[[Intraventricular hematoma]] score.

see also [[LeRoux score]].

Components

Each lateral ventricle

1 = trace of blood

2 = less than 50% filled

3 = more than 50% filled

4 = completely filled and expanded

3th and [[Fourth intraventricular hemorrhage]]s

0 = no blood

1 = blood present, size normal

2 = filled with blood and expanded

====Calculation====

Graeb score = righ ventricular score + left ventricular score + 3th ventricular score + 4th ventricular score

===== Retrospective case-control studies =====

A study suggests that elevated modified Graeb score on initial computed tomography and high cerebrospinal fluid protein levels prior to EVD wean are important prognostic indicators for the development of [[shunt dependency]] after aneurysmal SAH. Integrating these findings into clinical practice may aid in earlier and more targeted decision-making
