Surgery is typically performed once neurological symptoms develop. Recent studies suggest that arteries nourished by the middle meningeal artery (MMA) may be responsible for hematoma progression and that MMA embolization is clinically useful. There is less evidence, that embolization of MMA also may be a treatment option for individuals without surgical treatment. The investigators propose a multicentre study to investigate both potentials: (1) Assessment of efficacy of embolization after surgery to reduce recurrence and improve outcomes by conducting a randomized trial (randomization arms; Arms 1 and 2), (2) Assessment of embolization-alone efficacy when surgery is contraindicated or refused (embolization-only arm, Arms 3 and 4).",[90,91],"Chronic Subdural Hematomas","Cerebral Compression Due to Injury","2026-03-16",{"date":94,"type":95},"2026-03-17","ACTUAL",{"date":97,"type":95},"2025-02-18",{"date":99,"type":84},"2027-01-01",{"name":5,"class":6},2]
