Middle Meningeal Artery Embolization for Nonacute Subdural Hematoma

Among patients with symptomatic nonacute subdural hematoma (of whom 78% underwent burr-hole drainage), middle meningeal artery embolization resulted in a 90-day incidence of symptomatic recurrence or progression similar to that with usual care but was associated with a lower incidence of serious adverse events.
