Summary

This trial investigates whether a procedure called middle meningeal artery embolization can reduce the recurrence of chronic subdural hematoma—a collection of blood on the brain's surface that often comes back after standard treatment. The study enrolls adults with a hematoma at least 10 mm thick who also have at least one risk factor for recurrence, such as older age or use of blood thinners. Participants receive either the embolization procedure within a week of randomization or standard care, and researchers track how often the hematoma returns.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a procedure called middle meningeal artery embolization, which blocks blood flow to the outer lining of the brain to prevent re-bleeding
What this could lead to
If it works, this could offer a way to lower the chance that a chronic subdural hematoma comes back after initial treatment, reducing the need for repeat surgery.
What could go wrong
This is a relatively new application of an existing technique, and it is being tested in a specific high-risk group, so results may not apply to all patients. The procedure itself carries small risks like bleeding or stroke.
