Evaluating outcomes of middle meningeal artery embolization for chronic subdural hematoma
Official title: Outcomes of Middle Meningeal Artery for Treatment of Chronic Subdural Hematoma; Middle Meningeal Artery Embolization for Chronic Subdural Hematoma (MESH)
Run by Montefiore Medical Center · NCT06181994 · Data updated 2026-11-12
This study tests if a new, less invasive treatment called middle meningeal artery embolization can safely help adults with chronic subdural hematoma and reduce the chances of it coming back.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adult patients aged 18 years or older who have undergone endovascular embolization of the middle meningeal artery.
✕Probably not a fit
Patients who have received endovascular embolization using materials other than those specified in the study will not benefit from this research.

What this trial studies
This observational study investigates the real-world outcomes of chronic subdural hematoma (cSDH) treated with middle meningeal artery embolization (MMAE). It focuses on assessing clinical effectiveness, recurrence rates, and the safety profile of this minimally invasive treatment approach. The study involves a multi-center retrospective cohort design, analyzing data from adult patients who underwent MMAE. The goal is to determine whether this technique offers a favorable alternative to traditional surgical methods.
Why it matters
Potential benefit: If successful, this study could provide a safer and less invasive treatment option for patients with chronic subdural hematoma.
How similar studies have gone: While the approach of MMA embolization is relatively novel, preliminary studies have suggested promising outcomes, indicating potential for success.
