Screening of hepatopulmonary syndrome (HPS) with CEUS and pulse-oximetry in liver cirrhosis patients eligible for liver transplant.

Abstract

From 186 patients diagnosed with liver cirrhosis, 56 patients (30.10%) had delayed LV enhancement of the contrast agent. Pulse-oximetry showed alterations, such as SaO2 95%and PaO2 70 mmHg in 62 patients (33.33%). Pearson index showed a good correlation between lung and heart CEUS findings and pulse-oximetry (r=0.99) in HPS diagnosis. CONCLUSIONS. Two non-invasive, simple and rapid methods such as CEUS and pulse-oximetry can easily diagnose HPS, a highly fatal complication of liver cirrhosis, and can also guide the future treatment by speeding up OLT recommendations.
