Carotid artery occlusion

This study tests a metaverse-based surgical platform that uses extended reality (XR) to help surgeons precisely locate blood vessels during brain bypass surgery. The trial includes 30 adults with moyamoya disease or chronic cerebral ischemia who need an extracranial-intracranial …

This study compares two stomach-acid-lowering drugs—tegoprazan and rabeprazole—in about 3,300 heart disease patients who take blood thinners and are at high risk for stomach bleeding. The goal is to see if tegoprazan works as well as rabeprazole at preventing serious gut problems…

This study follows 1,200 people who received special fabric tubes (grafts) to repair or replace damaged arteries in the neck, belly, or legs. Researchers want to see how well the grafts work over time and how often problems like blockages or infections happen. It is an observatio…

This study tests whether a procedure to remove a blockage in the neck artery (endovascular treatment) plus standard medical care helps people recover better after a stroke. About 200 adults with acute ischemic stroke from a blocked internal carotid artery will be randomly assigne…

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 building a huge database of up to 800,000 Korean patients with heart or brain vascular disease. By tracking their health over many years, researchers hope to understand the unique patterns and risk factors in this population. The goal is to create a platform that ca…

This study collects blood, clots, and tissue from up to 1000 people having procedures for stroke or other blood vessel problems in the brain. Researchers will analyze these samples to find biological markers and understand inflammation. The goal is to learn more about how stroke …

This study tests a special microscope attachment called GLOW800 that helps surgeons see blood flow and tissues in real time during brain and reconstructive surgery. About 29 adults will take part, and surgeons will rate how well the tool works. The goal is to confirm the device i…

This early study is testing whether a robot can help doctors perform delicate brain blood vessel procedures, such as angiography, embolization, and thrombectomy. Ten patients scheduled for these standard procedures will have them done using a robotic system instead. The main goal…
