What Is Middle Meningeal Artery Embolization for Chronic Subdural Hematomas?

Middle meningeal artery embolization (MMA embolization) is a minimally invasive endovascular procedure used to treat chronic subdural hematomas, which are collections of blood that develop slowly on the surface of the brain, often after minor head trauma. Rather than removing the blood surgically, this treatment targets the source of ongoing bleeding by blocking the middle meningeal artery, which supplies the fragile vessels responsible for hematoma recurrence. By cutting off this blood supply, the hematoma can stabilize and gradually resolve over time.

When Is Middle Meningeal Artery Embolization Recommended?

MMA embolization is increasingly used as a primary or adjunctive treatment for chronic subdural hematomas, especially in patients at higher risk for surgery or recurrence. It may be recommended in the following situations:

  • Recurrent Chronic Subdural Hematomas: To prevent re-bleeding after prior surgical drainage.
  • Non-Surgical Candidates: Patients with medical conditions that increase surgical risk.
  • Mild to Moderate Symptoms: Such as headaches, confusion, balance issues, or cognitive changes.
  • Patients on Blood Thinners: Where traditional surgery carries a higher bleeding risk.
This innovative approach is offered at only the best neurology clinic in Southern California for advanced neurovascular care.

What to Expect During Middle Meningeal Artery Embolization

The procedure is performed in a specialized angiography suite under local anesthesia with light sedation. A small catheter is inserted through an artery in the wrist or groin and navigated to the middle meningeal artery using advanced imaging guidance. Tiny embolic particles or liquid agents are then delivered to block blood flow to the membranes feeding the hematoma. The procedure typically takes one to two hours, and most patients are observed overnight and discharged the next day with minimal downtime.
