Middle Meningeal Artery Embolization for Chronic Subdural Hematoma

Background

Middle meningeal artery (MMA) embolization has emerged as a promising treatment for chronic subdural hematoma (cSDH).

Objective

To determine the safety and efficacy of MMA embolization.

Methods

Consecutive patients who underwent MMA embolization for cSDH (primary treatment or recurrence after conventional surgery) at 15 centers were included. Clinical details and follow-up were collected prospectively. Primary clinical and radiographic outcomes were the proportion of patients requiring additional surgical treatment within 90 d after index treatment and proportion with > 50% cSDH thickness reduction on follow-up computed tomography imaging within 90 d. National Institute of Health Stroke Scale and modified Rankin Scale were also clinical outcomes.
