ABSTRACT
AIM:
To assess the diagnostic accuracy of liver and spleen stiffness measured by 2-D shear-wave elastography (SWE) in evaluation of clinically significant and severe portal hypertension (CSPH and SPH, respectively).METHODS:
Clinical data of 155 hepatitis B-related cirrhosis patients and their liver and spleen stiffness (L-SWE and S-SWE, respectively) were collected. The diagnostic performances of L-SWE, S-SWE, the liver stiffness-spleen diameter to platelet ratio score (LSPS) and portal hypertension risk score were evaluated.RESULTS:
One hundred and four patients were eligible for analysis. Clinically significant and severe PH were detected in 84 and 74 patients, respectively. Liver and spleen stiffness were significantly correlated with hepatic venous pressure gradient in overall, CSPH, and SPH groups (rL = 0.607, 0.554, and 0.412; rS = 0.665, 0.566, and 0.467, respectively; all P < 0.05). The area under the receiver operating characteristic curves of L-SWE, S-SWE, LSPS, and PH risk score were 0.72 (95% confidence interval [CI], 0.49-0.95), 0.81 (95% CI, 0.55-0.97), 0.76 (95% CI, 0.51-0.96), and 0.73 (95% CI, 0.55-0.88) for CSPH, and 0.77 (95% CI, 0.51-0.93), 0.85 (95% CI, 0.59-0.96), 0.80 (95% CI, 0.58-0.98), and 0.80 (95% CI, 0.59-0.93) for SPH. The best cut-off of L-SWE for determining CSPH and SPH were 16.1 kPa (sensitivity, 78%; specificity, 72%) and 23.5 kPa (sensitivity, 81%; specificity, 79%). For S-SWE, the best cut-offs were 25.3 kPa (sensitivity, 85%; specificity, 79%) and 33.4 kPa (sensitivity, 74%; specificity, 70%). A cut-off of L-SWE <13.2 kPa or S-SWE <23.2 kPa was able to rule out CSPH, whereas a cut-off of L-SWE >24.9 kPa or S-SWE >34.2 kPa was able to rule in CSPH.CONCLUSIONS:
Liver and spleen stiffness measured by 2-D SWE are reliable and promising non-invasive parameters to assess CSPH and SPH.
