Endoscopic third ventriculostomy (ETV) success score

Endoscopic third ventriculostomy (ETV) success score

ETV success score = Age score + etiology score + previous shunt score

≈ Percentage probability of ETV success
Category Score
Age
  • <1 month = 0
  • 1 to <6 months = 10
  • 6 to <12 months = 30
  • 1 to <10 years = 40
  • ≥10 years = 50
Etiology
  • Postinfectious = 0
  • Myelomeningocele, intraventricular hemorrhage, or nontectal brain tumor = 20
  • Aqueductal stenosis, tectal tumor, or other etiology = 30
Previous shunt
  • Previous shunt = 0
  • No previous shunt = 10
Interpretation:
  • The score in each category (age, etiology, previous shunt) are added together to determine the total score.
  • The total score estimates the percent probability of ETV success.
    • ≥80 percent – High likelihood of success
    • 50 to 70 percent – Moderate likelihood of success
    • ≤40 percent – Low likelihood of success
