Study Overview: This research looks at a new way to treat chronic subdural hematomas (SDHs), which are blood clots under the brain's outer covering. Normally, surgery is done to remove these clots. However, some patients, especially older ones, face high risks with surgery and the clots often come back. This study explores adding endovascular embolization after surgery, a less invasive procedure where doctors block blood flow in the middle meningeal artery to reduce clot recurrence.

Key Details:

• The study is for patients aged 18-90 who have undergone surgery for SDHs.
• Participants will be randomly placed in two groups: one will have surgery only, and the other will have surgery plus embolization.
• The study aims to see if the combination treatment reduces hospital stays, recurrences, and surgeries.

Eligibility: To join, patients must be between 18 and 90 years old, need surgery for SDH, and be in relatively stable condition as per medical scales. Exclusions include pregnancy, severe trauma, serious kidney or liver problems, and certain bleeding disorders. Participants must be able to consent or have a legal representative available.
