Middle Meningeal Artery Embolization and Nonacute Subdural Hematoma

Nonacute subdural hematoma is common among older persons. With an aging population and increasing use of antiplatelet and anticoagulant agents, subdural hematoma is projected to become the most common cranial neurosurgical disease by 2030.1 Standard treatments — including glucocorticoids and statins for milder cases, with the addition of surgery for more severe cases — are associated with a high risk of recurrence, which leads to repeat surgery in 15% of cases.2,3 Hematoma progression or recurrence is thought to arise from repeated hemorrhage from the outer vascularized hematoma membrane under the dura, which is supplied by the middle meningeal artery.
