12 Feb 2024 • For chronic or subacute subdural hematoma, embolization of the middle meningeal artery reduced recurrence, as per findings from the EMBOLISE trial presented at the American Stroke Association’s International Stroke Conference 2024.

• The EMBOLISE clinical trial tested whether a subacute or chronic subdural hematoma is less likely to require additional surgery if, in addition to surgical drainage, a substance is injected to block, or embolize, one of the arteries supplying blood to the dura.
• Patients were randomly assigned to receive either surgery alone or surgery+ embolization to help reduce the progression or recurrence of subdural hematoma.
• The results showed a nearly 3-fold reduction in re-operation for patients treated with surgery plus embolization.
• Subsequent subdural hematoma within 90 days and need for surgical drainage occurred in 4.1% of patients who had surgery plus embolization and 11.3% of those who had surgery alone.
