Follow-up

Transfer

  • Detected subdural hematomas (SDHs) require patient transfer to facilities offering neurosurgical evaluation and treatment.
  • Transfer may be emergent, with appropriate stabilization measures taken and with appropriately skilled personnel accompanying the patient.

Complications

  • Postoperative complications
    • Elevated ICP
    • Brain edema
    • New or recurrent bleeding/hematoma
    • Infection
    • Seizures
  • Chronic SDH
    • Recurrent hematoma (50%)
    • Infection (eg, subdural empyema, wound)5
    • Seizures (up to 10%)

Prognosis

  • Definitive prognosis often is not possible at the time of emergency department evaluation.
  • Advanced age, presenting GCS less than 8, extension of blood into the intraventricular space, and uncontrolled ICP are factors associated with significantly reduced survivability.
  • Ultimate prognosis is related to the amount of associated direct brain damage and the damage resulting from the mass effect of the SDH.

Miscellaneous

Medicolegal Pitfalls

  • Failure to identify a patient with SDH and delayed diagnosis of the hematoma are constant risks.
  • Consider neuroimaging for patients taking anticoagulants.
  • Alcoholics may have an associated coagulopathy placing them at high risk for SDH. Altered mental status may be from an SDH, not ethanol.
  • Consult a neurosurgeon as soon as the diagnosis is suspected and initiate transfer if another facility is required for diagnosis or management.
