Learning objectives To describe the indications, technique and complications of endovascular treatment by embolisation of the middle meningeal artery in chronic subdural haematomas and showing the technical and evolutionary details of our first cases.
Read more Background A bibliographic review of the endovascular treatment of chronic subdural haematomas is carried out, focusing on their physiopathogenesis, the procedure and the results reported in the latest experimental studies published as well as those of our own centre. To this end, we analyse the 28 cases of embolisation of the middle meningeal artery that have been carried out in our institution since March 2023 to date, both for prophylactic purposes as an adjuvant to surgery and for curative purposes. 
Read more Findings and procedure details 1. EpidemiologyChronic subdural haematoma is an abnormal collection of blood products in the subdural space. Its overall incidence is 1.72 - 20.6 / 100000 persons / year. There has been an increase in its incidence due to longer life expectancy, increased use of antiplatelet drugs and/or anticoagulants. It is more frequent in males (3:1), mainly due to the higher rates of alcoholism and epilepsy associated with this sex. In 20% of cases it is bilateral. 2. ClinicIt usually has an indolent course....
Read more Conclusion Embolisation of the middle meningeal artery as an aetiological treatment for chronic subdural haematomas, both for curative purposes and as an adjuvant to surgery. Promising results with a success rate of up to 98%, with low rates of recurrence and surgical salvage, as well as associated complications, in selected patients, making it an effective, reproducible and safe procedure.
