Subdural hemorrhage - chronic; Subdural hematoma - chronic; Subdural hygroma
The goal is to control symptoms and minimize or prevent permanent damage to the brain.
Surgery may be required. This may include drilling small holes in the skull to relieve pressure and allow blood and fluids to be drained. Large hematomas or solid blood clots may need to be removed through a larger opening in the skull (craniotomy).
Hematomas that do not cause symptoms may not require treatment.
Chronic subdural hematomas that cause symptoms usually do not heal on their own over time. They often require surgery, especially when there are neurologic problems, seizures, or chronic headaches.
Some chronic subdural hematomas return after drainage, and a second surgery may be necessary.
Because of the risk of permanent brain damage, call a health care provider promptly if you or someone else develops symptoms of chronic subdural hematoma. For example, call if you see symptoms of confusion, weakness ,or numbness weeks or months after a head injury in an older person.
Take the person to the emergency room or call 911 if the person:
