Neonatal biliary atresia combined with preduodenal portal vein: A case report

Background Congenital biliary atresia is a type of obstruction of the bile ducts inside and outside the liver, which can lead to cholestatic liver cirrhosis and eventually liver failure. The preduodenal portal vein (PD-PV) is a rare developmental malformation of the PV. The PV courses in front of the duodenum. However, very few cases of neonatal biliary atresia combined with PD-PV have been reported in the scientific literature. Case summary A 1-mo-and-4-d-old child was admitted to the hospital in January because of yellowish skin. After surgical consultation, surgical intervention was recommended. The child underwent Hilar-jejunal anastomosis, duodenal rhomboid anastomosis, and abdominal drainage under general anesthesia. During the operation, the PV was located at the anterior edge of the duodenum. Conclusion Diagnoses: (1) Congenital biliary atresia; (2) PD-PV; and (3) Congenital cardiovascular malformations. Outcomes: Recommendation for liver transplantation. Lessons: The choice of treatment options for neonatal biliary atresia combined with PD-PV.
