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.
