Middle meningeal artery embolization with polyvinyl alcohol particles in a patient with ophthalmic artery origin from middle meningeal artery: Case report and technical note
This is a case report of an adult with chronic subdural hematoma (cSDH) who underwent endovascular treatment for middle meningeal artery (MMA) embolization. There was a prominent meningo-ophthalmic branch with an absence of an ophthalmic artery from the internal carotid artery. MMA embolization was performed utilizing particles with no complications and the resolution of the cSDH was within 4 months. This case report demonstrates that despite extreme variant anatomy, MMA embolization with particles is feasible, effective, and safe when appropriate techniques are used.
