Introduction and ObjectivesLiver cirrhosis, a major global health issue, causes blood flow resistance and portal hypertension. This study uses Doppler ultrasound to correlate hemodynamic changes with MELD 3.0 scores and variceal hemorrhage. Portal vein velocity, hepatic artery velocity, and hepatic artery resistance index were retrospectively evaluated in 2023 patients.
Patients / Materials and MethodsData analysis was performed at the end of the study using GraphPad Prism version 10.2.3 and Microsoft Excel software. Individual correlation analysis was conducted between the hemodynamic variables and the MELD 3.0 score using Spearman's correlation coefficient. A Mann-Whitney test was performed to determine the association between HAV and variceal hemorrhage based on non-normal distribution data. The cut-off point was established with a ROC curve according to the Youden Value.
Results and DiscussionSeventy-nine cirrhotic patients (56% men, 54% women; mean age 58.8 years) had varied etiologies: 44 alcohol-related, 10 metabolic, and 25 other. Average MELD 3.0 score was 15 (range: 6-70). Fifteen patients had variceal hemorrhage within 6 months (mean 76.8 days; 6-178). HAV correlated significantly with hemorrhage (mean 188 cm/s vs. 66.0 cm/s; p = 0.0007), with a cut-off of 115 cm/s (88% sensitivity, 53% specificity). HAV moderately correlated with MELD 3.0 (r = 0.3942, p = 0.0003); HARI-MELD 3.0 showed a weak inverse correlation (r = -0.02190); PVV-MELD 3.0 had no significant correlation.
ConclusionsHAV correlates positively with the MELD 3.0 score and is positively associated with variceal hemorrhage in patients with liver cirrhosis. Given its non-invasive nature and greater accessibility compared to endoscopic studies, HAV could be considered a tool for screening variceal hemorrhage.
