Description

Chen et al reported the Child-Na Score for predicting survival for a patient with cirrhosis who has had a TIPS procedure. The authors are from Fourth Military Medical University in Xi'an, China.


Patient selection: cirrhosis with symptomatic portal hypertension and variceal bleeding treated with TIPS

 

Parameters:

(1) Child-Pugh-Turcotte score, from 5 to 15

(2) points for serum sodium in mmol/L

where:

• Hypernatremia is not considered.

 

Child-Na score =

= (Child-Pugh score) + (3 * (points for sodium classification))

 

Interpretation:

• minimum score: 8

• maximum score: 24
