Introduction Chronic subdural hematoma (cSDH) is one of the most common neurosurgical diagnoses with a high recurrence rate in aging population. The primary pathologic process repeated micro bleeding from fragile neo‐vessels supplied by peripheral branches middle meningeal artery (MMA). MMA embolization an efficacious minimally invasive neuroendovascular technique for management chronic hematoma. It has demonstrated reduced incidence re‐bleeding and cSDH elderly patients. Particle liquid embolic materials are commonly used to devascularize however studies comparing safety outcomes between these two limited. Our objective was perform descriptive analysis investigate differences among frequently employed embolization. Methods We performed single center retrospective review patients ≥ 18 years who had July 2020 May 2022. safety, radiation dosage, fluoroscopy time, radiographic clinical were compared particle A continuous categorical variables using SAS 9.4 version.
