Check a brain blood-flow test after carotid artery narrowing
Part of Injuries & trauma clinical trials.
This study tests how well a noninvasive ultrasound measurement (the Resistance Index) can show how well blood vessels in the brain respond to a medication. It may help doctors better assess brain blood-flow health in people with certain carotid artery blockages.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You agree to take part and sign an informed consent form
- You have health insurance coverage (or are a beneficiary)
- You have a severe (about 70% or more) blockage or blockage in the internal carotid artery on the neck (either without symptoms or with symptoms)
- On ultrasound, the side of your brain can be seen through the 'temple window,' and the middle brain artery (MCA) can be recorded on both sides
- You are not pregnant and are not breastfeeding

This study enrolls people age 40 or older who have at least 50% narrowing in one brain or neck (carotid) artery. It collects clinical information to better understand this condition and how patients are doing over time.
This study looks at new imaging markers in people with significant narrowing of the carotid artery (the main artery in the neck). It compares people who recently had a stroke from that artery with people who have no recent stroke, to better understand stroke risk and artery disease.
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 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.
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 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.
