About this study

The study is a multi-center prospective, single-arm, post-market study evaluating the efficacy and radiologic and functional outcomes associated use of the Numen SILK coils for Middle Meningeal Artery (MMA) embolization following Chronic Subdural Hematoma (cSDH) compared to surgical evacuation or medical management alone. Chronic subdural hematoma is a collection of blood between the dural mater and the brain. It typically develops over time in older adults or people on anticoagulant medication. Blood slowly accumulates over time and often becomes encapsulated by a fibrous membrane over weeks or months, which can lead to the gradual development of symptoms. Middle Meningeal Artery embolization (MMAE) through coiling provides a minimally invasive option for cSDH treatment and prevention of reaccumulation and recurrence.
