct advantages and disadvantages. Post-surgery, patient blood flow is monitored using a novel ultrasound technique capable of capturing approximately 10,000 images per second, a significant leap from the 100 images per second possible with current systems, according to Ruisch. This allows researchers to precisely track red blood cell movement and map blood flow in detail, a method known as Velocity Vector Imaging (VVI).
Initial Findings Suggest Blood Flow Changes
Early results indicate altered blood flow patterns in many patients who underwent the patch technique. Researchers observed a rotating blood movement, or recirculation, within the operated vessel, potentially linked to the surgical technique itself. This observation prompted further examination into blood flow patterns in patients undergoing ET.
while existing literature suggests a higher risk of recurrent narrowing with the patch technique,researchers aim to determine if altered blood flow following surgery contributes to this increased risk.
The study will continue to monitor patients from Rijnstate, Radboudumc, Elisabeth TweeSteden Hospital (ETZ), and medisch Spectrum Twente (MST) to identify differences in blood flow between CEAP and ET procedures. The ultimate goal is to determine which surgical technique offers the best long-term outcomes for patients.
Ruisch anticipates completing her doctoral research in 2026.The findings could potentially inform the application of this advanced imaging technique to other blood vessels throughout the body.
In October,Charlotte Nawijn,also from the University of Twente (UT),earned her doctorate for developing a new ultrasound technique using “smart pulse train” technology to enhance blood flow.
Dutch Researchers Compare Carotid Artery Procedures: Your Questions Answered
What is the carotid artery and why is it vital?
The carotid arteries are major blood vessels in your neck that supply blood to your brain. They’re essential for delivering oxygen and nutrients to keep your brain functioning properly. When these arteries narrow, it can lead to serious health issues.
What is carotid artery stenosis?
Carotid artery stenosis refers to the narrowing of the carotid arteries. This narrowing is most often caused by the buildup of plaque (a substance made up of cholesterol, fat, and other substances).The plaque accumulation on the inner walls of the arteries causes the narrowing because it often occurs were the vessel branches, creating varied resistance to blood flow as explained by Janna Ruisch, a doctoral student involved in the research.
What are the risks of carotid artery stenosis?
The main danger of carotid artery stenosis is stroke. When plaque dislodges from the artery, it can travel to the brain and block blood vessels, leading to a stroke. This is why detecting the cause of a stroke early on is critical, as further plaque release can trigger subsequent strokes.
How common is carotid artery stenosis and how many procedures are performed in the Netherlands?
Carotid artery stenosis is a significant health concern. In the Netherlands,roughly 3,000 procedures are performed annually to address carotid artery narrowing,or stenosis.
What surgical methods are used to treat carotid artery stenosis?
Currently, two primary surgical methods exist for carotid artery plaque removal: Carotid Endarterectomy wiht Patch Angioplasty (CEAP) and Eversion Technology (ET). These methods, which are being compared by Dutch researchers, aim to prevent strokes caused by carotid artery stenosis.
What is Carotid Endarterectomy with Patch Angioplasty (CEAP)?
CEAP involves removing the inner layer of the artery where the plaque has accumulated. Following plaque removal, the vessel is widened with a patch. This patch can be made from either the patient’s own tissue or a synthetic material.
What is Eversion Technology (ET) for carotid artery plaque removal?
ET is a technique that involves a different incision approach, where the diseased inner layer is removed from inside the artery without needing a patch.
What are the advantages and disadvantages of each surgical technique?
The provided article doesn’t explicitly list the advantages and disadvantages but implies each method has its own set of pros and cons. The Dutch research aims to identify which method gives the best long-term outcomes.
What is the focus of the Dutch research on carotid artery procedures?
A team of Dutch researchers is conducting a study to determine the optimal surgical technique for treating carotid artery stenosis, aiming to improve stroke prevention. The research focuses on understanding how blood flow dynamics following surgery impact long-term patient outcomes.
Who is leading the research?
The study is led by Prof. Michel Reijnen of the University of Twente and Dr. Anne Saris of Radboudumc. Janna Ruisch, a doctoral student at Rijnstate, Radboudumc, and the University of Twente, is leading the research efforts.

can you summarize the key differences between the two surgical methods?
Certainly, here’s a rapid comparison:
| Feature | Carotid Endarterectomy with Patch Angioplasty (CEAP) | Eversion Technology (ET) |
|---|---|---|
| Procedure | Removes inner artery layer, widens with patch (patient tissue or synthetic) | Removes diseased inner layer from inside the artery, no patch needed |
| Blood Flow | Early results show altered flow patterns (recirculation) | Under investigation |
| Goal in research study | To understand blood flow dynamics and long-term outcomes | To evaluate differences in blood flow and long-term outcomes |
