Cerebrospinal fluid volume associated with cerebral vasospasm post subarachnoid hemorrhage


  • This study sought to examine whether quantification of cerebrospinal fluid (CSF) or the aneurysmal subarachnoid hemorrhage (SAH)/CSF ratio would allow for better prediction of radiographic vasospasm (VS) versus blood volume alone.

  • Not only did the study confirm SAH volume and total blood volume as VS predictors, but suggest that CSF may be a valuable, and additional, VS clinical surrogate parameter.

Why this matters

  • This study provides evidence that CSF correlates with angiographic VS following aneurysmal SAH.

  • Quantification of CSF, together with SAH, could lead to improved patient risk stratification, and provide more accurate method of identifying those at risk over current traditional methods.
