Jason DAVIES presents the EMBOLISE Study, which examines the effectiveness of the Onyx™ liquid embolic system for embolization of the Middle Meningeal Artery (MMA) in treating subacute or chronic subdural hematoma. The study found that MMA embolization with Onyx™ significantly reduced the need for reoperation compared to surgery alone, without compromising neurologic function or safety. The treatment showed zero adverse events related to the Onyx™ device, and lower cSDH volumes at 90 days. These results suggest that MMA embolization with Onyx should be considered for patients with symptomatic subacute or chronic SDH requiring surgery.
