[Diagnostic accuracy of liver and spleen stiffness by two dimensional shear wave elastography for portal hypertension in hepatitis B-related cirrhosis].
2020
Objective: To assess the diagnostic accuracy of liver and spleen stiffness measured by two dimensional shear wave elastography (2D-SWE) in hepatitis B-related cirrhosis. Methods: The clinical data of fifty-eight hepatitis B-related cirrhosis patients were collected in Zhongshan Hospital, Fudan University from September 2017 to April 2018. Pearson's correlation analyses were used to assess the relationship between liver/spleen stiffness (L-SWE and S-SWE) and hepatic venous pressure gradient (HVPG), as well as the comparison with serological model. The SWE diagnostic performances of Liver (L-SWE), Spleen (S-SWE) were also evaluated. Results: Of all 58 patients, 47 were found HVPG ≥10 mmHg, diagnosed as clinically significant portal hypertension (CSPH) and severe portal hypertension (SPH), which patients are at increased risk of developing complications. Thirty-four patients were found HVPG≥12 mmHg, diagnosed as SPH, which patients were at increased risk of variceal bleeding. Moderate positive correlation was found between L-SWE and HVPG (r=0.42, P 12.86 kPa or S-SWE was>35.73 kPa, patients were at increased risk of developing complications. The area under the receiver operating characteristic curves for SPH were 0.68, 0.81 and 0.77 and the S-SWE had the highest specificity, so when S-SWE was>41.5 kPa, patients were at increased risk of variceal bleeding. Conclusion: L-SWE and S-SWE are reliable and promising non-invasive parameters to assess CSPH and SPH.
