Acute Epidural Hematoma - Surgical Decision (BTF Guidelines)

Acute Epidural Hematoma - Surgical Decision (BTF Guidelines): Acute Epidural Hematoma (EDH) Identified → EDH Volume >30 cm³? → SURGICAL EVACUATION → GCS...

Pathway Overview

14 steps

Algorithm Steps

14 total

  1. 01Start

    Acute Epidural Hematoma (EDH) Identified

    CT showing biconvex extra-axial collection, typically temporal/parietal location

  2. 02Decision

    EDH Volume >30 cm³?

    Measure hematoma volume on CT (ABC/2 method)

    • Volume = (A × B × C) / 2
    • A = largest diameter on axial CT
    • B = perpendicular diameter
    • C = number of slices × slice thickness
  3. 03Action

    SURGICAL EVACUATION

    EDH >30cm³ requires surgery regardless of GCS (BTF Level II)

    • Craniotomy preferred over burr hole
    • Allows complete hematoma evacuation
    • Identify and control bleeding source
    • Consider middle meningeal artery ligation
  4. 04Decision

    GCS <9 with Anisocoria?

    Comatose patient with pupillary asymmetry

    • Anisocoria suggests uncal herniation
    • Time-critical emergency
    • May have lucid interval history
  5. 05Warning

    ⚠️ EMERGENT SURGERY - AS SOON AS POSSIBLE

    Comatose + anisocoria = impending herniation (BTF Level III)

    • Do NOT delay for additional imaging
    • Operating room immediately
    • Consider mannitol/hypertonic saline en route
    • Alert anesthesia and OR staff
  6. 06Action

    SURGICAL EVACUATION

    Significant mass effect requires surgery

    • Thickness >15mm = significant compression
    • MLS >5mm = risk of herniation
    • Proceed to craniotomy
  7. 07Decision

    Thickness >15mm OR Midline Shift >5mm?

    Measure maximum thickness and midline shift on CT

  8. Path rejoins step 06Shared downstream outcome
  9. 08Decision

    GCS >8 AND No Focal Deficit?

    Assess neurological status

    • GCS must be >8 (not comatose)
    • No pupillary abnormalities
    • No motor deficits
    • Alert and oriented preferred
  10. 09Action

    NON-OPERATIVE MANAGEMENT

    Small EDH meeting all criteria (BTF Level III)

    • EDH <30cm³
    • Thickness <15mm
    • MLS <5mm
    • GCS >8
    • No focal neurological deficit
  11. 10Action

    Serial CT and Neuro Monitoring

    Close observation in neurosurgical center

    • Repeat CT at 6-8 hours
    • Neurological checks q1h
    • ICU admission preferred
    • Low threshold for repeat imaging if change
  12. 11Decision

    Clinical Deterioration OR CT Progression?

    GCS drop ≥2, new focal deficit, or hematoma expansion

  13. 12Action

    PROCEED TO SURGERY

    Failed non-operative management

  14. 13Outcome

    Continue Observation → Resolution

    EDH resolves with conservative management

  15. 14Action

    SURGICAL EVACUATION

    Focal deficit or depressed consciousness requires surgery

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Does not address pediatric-specific thresholds
  • Posterior fossa EDH requires separate considerations
  • Volume estimation requires radiological expertise
  • Does not replace neurosurgical consultation
  • Anticoagulation status affects management
