Brain clot breakthrough? new procedure may slash recurrence risk

This study looks at whether blocking a specific artery in the brain (middle meningeal artery) can lower the chance of a chronic subdural hematoma—a type of blood clot on the brain—coming back after standard surgical drainage. About 192 adults with a symptomatic clot larger than 10 mm will be randomly assigned to get either surgery alone or surgery plus the artery-blocking procedure. The main goal is to see if the clot returns within 90 days, with safety and recovery also tracked.
