Ultrasound monitoring during carotid artery stenting
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 40 years old or older.
- You have severe narrowing of the internal carotid artery (the main artery in your neck).
- You are scheduled to have a stent placed in that artery.
- You are able to walk and take care of yourself (score of 2 or less on the Modified Rankin Scale).
- You have a good 'temporal window' for an ultrasound (so doctors can see blood flow in your brain).
- You have not had a major bleeding stroke in the last 90 days, and you do not have severe infections, bleeding problems, or other serious illnesses.

Other trials that look related to this one.
This trial tests if using a blood pressure cuff on the arm (to briefly restrict blood flow) before and after carotid stent placement can help reduce the risk of stroke. It is for people who have recently had stroke symptoms from a moderate to severe carotid artery blockage.
This study looks at using ultrasound to measure blockages in the arteries that supply the brain before a stent is placed. It aims to improve how these blockages are diagnosed.
This study tests a new technology that monitors blood flow in the neck during carotid endarterectomy, a surgery to clear a blocked artery that can cause stroke. The aim is to see if the device works safely and effectively in real patients.
This study tests a new way to measure pressure inside the carotid artery during a standard procedure to place a stent (a small mesh tube) to open a narrowed artery. The goal is to see if this pressure measurement can help doctors make better decisions during the procedure and possibly improve outcomes for people with carotid stenosis.
This trial tests whether using a balloon guide catheter during carotid artery stenting helps prevent strokes during the procedure. It is for people who have significant narrowing in the carotid artery in their neck.
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.
