Objective To summarize the clinical experience of segmental living related liver transplantation for very small infant with biliary atresia. Methods The recipient was a 145-day-old male with congenital biliary atresia. The infant was 66 cm in height and weighed 3.08 kg. The donor was his 36-year-old mother. Her segment Ⅱ of the liver was excised and orthotopically transplanted into the infant's body as the graft. The portal vein of the graft was end-to-end anastomosed to the portal vein of the recipient, the hepatic artery of the graft was end-to-end anastomosed to the proper hepatic artery of the recipient with lateral superficial vein of left great saphenous vein from donor as a bridge, and the hepatic vein was end-to-end anastomosed to the hepatic vein of the recipient whose hepatic vein was conformed from right, middle and left hepatic vein. Biliary tract was reconstructed via Roux-en-Y operation. Results Segment Ⅱ (160 g) of liver from donor was resected, and there was no blood infusion. The donor retained her liver function within 5 days and was discharged on the eighth day. The operating time of graft implantation was 451 min. The blood loss was 250 ml. Non-liver stage was 71 min. The cold ischemic time was 132 min. Cyclosporine, mycophenolate mofetil (MMF) and prednisone were used for postoperative immunosuppression. The bilirubin level of the infant was decreased to the normal level one week after operation, and the liver function became normal in 9 days. Jejuno-leakage on the 7th day after the transplantation was recovered by mend and drainage and discharged on the 35th day. The donor and recipient were in satisfactory condition to present. Conclusion The segmental living related liver transplantation is advisable for very small infant with biliary atresia. Perfect operative technique and postoperative intensive care are the keys to ensure the success of the procedure.

Objective To summarize the clinical experience of successful liver transplantation from infant donation after cardiac death (DCD) for infant with biliary astresia (BA).Methods The donor was a 16-months-old girl with a body weight of 10 kg,who died of irreversible anoxic cerebral damage after sudden asphyxiation.The recipient was a 24-months-old girl with a body weight of 12 kg,who suffered from icteric concurrent late biliary cirrhosis after the Porta-jejunum anastomosis because of congenital BA.The DCD liver was classically orthotopically transplanted into the infants recipient.The warm ischemia time was 7 min,the cold ischemia time was 360 min,and the graft volume to the standard liver volume (GV/SLV) was 1.02.After operation,the vital signs and transplanted liver function of the recipient were monitored,and the recipient was given treatments of anti-infection,anticoagulation,and improving the microcirculation.The recipient was treated with the triple immunosuppression protocol of tacrolimus,mycophenolate and prednisone to prevent rejection.Results The operating time of the recipient was 480 min,the non-liver stage was 65 min,and the blood loss was 230 mL.The endotracheal intubation was removed from the recipient at 12 h,and the recipient started to eat at 48 h aftcr operation.The recipient had a hepatic artery thrombus on the 3rd and 15th day after operation,and the hepatic artery had re-blood-supply after the hepatic artery catheterization and continuous perfusion with urokinase.The recipient was discharged on the 42nd day,and the recipient was in satisfactory condition to present.Conclusion The infant DCD liver is a better graft for infant liver transplantation for BA.The surgical complications can be reduced with matched volume of donor-recipient liver; and it can guarantee a successful operation with perfect operative technique and careful perioperative management.
