Kasai portoenterostomy (KPE) restores bile drainage and prolongs native liver survival (NLS), yet BA remains the leading cause of pediatric liver transplantation. Therefore, reliable predictors of KPE failure are needed. This study evaluated hepatic blood flow velocities (HBFV) via ultrasound as potential non-invasive predictors of NLS after KPE. We retrospectively analyzed 163 BA patients treated between 2008 and 2023 at two German tertiary centers. Standardized Doppler ultrasound measured HBFV before and 3 months after KPE. Hepatic artery velocities, resistive index (RI), and portal vein flow were correlated with liver function, cholestasis, and fibrosis grade (Ishak). Furthermore, we assessed their predictive value at 3-month follow-up for NLS at 6 and 24 months. NLS in the presented cohort was 63.58% at 6\u00a0months and 40% at 24\u00a0months follow-up. No significant associations were identified between HBFV and liver fibrosis grade or cholestasis parameters (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05).
