Portal Vein Reconstruction in Children Undergoing Living Donor Liver Transplantation for Biliary Atresia

Key Points

• To investigate the etiology of portal vein narrowing following living donor liver transplantation in children with biliary atresia.
• Analyzed cases of children receiving living donor liver transplantation for biliary atresia.
• Assessments included evaluating portal vein narrowing and the need for replacement.
• Developed a model incorporating BMI and mPVA for predicting native portal vein usability for anastomosis.
• Significant portal vein narrowing was observed post-operation, necessitating reconstruction.
• The narrowing was unrelated to the cholestasis condition of biliary atresia.
• The predictive model successfully estimates the usability of the native portal vein.
