    Abstract:
    OBJECTIVE: Significance of portal hemodynamics for non-invasive marker of cirrhosis remains unclear. The aim was to determine the value of portal hemodynamics on Doppler ultrasound for predicting decompensation and prognosis in cirrhosis. METHODS: This retrospective study comprised 236 cirrhotic patients (132 males, 104 females; age 63.7 ± 11.3 years; 110 compensated, 126 decompensated). Clinical data, including Doppler findings, were analyzed with respect to decompensation and prognosis. The median follow-up period was 33.2 months (0.1-95.4). RESULTS: Fifty-three patients developed clinical decompensation, 13 patients received liver transplantation, and 71 died. Higher model for end-stage liver disease score (p < 0.001) at baseline was the significant factor for the presence of decompensation. Higher alanine transaminase (p = 0.020), lower albumin (p = 0.002) and lower mean velocity in the portal trunk (p = 0.038) were significant factors for developing decompensation (best cut-off value: Alanine transaminase > 31 IU/L, albumin < 3.6 g/dL, and portal trunk < 12.8 cm/s). The cumulative incidence of decompensation was higher in patients with portal trunk < 12.8 cm/s (22.5% at 1 year, 71.2% at 5 years) than those without (6.9% at 1 year, 35.4% at 5 years; p < 0.001). The significant prognostic factors were hepatocellular carcinoma (p = 0.036) and lower albumin (p = 0.008) for compensated patients, and reversed portal flow (p = 0.028), overt ascites (p < 0.001), and higher bilirubin (p < 0.001) for decompensated patients. CONCLUSION: Portal hemodynamics offer a non-invasive marker for decompensation and prognosis of cirrhosis, suggesting a future direction for practical management.
