Single site, prospective, comparative effectiveness pilot trial comparing efficacy and safety outcomes of three embolic materials (particles, liquid embolics, and Wallaby Phenox coils) in MMA embolication for cSDH.
Participants will be sequentially enrolled into one of three treatment arms based on the embolic material used during their MMA embolization: Cohort/Arm 1: Particles (polyvinyl alcohol or similar microspheres) Cohort/Arm 2: Liquid embolics (Onyx, n-BCA, or equivalent) Cohort/Arm 3: Phenox coils (Avenir UNO Helical Coil) Participants will remain on study through their standard 30- and 90-day follow-up visits. With a target of 30 patients (10 per arm), the study will provide preliminary data on radiographic efficacy (primary: hematoma resolution/thickness reduction), safety (complications, rec…
