Modified Graeb Score (IVH burden)
Modified Graeb Score (0-32): intraventricular-hemorrhage burden across eight compartments, each with an expansion modifier.

Example
- Right lateral ventricle
- 4
- Right lateral ventricle: expanded by clot
- Yes
- Left lateral ventricle
- 4
- Left lateral ventricle: expanded by clot
- Yes
- Third ventricle
- 4
- Third ventricle: expanded by clot
- Yes
- Fourth ventricle
- 4
- Fourth ventricle: expanded by clot
- Yes
- Right occipital horn
- 2
- Right occipital horn: expanded by clot
- Yes
The other 6 values
- Left occipital horn
- 2
- Left occipital horn: expanded by clot
- Yes
- Right temporal horn
- 2
- Right temporal horn: expanded by clot
- Yes
- Left temporal horn
- 2
- Left temporal horn: expanded by clot
- Yes
Result: Modified Graeb 32/32: intraventricular-hemorrhage burden; each one-point rise raises the odds of poor functional outcome by about 12%.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Compartments
- four large compartments (both lateral ventricles, third, fourth) score fill 0-4 plus +1 if expanded; four horns (occipital and temporal) score fill 0-2 plus +1 if expanded; total 0-32.
- Outcome
- the total correlates with IVH volume and each one-point rise raises the odds of poor functional outcome by about 12%; no fixed cutoff is published.
