VasoGrade simplifies the interaction between clinical severity and radiographic burden to stratify DCI risk into actionable tiers.
DCI Probability Probe
Input the WFNS and Fisher grades to determine the VasoGrade and associated risk of delayed cerebral ischemia (DCI).

When to Use
Day 1 risk stratification for patients admitted with an aneurysmal subarachnoid hemorrhage (aSAH).
Dictating the intensity of Transcranial Doppler (TCD) surveillance for vasospasm.

Development
Derived and validated by de Oliveira Manoel et al. (2015). Prior researchers noted that clinical status (WFNS) and radiographic blood thickness (Modified Fisher) are independent predictors of Delayed Cerebral Ischemia (DCI). VASOGRADE brilliantly synthesizes both into a simple stop-light scheme (Green, Yellow, Red) for neuro-ICU triaging.

Pearls/Pitfalls
Red vs Green
Vasograde-Red patients have a severe initial bleed causing poor clinical grade (WFNS 4/5) and massive thick SAH clot burden. Their risk of vasospasm is incredibly high. By contrast, Vasograde-Green patients have practically no risk and can often reliably avoid invasive angiography procedures if TCDs remain stable.
