**14. Subdural hematoma embolization**

Chronic subdural hematoma may be one of the most common neurological conditions requiring treatment in the future because of an aging population and the regular use of antiplatelet and anticoagulation medications. Chronic subdural hematoma has been managed with craniotomy and/or drainage both operatively and at the bedside. Embolization of the middle meningeal artery supply to the dura and subdural membranes as a renewed treatment of chronic subdural hematoma has been originally described by Japanese neurosurgeons almost 20 years ago [88]. The technique can be used as a rescue technique in patients who have undergone previous craniotomy as well as a primary treatment in patients with significant comorbidities. Particle embolization and liquid embolic agents have demonstrated excellent results in recent publications [89]. These encouraging results suggested the need for a large prospective randomized trial to investigate the true role of middle meningeal artery embolization as a stand-alone treatment for chronic subdural hematoma.
