New study tests better way to drain brain bleeds after surgery
NCT ID NCT06621407
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of drainage after surgery for chronic subdural hematoma (a blood collection on the brain). 354 adults in Denmark will receive either active drainage under the scalp or passive drainage under the brain's outer layer for 24 hours. The goal is to see which method better prevents the hematoma from coming back and reduces death within 90 days.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
drainage procedure (active subperiosteal or passive subdural)
What this could lead to
If active drainage works better, it could lower the chance of the hematoma coming back and reduce deaths after surgery.
What could go wrong
This is a non-inferiority trial, so it may only show that active drainage is not worse than the standard method, not that it is better. Results are limited to a specific surgical technique and may not apply to all patients.
