This study is looking at a treatment called Middle Meningeal Artery (MMA) embolization using the TRUFILL n-BCA liquid embolic system for people with chronic migraine that hasn't responded to other treatments (refractory chronic migraine). The treatment involves blocking certain blood vessels in the head. Researchers want to see how safe and effective this treatment is. To join, you need to be between 18 and 65 years old, have been diagnosed with migraine before age 50, and have chronic migraine that started before age 64. The main goal is to see if the number of migraine days you experience changes after the treatment. The study is currently unclear about its recruitment status.
