RATIONALE

Chronic subdural hematoma (CSDH) is a common neurological affliction which affects mostly frail and elderly patients.

Surgical evacuation by using burr hole craniostomy (BHC) is the most frequently used treatment but carries a recurrence rate varying between 10-30% in the literature. Especially in this frail population re-operation is undesirable.

Embolization of the middle meningeal artery is an adjuvant treatment which has been reported in multiple case reports and larger case series, showing a beneficial effect on recurrence rate, reducing it to <5%, without complications.
