Carotid Artery Stenting clinical trials

Photon-Counting CT Versus Conventional CT for Carotid Plaque Assessment in Patients With Carotid Artery Stenosis

Treatment for stroke caused by blocked brain and neck arteries

This trial studies a procedure that opens blocked blood vessels in and behind the brain during a stroke, sometimes after standard clot-thinning medicine. It may help people who have brain tissue that can still be saved and a major blockage in both the neck and brain arteries.

Stent or procedure for narrowed carotid artery after neck radiation

This trial studies a carotid artery procedure (revascularization) to treat a major narrowing in the neck artery that happened after you had radiation for head or neck cancer. It may help prevent stroke risk by improving blood flow to the brain.

Opening blocked carotid artery for ongoing symptoms

This trial tests a procedure to open a blocked carotid artery in the neck to improve blood flow to the brain. It's for people who still have symptoms (like weakness or vision problems) despite medical treatment.

Predicting blood flow changes after carotid stenting

This study looks at why some people have too much blood flow to the brain after a procedure to open a blocked neck artery. It uses special tests to check how well your brain controls its own blood flow, with the goal of predicting and preventing problems.

Ultrasound monitoring during carotid artery stenting

This trial is testing a special ultrasound (called transcranial Doppler) to monitor blood flow during a procedure to open a narrowed carotid artery in your neck. The ultrasound helps doctors see if the procedure is safe and working well.

Comparing timing of carotid surgery or stenting after stroke

This trial compares the best timing for surgery or stenting to open a narrowed carotid artery after a minor stroke. The goal is to see if doing the procedure sooner or later reduces the chance of another stroke.

Compare surgery vs balloon/stent for re-narrowed neck artery

This trial compares two treatments for a carotid artery that has narrowed again after a prior stent: surgery (endarterectomy) versus repeat balloon treatment with or without stenting. It may help find which approach works better to prevent further narrowing and complications.

Shockwave balloon treatment for hardened carotid arteries before stenting

This study tests a special balloon that uses sound waves to break up calcium buildup in the carotid artery (the main artery in your neck) before placing a stent. It's for people who are at high risk for traditional surgery and have heavy calcium deposits in their artery.

Surgery vs stenting for recent stroke patients

This trial compares two procedures to open a blocked carotid artery in people who recently had a stroke. One option is surgery (carotid endarterectomy) to remove the blockage, the other is stenting (placing a small mesh tube to hold the artery open). The goal is to see which works better for patients still having some stroke symptoms.

Testing thinking and memory after carotid artery treatment

This study checks how a carotid artery procedure affects thinking and memory. You may be able to join if you’re an adult with significant carotid artery narrowing seen on ultrasound, and you can safely do follow-up MRI scans.

MicroNet-covered stent to prevent stroke in carotid procedures

This study tests a special stent (a small mesh tube) that may help prevent stroke during a carotid revascularization procedure. It’s for people with narrowing in the carotid artery, either recently symptomatic or very high-grade even without symptoms.

Predicting outcomes after stroke from artery plaque

This study looks at factors that can help predict recovery and risk after an ischemic stroke caused by plaque buildup in a major artery. It may help doctors better forecast prognosis and tailor follow-up care for people like you.

Stent plus heart surgery for high risk carotid patients

This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.

PET-MR scan study for narrowing in the carotid artery

This study tests how well a special PET-MR scan can help evaluate carotid artery plaque in people who have significant narrowing but no symptoms. It may help researchers better understand disease activity to guide treatment decisions like medication alone or medication plus surgery.

Carotid artery opening study for brain health

This study tests if opening a narrowed carotid artery can reduce brain damage from small vessel disease. It may help patients with carotid artery narrowing prevent cognitive decline.

Dual antiplatelet therapy after carotid artery stenting for high bleeding risk

This trial tests if taking two blood thinners (dual antiplatelet therapy) after a carotid artery stenting procedure is safe and effective for patients who have a higher risk of bleeding. It focuses on people with significant blockages in the neck arteries who are also at increased risk for serious bleeding or brain bleeds.

Carotid artery stenting during stroke clot removal

This trial tests whether placing a stent in a narrowed carotid artery during a procedure to remove a stroke clot improves outcomes. If you have a stroke with a blocked large artery and significant carotid narrowing, this study may be relevant to you.

Arm vs. Leg Artery for Carotid Stenting

This study compares two ways to reach the blocked neck artery during a stent procedure: through an artery in your arm versus one in your groin. The goal is to see which route is safer and works better for patients who need this treatment.

Testing a new carotid stent with blood-flow reversal for high-risk patients

This trial tests a new carotid stent system used with a special blood-flow reversal device to treat blocked carotid arteries. It is for people with high-risk conditions who might not be good candidates for traditional open surgery, and aims to see if the stent is safe and effective in preventing strokes.

Balloon guide catheter and filter protection for carotid stenting

This trial tests using a balloon guide catheter along with a filter to prevent debris from reaching the brain during carotid artery stenting. It may help people who have severe narrowing or blockage in the carotid artery and are getting a stent.

Shunt for carotid artery narrowing

This study tests a new device that is placed through the carotid artery in the neck to temporarily block blood flow during a procedure to open up a narrowed carotid artery. It might be an option for people who have high-risk features that make traditional surgery more challenging.

Study of a new shunt system for carotid artery blockage treatment

This trial tests a special shunt system to protect your brain during carotid artery stenting. It may help people with severe blockages in the neck artery that supplies blood to the brain.

PET/MR imaging for carotid artery plaque risk

This trial uses special PET/MR scans to look at fatty buildup in your neck arteries to see which ones might be dangerous. It could help doctors better understand your stroke risk and choose the right treatment.
