NCT ID NCT04410146
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a procedure called middle meningeal artery embolization using a special gel (SQUID) to treat chronic subdural hematoma, a condition where blood collects between the brain and its outer covering. 319 adults with a large blood collection were randomly assigned to receive the procedure or standard care. The goal was to see if the procedure could reduce the need for repeat surgery and prevent complications like stroke or death within 180 days.
