cisterns

Method:

  1. Grade each of the 10 basal cisterns and fissures separately on a scale according to the amount of extravasated blood:
    1. No blood = 0
    2. Small amount = 1
    3. Moderately filled = 2
    4. Completely filled = 3
  2. Grade clots that expanded the original size of a cistern or fissure as 3
  3. Calculate total amount of subarachnoid blood [sum score] by adding the 10 scores;  range = 0-30
  4. Use average score for inadequately visualized cisterns or fissures
  5. Grade the amount of blood in the four ventricles
    1. No blood = 0
    2. Sedimentation in posterior part = 1
    3. Partly filled = 2
    4. Completely filled = 3
  6. Calculate total amount of intraventricular blood [sum score] by adding the 4 scores; range = 0-12

 

Utility of Hijdra Score:

In one study, Hijdra sum score and history of smoking was noted to be the strongest predictors of cerrebral vasospasm on angiography.  This score was noted to be superior to the modified Fisher score as a tool to predict vasospasm after SAH.

Combined history of smoking and HSS >23 had positive and negative predictive values of 37 and 88%, respectively, for prediction of cerebral vasospasm after aneurysmal hemorrhage.
