CAROTID ARTERY STENOSIS

This study looks at how long people at high risk of bleeding should take two blood thinners after having a carotid artery stent placed. About 1,556 participants will first take both aspirin and clopidogrel for 30 days, then be split into two groups: one continues both drugs for 1…

This study is testing a new stent system to treat narrowed carotid arteries (the main arteries in your neck) in people who are at high risk for standard surgery. The goal is to see if the stent is safe and effective at preventing strokes, heart attacks, and death. About 212 parti…

This study tests whether using ultrasound (TCD) during and after carotid artery stenting can reduce small brain injuries caused by clots. About 232 people with severe carotid artery narrowing will be randomly assigned to receive stenting with or without TCD. The goal is to see if…

This study compares two methods to protect the brain during a procedure to open a narrowed neck artery (carotid stenting). The standard method uses a small filter to catch debris, but some particles may still reach the brain. The new method adds a balloon that temporarily stops b…

This study tests whether a quick, routine ultrasound measurement (called the resistance index) can accurately identify people with narrowed neck arteries who have normal brain blood flow response. If it works, many patients could avoid a time-consuming, specialized test. The stud…

This study is testing whether a deep learning model can predict cerebral hyperperfusion syndrome (CHS), a rare but serious brain complication that can occur after carotid artery surgery. Researchers will enroll 500 adults aged 30-80 who are having carotid revascularization. The g…

This study tests whether a non-invasive digital cuff can accurately measure blood pressure continuously during carotid endarterectomy surgery, compared to the standard invasive arterial catheter. The goal is to see if the cuff can provide the same vital information without the ri…
