Various scales have been devised for the prediction of vasospasm following aneurysmal rupture.
Especially prominent in these scales is their reliance upon a subjective assessment of clot thickness which introduces variability in grading across raters.
The current study seeks to compare the inter-rater reliability of the traditional Fisher and newer "Frontera" scale (Modified Fisher) when a rigid definition of thick clot is employed.
