Background We report a rare case of 10-month-old female who underwent living donor liver transplantation (LDLT) for syndromic biliary atresia with preduodenal portal vein (PV) and its severe stricture owing to the previous Kasai portoenterostomy. Because we successfully performed "left at right liver transplantation (LAR-LT) and graft rerotation" in this case, we are present tips and pitfalls for this operation. Methods Preoperative computed tomography scan showed that her preduodenal PV was stenotic from the confluence of the superior mesenteric vein and splenic vein to hepatic hilum, which made us consider the necessity of ≥3 cm interposition vein graft to complete a safe PV anastomosis. To reduce a gap between donor and recipient's PV, we decided to put a left lateral section graft at the right subphrenic space called left-at-right liver transplantation. Thus, LDLT was performed with an identical lateral sectional graft from her father. After total hepatectomy, we implanted a graft in her right subphrenic space, and anastomosed the donor left hepatic vein to her inferior vena cava. Then, we anastomosed an interposition graft harvested from her left internal carotid vein to her PV. Results Even after reflowing PV flow, because the duodenum compressed the interposition vein graft, PV flows were totally insufficient. Therefore, we flipped a liver graft 180° from right to left upper abdominal cavity, which could reduce the gap between PVs and acceptable PV flow was obtained. Conclusions In the present case, LAR-LT could reduce the distance of PVs. In addition, our rerotation method could be useful to alleviate tension on the PV anastomosis caused by preduodenal PV.
