Management of Chronic Subdural Hematoma With Adjunctive Embolization of Middle Meningeal Artery

Does adjunctive embolization of the middle meningeal artery (EMMA) after surgical drainage reduce recurrence of chronic subdural hematoma compared with surgery alone?In this randomized clinical trial of 186 participants with unilateral symptomatic chronic subdural hematoma, adjunctive EMMA after surgery significantly reduced symptomatic recurrence detected on computed tomographic scan (4% vs 28%) at 90 days compared with surgery alone.Adjunctive EMMA performed after surgical drainage lowered chronic subdural hematoma recurrence, supporting its role as an effective addition to surgical management of chronic subdural hematoma.
