The influence of liver residual mass on the values of Acoustic Radiation Force Impulse Elastography (ARFI) in cirrhotic patients

Med Ultrason. 2011 Sep;13(3):195-9.

Abstract

Aim: The aim of our study was to assess the influence of liver residual mass in cirrhotic patients on the liver stiffness (LS), measured by ARFI elastography.

Methods: Two hundreds eleven cirrhotic patients were enrolled. To evaluate the liver residual mass, the Child-Pugh and MELD scores were used and 10 valid ARFI measurements were performed. The correlation between Child-Pugh, MELD scores and the LS were evaluated.

Results: Valid ARFI measurements were not obtained in 3 patients. A direct, very low correlation between the LS values and the Child-Pugh (r=0.264, p<0.001) and MELD scores (r=0.194, p=0.005) was found. A direct, low correlation between LS measurements and total bilirubin (r=0.271, p<0.001) and an inverse, low correlation with albumin (r=-0.270, p<0.001), prothrombin time (r=-0.196, p=0.006), cholinesterase (r=-0.241, p=0.003) was obtained. The LS mean values were statistically significant higher in patients with Child-Pugh class B vs. A (p=0.002) and in Child-Pugh C vs. A (p<0.001). The values were not significantly different in patients with Child-Pugh B vs. C (p=0.06).

Conclusions: Higher values of LS measurements by means of ARFI could be an indicator of decreased liver functional reserve, evaluated by means of Child Pugh or Meld scores.
