  2. Pathophysiology
    1. Cranial trauma results in subdural Hemorrhage
    2. Tear of veins between dura and surface of the brain
  3. Precautions: Acute Subdural Hematoma
    1. Acute subdurals are vastly different than chronic subdurals
    2. Acute subdural has a 60-80% mortality rate
    3. Requires rapid assessment and management (surgical decompression)
  4. Causes: Acute Subdural Hematoma
    1. Severe Closed Head Injury
    2. Rapid Deceleration Injury
  5. Associated Conditions: Acute Subdural Hematoma
    1. Comorbid Brain Contusion
  6. Symptoms
    1. Acute (Rapid progression of symptoms)
      1. Headache
      2. Irritability
    2. Chronic (Insidious symptom progression)
      1. Intermittent Headache
      2. Variable levels of Decreased Level of Consciousness
  7. Signs
    1. Acute
      1. Fluctuating levels of consciousness
      2. Dilated pupils
      3. Hemiplegia
      4. Hyperreflexia
      5. Babinski's Sign
      6. Convulsions
    2. Chronic
      1. Progressively impaired intellect
      2. Agitation
      3. Impulsive behavior
      4. Hemiparesis
      5. Stupor
      6. Variable Level of Consciousness
  8. Labs: Cerebrospinal fluid
    1. Increased CSF Opening Pressure
    2. CSF Protein increased
    3. CSF Bloody or xanthochromic fluid
  9. Diagnostic Testing: EEG
    1. Localized disturbance
  10. Management
    1. Surgical decompression
      1. Emergency surgical decompression if acute subdural

Hematoma, Subdural (C0018946)

Definition (NCI) Cerebral hemorrhage into the subdural space. See also Stroke Syndrome.
Definition (NCI) Cerebral hemorrhage into the subdural space. See also Stroke Syndrome.
Definition (MSH) Accumulation of blood in the SUBDURAL SPACE between the DURA MATER and the arachnoidal layer of the MENINGES. This condition primarily occurs over the surface of a CEREBRAL HEMISPHERE, but may develop in the spinal canal (HEMATOMA, SUBDURAL, SPINAL). Subdural hematoma can be classified as the acute or the chronic form, with immediate or delayed symptom onset, respectively. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.
