Studying unstable plaque in the carotid artery

This trial studies the best way to treat people who have a high-grade blockage in their carotid artery but no symptoms. It focuses on blockages greater than 80% with signs of unstable plaque to prevent future strokes.

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.

This trial studies how blood flow and brain function change after a carotid artery revascularization procedure (opening a narrowed carotid artery). It may help doctors understand what to expect after treatment, especially in people with significant artery narrowing.

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.

This study looks at the makeup of plaque in the carotid artery (the neck blood vessel to the brain) in people who recently had a stroke caused by that narrowing. Researchers will use MRI and planned surgery to see which plaque components may matter for stroke risk and outcomes.

This trial tests a stent procedure to open a severely blocked carotid artery in people who have not had a stroke or mini-stroke from that blockage recently. It aims to see if the procedure is safe and effective for preventing future strokes.
