Summary

Younger age and anisocoria predict better functional recovery after traumatic transtentorial herniation. Early assessment of brain stem function is crucial for determining outcomes in these critical patients.

Area of Science:

  • Neurosurgery
  • Neurology
  • Trauma Critical Care

Background:

  • Traumatic transtentorial herniation is a severe neurological emergency.
  • Predicting functional recovery is challenging but essential for patient management.

Purpose of the Study:

  • To identify factors associated with functional recovery after traumatic transtentorial herniation.
  • To determine the most significant predictors of outcome in these patients.

Main Methods:

  • Retrospective review of 153 patients with clinical signs of transtentorial herniation.
  • Analysis of demographic data, clinical findings (pupillary response, Glasgow Coma Score), and outcomes.

Main Results:

  • 18% of patients achieved functional recovery (good or moderate disability).

  • Younger age, pediatric status, anisocoria, and deteriorating Glasgow Coma Score (GCS) were associated with better outcomes.
  • Bilaterally fixed and dilated pupils at admission significantly predicted poor functional recovery.

    • Conclusions:

    • Age, initial level of consciousness, and brain stem function are key determinants of outcome.
    • Anisocoria is a more favorable prognostic indicator than fixed, dilated pupils.
    • Early identification of prognostic factors can guide clinical decision-making.
