Postsubarachnoid Shunt Score (PS3) for Permanent Shunt Insertion After Aneurysmal Subarachnoid Hemorrhage

Description

Motiei-Langroudi et al identified patients with aneurysmal subarachnoid hemorrhage who required permanent diversion of CSF to prevent hydrocephalus. The authors are from Beth Israel Deaconess Medical Center, University of Alabama, INOVA Health Systems, Seattle Science Foundation and Tabriz University in Iran.

Patient selection: aneurysmal subarachnoid hemorrhage

Parameters:

(1) external ventricular drain (EVD) insertion

(2) Hunt and Hess grade

(3) modified Fisher CT grade

Parameter	Finding	Points
EVD insertion	no	0
	yes	2
Hunt & Hess grade	1 to 3	0
	>= 4	1
modified Fisher CT	1 to 3	0
	4	1

where:

• A modified Fisher score 4 is thick SAH with intraventricular hemorrhage.

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 4

Score	Shunt Placement
0	11%
1	20%
2	48%
3	78%
4	100%
