Subdural hemorrhage - chronic; Subdural hematoma - chronic

The goal is to control symptoms and minimize or prevent permanent damage to the brain. Corticosteroid medications may be used to reduce any swelling of the brain. Anticonvulsant medications, such as phenytoin, may be used to control or prevent seizures.

Surgery is often required. This may include drilling small holes in the skull to relieve pressure and allow blood to be drained. Large hematomas or solid blood clots may need to be removed through a larger opening in the skull (craniotomy).

Few chronic subdural hematomas heal themselves over time. They often require neurosurgery, particularly in the case of significant brain displacement, neurologic problems, seizures, or chronic headaches. Some chronic subdural hematomas return after drainage, and a second surgery may be necessary.

• Permanent brain damage
• Persistent symptoms
  • Loss of memory
  • Dizziness
  • Headache
  • Anxiety
  • Difficulty maintaining attention
• Seizures

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.

Take the person to the emergency room or call 911 if the person has convulsions/seizures, isn't responsive, or loses consciousness.
