Noninferiority of coiling versus coiling with particles in middle meningeal artery embolization: A technical note and case series

All patients demonstrated symptomatic and radiographic improvement at three month follow-up. None of the patients in this cohort received surgical evacuation of the hematoma prior to or after embolization. One patient had previously been treated for hydrocephalus with a VP shunt. There were no postoperative complications. In the hematomas treated with a combination of coils and particles, three showed complete resolution with one showing interval improvement on imaging. All hematomas treated with coils alone demonstrated complete resolution after three months. Conclusions: Middle meningeal artery embolization with coils alone has demonstrated noninferior results to embolization with a combination of particle embolisate and coils in this small cohort.
