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
