There is limited data on upfront middle meningeal artery (MMA) embolization in the context of significant midline shift (MLS) (greater than 5mm) for the treatment of chronic subdural hematomas (cSDH). This study reports the temporal changes following MMA embolization as an upfront treatment of cSDH in patients with or without MLS and either mild, no symptoms or mild and stable neurological deficits. ⋯ Upfront MMA embolization for cSDH with a thickness up to 25 mm provides adequate symptom relief, stabilization and/or progressive resorption of the cSDH during follow-up in carefully selected asymptomatic or mildly symptomatic patients even in the presence of a MLS greater than 5 mm.
