Exploratory findings suggest that peritruncal hematoma volume improves outcome predictions in aneurysmal subarachnoid hemorrhage, indicating a need for further validation.
Peritruncal blood volume is independently associated with outcome after aSAH and may be a clinically relevant marker in aSAH. Incorporating peritruncal components into current supratentorially based grading systems may enhance their predictive utility. These exploratory findings warrant prospective multicenter validation, and there is currently work focused on an "extended Fisher" approach that integrates infratentorial compartments.
