Many therapeutic options have been reported to date. Embolization of middle meningeal artery is an interesting option for refractory chronic subdural hematoma. Multi-institutional studies with pooling of patients are necessary to generate evidence-based treatment guidelines. © 2011 Lippincott Williams & Wilkins, Inc.
