Brain edema

This trial tests whether a gentle electrical earpiece, worn twice daily for two weeks, can reduce brain swelling caused by radiation necrosis. The device stimulates a nerve in the ear to calm inflammation. Forty people with brain tumors who need a laser procedure will be randomly…

This trial tests whether the Adacolumn device, which filters certain white blood cells from the blood, can reduce brain swelling in people who have had a severe stroke. Ten patients will receive the treatment within 24 hours of their stroke. The goal is to see if it prevents wors…

This study tests whether the drug butylphthalide can reduce brain swelling in people who have had a severe stroke and undergone a procedure to reopen a blocked artery. About 100 adults will receive either the drug or a placebo for up to 14 days. Researchers will measure changes i…

This study tests a new surgical technique called Expansion-floating Craniotomy (EC) for people with life-threatening brain swelling after a massive stroke. The standard surgery removes a piece of skull to relieve pressure, but requires a second surgery months later to replace the…

This study compares high-volume versus standard plasma exchange in 60 patients with acute liver failure and brain swelling (cerebral edema). The goal is to see if exchanging more plasma (8-9 liters) reduces brain swelling faster and improves survival without a liver transplant. R…

This early-stage study tests whether a device that gently stimulates a nerve in the ear is safe and practical for people with moderate to severe traumatic brain injury. Sixteen adults will receive either real or sham stimulation while in the hospital. The main goal is to see if t…

This study will use transcranial Doppler (TCD) ultrasound to measure blood flow in the brains of 100 people who had a stroke and underwent endovascular therapy (clot removal). The goal is to see if TCD readings can predict complications like bleeding or brain swelling in the days…
