Proximal Onyx embolization of the middle meningeal artery (POEM) technique for non-acute subdural hematomas: a single-center study of 123 patients using the Scepter dual-lumen balloon microcatheter

By minimizing the risk of reflux, balloon-assisted MMAe allows for safe embolization from a more proximal location. The POEM technique shows that proximal embolization with dual-lumen balloon microcatheters treats NASDH effectively, achieving substantial hematoma resolution with low recurrence. Prospective studies comparing POEM with other techniques are warranted to confirm its comparative efficacy.
