Intraventricular Hemorrhage Grade - Medical Algorithm

Graeb et al developed a score for grading the severity of intraventricular hemorrhage (IVH) following aneurysmal rupture, trauma or stroke.

Parameters:

(1) left lateral ventricle

(2) right lateral ventricle

(3) third ventricle

(4) fourth ventricle

Parameter	Finding	Points
left lateral ventricle	no blood	0
	trace or mild bleeding	1
	less than half of ventricle filled	2
	more than half of ventricle filled	3
	ventricle filled and expanded	4
right lateral ventricle	no bleeding	0
	trace or mild bleeding	1
	less than half of ventricle filled	2
	more than half of ventricle filled	3
	ventricle filled and expanded	4
third ventricle	no blood	0
	blood present, ventricular size normal	1
	ventricle filled and expanded	2
fourth ventricle	no blood	0
	blood present, ventricular size normal	1
	ventricle filled and expanded	2

total score =

= SUM(points for all 4 parameters)

Interpretation:

• minimum score: 0

• maximum score: 12

• The higher the score the more severe the intraventricular hemorrhage.
