Risk of recurrence of subdural hematoma after EMMA vs surgical drainage - Systematic review and meta-analysis.

Objective: Chronic subdural hematoma (CSDH) is a common and debilitating neurological condition whose treatments, including burr hole drainage and craniotomy, suffer from high rates of recurrence and complication. Embolization of the middle meningeal artery (EMMA) is a promising minimally invasive approach to manage CSDH in a broad set of patients.

Methods: To evaluate the efficacy and safety of EMMA, a database search was conducted including the terms "subdural hematoma; embolization; embolized; middle meningeal" was performed and yielded a total of 260 results.
