1).

Additional intracerebral hemorrhage (ICH) was associated with an increased risk of delayed cerebral ischemia (DCI). Furthermore, adding the presence or absence of ICH to the modified Fisher Scale (mFS) improved the identification of patients at the highest risk for the development of DCI. Thus, a simple adjustment of the mFS might help to identify patients at high risk for DCI 2).


The mFS and the modified Graeb score (mGS) have similar prognostic utility. Accounting for IVH volume improved prediction of Delayed cerebral ischemia (DCI) by the mFS 3).
