Comparison of clinical and radiological outcomes using solely particles versus particles with coils in middle meningeal artery embolization for chronic subdural hematoma: a longitudinal comparative cohort study

In the setting of cSDH, MMAe using particles only versus particles with coils shows similar rates of hematoma reaccumulation and resolution. Procedural time and fluoroscopy time were significantly reduced within the particle embolization-alone cohort. When comparing hematoma resolution and expansion, follow-up hematoma size > 1 cm, and decrease in hematoma size > 1 cm between groups, embolization using particles alone was not inferior to embolization using particles supplemented with coils.
