Description:
<jats:sec><jats:title>Objectives</jats:title><jats:p>This study was intended to establish normal values for velocities in the hepatic artery and portal veins in pediatric patients after total pancreatectomy and islet autotransplantation (TPIAT).</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A retrospective review was performed of liver Doppler studies in pediatric patients after TPIAT over 6 years at an academic children's hospital. Doppler velocities in the liver vasculature and the hepatic artery resistive index were recorded.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Sixty‐five pediatric patients were evaluated. There were no cases of portal vein thrombosis or other hepatic vascular complications. The mean hepatic artery peak systolic velocity was 157.6 cm/s (SE, 60.9 cm/s), with a mean resistive index of 0.57 (SE, 0.09). The mean main portal vein velocity was 31.9 cm/s (SE, 12.9 cm/s).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Portal vein thrombosis is rare in pediatric patients after TPIAT. A wide range of hepatic artery and portal vein velocities are encountered in children immediately after TPIAT without hepatic vascular complications and can be considered normal.</jats:p></jats:sec>
