Intracranial berry aneurysm

This study is testing a device called a flow modulator to treat wide-necked brain aneurysms. The device is placed inside the artery to redirect blood flow away from the aneurysm, helping it close off. Researchers will check if the device is safe and effective in 214 adults over 1…

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 early study tests a new device called the LuSeed Aneurysm Embolization System for treating unruptured brain aneurysms. The device is designed to block blood flow into the aneurysm, reducing the risk of rupture. About 30 adults aged 18-80 with unruptured saccular aneurysms wi…

This study is testing a new type of MRI scan called eASL that measures blood flow in the brain without needing a contrast injection. It will include 50 children with conditions like Moya-moya or sickle cell disease that affect brain arteries. The goal is to see if eASL gives clea…

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 collects blood and tissue samples from 400 people with brain aneurysms (some ruptured, some not) and 200 healthy volunteers. Researchers will analyze the participants' genes to find variations linked to a higher risk of aneurysm rupture. The goal is to create a tool th…

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…
