Subdural hematoma

A subdural hematoma is a dangerous disorder where blood builds up between the skull and the brain’s surface. This kind of bleeding, acute or persistent, typically occurs after a head injury.

Symptoms

A subdural hematoma cause the following symptoms:

  • A headache that doesn’t go away
  • Having a sick feeling
  • Confusion
  • Personality alterations, such as unusual aggression or swift mood swings
  • Feeling sleepy
  • A lapse of consciousness

Subdural hematoma causes

A subdural hematoma occurs when an injury occurs in the brain’s blood vessel (the subdural space). When blood leaks from the blood vessel, a blood clot (hematoma) forms, putting pressure on the brain and harming it.

Subdural hematomas are frequently the result of severe head injuries, such as those suffered in a violent attack, fall, or vehicle accident.

However, mild head bumps can result in a subdural hemorrhage in a few instances.

If you are older than 60, taking blood-thinning medication, or have a history of alcohol abuse, a mild head injury is more likely to result in a subdural hemorrhage.

How to treat subdural hematomas

The most effective course of treatment for subdural hematoma is typically surgery.

The two most popular surgical procedures for treating:

    Subdural hematoma causes
    • In craniotomy, the surgeon temporarily removes a portion of the skull to access and remove the bleeding
    • Burr holes are small holes drilled, placing a tube into the head to help drain the hemorrhage

    You must consider minor subdural hemorrhages to see if they go away without surgery.
