Portal Vein Velocity in Liver Cirrhosis across Child-Pugh Category: A Comparative Analysis

Abstract

Objective: Determine Child-Pugh category frequency in cirrhotic patients and compare mean portal vein flow velocity across categories A, B, and C.
Material and Methods: This cross-sectional survey study was conducted in the Department of Diagnostic
Radiology, Services Hospital, Lahore, and the duration of this study was from June 16, 2021, to December 16,
2021. Seventy cirrhotic patients were enrolled. Child-Pugh category, history, exams, and investigations were
performed. Portal vein velocity was measured by Ultrasound Doppler. Data were analyzed using SPSS
version 25, applying one-way ANOVA with p-value ≤0.05 considered significant.
Results: Seventy cirrhotic patients (49 males, 21 females) with mean age 40.66±16.61 years and mean BMI 227.15±8.14 kg/m were included. Class-C comprised 42.9%, while Class-A and B were 32.9% and 24.3%,
respectively. Significant differences in mean portal vein flow velocity were observed across Child-Pugh categories (p<0.05).
Conclusion: Portal vein peak velocity decreases with worsening Child-Pugh category, with reversed flow in Class C cirrhosis.
