Portal Hypertension, Spleen Disease, Cirrhosis
Conditions
Brief summary
Portal hypertension is a major complication of cirrhosis. HVPG is the diagnostic gold standard but is invasive. Non-invasive tools such as spleen stiffness measurement (SSM) and CEUS show promise for assessing CSPH, though they have not yet been compared directly. A multimodal ultrasound approach may provide a reliable alternative to HVPG.

Eligibility
Inclusion criteria
Individuals of both sexes aged 18 years or over; Subjects diagnosed with liver cirrhosis. Subjects who have undergone hepatic venous pressure gradient (HVPG) measurement to assess portal hypertension, and/or show indirect clinical signs of significant portal hypertension, such as oesophageal varices or porto-systemic collateral circulation. Cirrhotic subjects who must undergo contrast-enhanced ultrasound as part of regular hepatological follow-up. Subjects who have given their informed consent.
Exclusion criteria
Subjects aged under 18 years; Subjects with cholestatic disease Subjects diagnosed with clinically significant portal hypertension of non-cirrhotic aetiology. Subjects diagnosed with ascites Subjects diagnosed with splanchnic thrombosis Subjects presenting with spleno-portal flow reversal Subjects who are allergic to ultrasound contrast media Subjects who have not given their informed consent.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Primary endpoint | 12 months | evaluate the diagnostic performance between the selected parameters and the gold standard for assessing portal hypertension, i.e., HVPG using the ROC curve and calculation of sensitivity, specificity, VPP, VPN, and AUC. Bland-Altman analysis will be applied to assess concordance. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Secondary endpoint | 12 months | The determination of the ideal cut-off point |
