Abstract:

Objective To explored the application of auxiliary liver transplantation in a end-stage liver cirrhosis patient with high MELD score. Methods The preoperative liver function rating，MELD score and physicalstatus of patients were tested. The recovery of liver function and the occurrence and treatment of complications wereobserved. Results The weight of the split left liver graft with middle hepatic vein was 410 g and the ratio of graft to recipient weight was 0.82%. The liver enzymes of the recipient were the highest on the day after operation（ALT 420 U/L，AST 1 788 U/L）. On postoperative 5th day，routine contrast-enhanced CT found liver graft hepatic arterythrombosis，and conservative treatment was performed for observation. Total bilirubin level rose to a maximum of 387 μmol/L on postoperative16th day，and slowly decreased to normal 2 months after the operation. Three months afterthe operation，enhanced CT clearly showed the recovery of hepatic artery blood flow in the transplanted liver. Thepatient was followed up for 6 months with normal liver function and no other complications. Conclusion Auxiliaryliver transplantation is feasible for a liver cirrhotic patient with high MELD score，and it could be considered in the patient with performance status grade 3. It should be maximized to prevent and  treat hepatic artery thrombosis during auxiliary left liver transplantation.

摘要：

目的 探讨辅助性肝移植在高终末期肝病评分（model for end-stage liver disease，MELD）肝硬化患者中的应用。方法 检测患者术前肝功能评级、MELD 评分、体能状态。观察受者术后肝功能恢复情况和并发症的发生及处理。结果 劈离的带肝中静脉的左半肝移植物重量为 410 g，移植物受体体重比为 0.82%。受者术后当天肝酶最高（丙氨酸转氨酶为 420 U/L，天冬氨酸转氨酶为 1 788 U/L）。术后第5 天常规行增强 CT 确诊移植肝肝动脉血栓形成，予以保守治疗和观察。总胆红素术后第 16 天升至最高（387 μmol/L），术后 2 个月缓慢降至正常。术后 3 个月增强 CT 清楚显示移植肝肝动脉血流恢复。受者随访 6 个月，肝功能正常，无其他并发症发生。结论 辅助性肝移植治疗高 MELD 评分肝硬化患者是可行的，体能状态 3 级的患者可以考虑辅助性肝移植。行辅助性左肝移植时需要尽量预防和积极治疗肝动脉血栓形成。
