ANEURYSMAL SUBARACHNOID HEMORRHAGE

This early study tests whether a drug called sirolimus (rapamycin), given directly into the brain's fluid spaces, can prevent hydrocephalus after a severe brain hemorrhage. Hydrocephalus is a dangerous buildup of fluid that often requires a permanent surgical shunt. The trial wil…

This study tests whether a stellate ganglion block (a nerve block injection) can improve neurological outcomes in people who have had a bleeding stroke from a ruptured aneurysm. The procedure is done before surgery to reduce brain artery spasms and improve blood flow. Researchers…

This study looks at whether starting insulin to lower high blood sugar on day 4 after a severe stroke is better than starting on day 1. About 200 adults with severe stroke and high blood sugar will be randomly assigned to early or delayed treatment. The goal is to see if delaying…

This study tests a drug called tirofiban (Aggrastat) in 82 people who have had bleeding from a brain aneurysm. The drug is given through a vein to prevent blood clots that can cause delayed brain damage. The main goal is to find the safest dose, while also checking if it reduces …

This study tests whether a device that gently stimulates a nerve in the ear can reduce brain damage and inflammation after a traumatic brain injury or bleeding stroke. Sixty adults will be randomly assigned to receive either real stimulation or a sham (fake) treatment. Researcher…

This study tests whether the drug cilostazol can prevent delayed brain injury in people who have had a bleeding stroke from a burst aneurysm. About 316 adults will receive either cilostazol or a placebo for 14 days. The goal is to see if the drug reduces the risk of delayed brain…

This study tests whether adding cilostazol, a drug that improves blood flow, to standard nimodipine treatment helps people recover better after a brain aneurysm rupture. Researchers will enroll 630 adults in France within 96 hours of the bleed and follow them for 6 months. The go…

This study tests whether raising or lowering blood pressure after aneurysm repair improves outcomes in people with a brain bleed. 750 adults who had surgery within 72 hours will be randomly assigned to different blood pressure targets. Their recovery will be tracked for 6 months …

This study tests whether giving a calcium channel blocker (nicardipine) through a lumbar drain can prevent dangerous artery spasms and delayed brain damage in people who have had a brain bleed from a ruptured aneurysm. About 214 adults with mild to moderate bleeds will receive th…

This study will track 1000 adults who had a brain bleed from a burst aneurysm. The goal is to learn how often delayed brain injury happens and how doctors currently diagnose and treat it. By comparing different hospital approaches, researchers hope to find better ways to prevent …

This study looks at whether people who have had a ruptured brain aneurysm also have an abdominal aortic aneurysm (a bulge in the main belly artery) that they don't know about. About 233 participants will get a painless belly ultrasound to check. The goal is to see how common this…

This study looks at blood markers related to inflammation and clotting in people who have had a stroke or a brain bleed. Researchers want to see how these markers change over time and differ between patients with complications. About 499 adults will give blood samples at five tim…
