🧠 Graeb IVH Score

UseWhen to use: spontaneous ICH with intraventricular extension on CT.

Loading calculator…

StrataHigher scores reflect greater IVH cast burden — correlate with hydrocephalus and exam.

LimitsWhen not to use: non-contrast CT unavailable. · Pitfall: missing expanded cast vs partial fill. · Not sole EVD decision.

When to use

When to use: spontaneous ICH with intraventricular extension on CT.

How it works

Lateral ventricles 0–4 each; 3rd and 4th 0–2 each; max 12.

Key points

  • Max 12.
  • IVH CT adjunct.
  • Next: ICH score / hydrocephalus.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Left lateral ventricle2 — <50% filled
Right lateral ventricle2 — <50% filled
Third ventricle1 — blood present
Fourth ventricle1 — blood present

→Graeb score6/12

  • Lateral L/R：2 / 2
  • 3rd / 4th：1 / 1
  • Cue：Moderate IVH burden

  • 3rd / 4th：0 / 0
  • Cue：Lower IVH burden

FAQ

Frequently asked questions

Does Graeb IVH Score upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Graeb IVH Score calculated in practice? Can you show a worked example?
Inputs: Left lateral ventricle 2 — <50% filled, Right lateral ventricle 2 — <50% filled, Third ventricle 1 — blood present, Fourth ventricle 1 — blood present → Result: Graeb score 6 /12（Lateral L/R: 2 / 2, 3rd / 4th: 1 / 1, Cue: Moderate IVH burden） Inputs: Left lateral ventricle 0 — none, Right lateral ventricle 0 — none, Third ventricle 0 — none, Fourth ventricle 0 — none → Result: Graeb score 0 /12（Lateral L/R: 0 / 0, 3rd / 4th: 0 / 0, Cue: Lower IVH burden）
