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

Figure 1 The child underwent laparoscopic exploration under general anesthesia. During the operation, the portal vein was located at the anterior edge of the duodenum.

Figure 2 Intraoperative cholangiography showed that the intrahepatic bile duct was visualized by percutaneous puncture catheter-based injection of the contrast agent, but the biliary tract system was not clearly visualized, the duodenum was not visualized, and there was no contrast agent in the abdominal cavity.
