Subdural Haematoma
Medical Questions » Subdural Haematoma
| Name: Subdural Haematoma |
| Also known as: |
| A collection of blood between the brain and the skull that puts pressure on the brain and affects its function. The dura mater is the outermost of the three meninges (membranes) that surround and support the brain, so by definition this is a bleed between the dura mater and the arachnoid mater which is the middle membrane. The innermost membrane is the Pia mater. |
Causes of Subdural Haematoma
Usually due to a significant head injury, but sometimes due to the rupture of a blood vessel affected by arteriosclerosis, high blood pressure or for no obvious reason. Onset may be sudden, or may be delayed for some weeks after a head injury if the bleed and build up of pressure is very gradual. |
Symptoms of Subdural Haematoma
Confusion, vomiting, dizziness, headache and abnormal brain function (eg. partial paralysis, strange sensations) depending on the position of the blood collection and the pressure it applies to the brain. |
Tests for Subdural Haematoma
CT or MRI scan used to find blood collection. |
Treatment for Subdural Haematoma
Urgent surgical removal of blood collection.
|
Complications of Subdural Haematoma of its treatment
Permanent brain damage possible but uncommon. |
Likely Outcome of Subdural Haematoma
May be fatal or cause permanent disability if left untreated. Good results from surgical treatment. |
