Middle Meningeal Artery Embolisation in Chronic Subdural Hematoma

This international multicenter study evaluates the efficacy and safety of middle meningeal artery embolization (MMAE) using PVA particles or liquid embolic agents as a perioperative treatment to prevent the recurrence of chronic subdural hematoma (cSDH). All participating patients across centers in the Czech Republic and Slovakia will receive the minimally invasive MMAE procedure within 7 days prior to or after surgical evacuation, with the primary goal of assessing hematoma recurrence rates and procedure-related complications over a 90-day follow-up period.
