Ogilvy and Carter grading

Q: Ogilvy and Carter grading system is used for which disease?

Answer: Subarachnoid Hemorrhage (SAH)

Ogilvy and Carter's grading for SAH is to predict outcomes for surgical management of SAH due to ruptured aneurysm. It is graded from 0 to 5 points, with one point each for following component:
  • age>50
  • Hunt and Hess grade 4-5 
  • Fisher grade score 3-4
  • aneurysm size>10 mm
  • additional point for a giant posterior circulation aneurysm (≥25 mm)

Study is validated, showing following outcomes.

Grade 0-2 = 78% good outcomes
Grade 3 = 67% good outcomes
Grade 4 = 25%  good outcomes
Grade 5 = not a surgical candidate
