摘　　要：目的 探讨不含肝中静脉（middle hepatic vein,MHV）的成人间右半肝活体肝移植（living donor liver transplantation,LDLT）静脉流出道重建技术的改进方法.方法 通过长征医院器官移植研究所2007年6月至2008年1月完成的11例次成人间不含肝中静脉的右半肝活体肝移植病例的回顾性分析,对成人间不含肝中静脉的右半肝活体肝移植静脉流出道重建技术的改进进行总结.主要技术改进包括：采用供肝右肝静脉、受体腔静脉联合扩大成形吻合技术重建流出道;采用在4℃UW液中保存7 d以内的尸体同种异体静脉移植血管重建供肝Ⅴ、Ⅷ段肝静脉粗大属支以及右肝下静脉.结果 11例次成人间不含肝中静脉右半肝活体肝移植中10例次采用了右肝静脉、腔静脉联合扩大成形吻合技术;利用尸体同种异体静脉移植血管架桥重建肝Ⅴ、Ⅷ段肝静脉以及右肝下静脉流出道的例数占同期实施的成人间活体肝移植总例数的81.8%（9/11）,其中架桥重建1支肝静脉7例,架桥重建2支肝静脉1例,架桥重建3支肝静脉1例,11例病人中,1例病人术后14 d死于肾功能衰竭和肺部感染,超声检查血流通畅,未发现架桥静脉血栓,余10例病人术后随访9～15个月,右肝静脉均通畅,未发现静脉血栓,架桥肝静脉累计通畅率为：1个月100%（11/11）、3个月72.7%（8/11）、6个月54.5%（6/11）和9个月36.5%（4/11）,移植肝脏再生均衡,右肝端面Ⅴ或Ⅷ段无明显充血和肝萎缩坏死,肝功能正常.超声检查未发现血栓,血流通畅,移植肝脏再生均衡,右肝端面Ⅴ或Ⅷ段无明显充血和肝萎缩坏死,肝功能正常.结论 采用右肝静脉、腔静脉联合扩大成形吻合技术和在4℃UW液中保存7 d以内的尸体同种异体静脉移植血管重建肝Ⅴ、Ⅷ段肝静脉粗大属支以及右肝下静脉是一种简单、安全和有效的成人间不含肝中静脉右半肝活体肝移植肝静脉重建方法.Objective To investigate some improvements in the surgical techniques of adult-to-adult living donor liver transplantation（ A-A LDLT） without the middle hepatic vein（MHV） for hepat-ic vein reconstruction. Methods The retrospective analysis was made on the clinical data of 11 recipi-ents who underwent the operation in A-A LDLT including the hepatic vein reconstructed in right liver lobe without MHV from June 2007 to January 2008. The key techniques included reconstructing out-flow of graft on shaping the tips of vena cava and right hepatic veins, cadaveric vein allografts stored in 4℃ UW solution within 7d being used for significant-sized hepatic vein reconstruction such as tributa-ries of the middle hepatic vein from V5, V8 and right inferior hepatic vein. Results 10 cases success-fully underwent reconstruction of outflow of graft on shaping the tips of vena cava and right hepatic veins and the outflow reconstruction ratio of V5, V8 and right inferior hepatic vein was 81. 8% （9/11）, 7 one-vein reconstruction, 1 two-vein reconstruction and 1 three-vein reconstruction. 1 recipient died of renal failure and pulmonary infection 14 days after operation without venous outflow obstruc-tion. Doppler ultrasonography showed no thrombosis and the blood flowed smoothly in the right he-patic vein of other 8 recipients during the 9th to 15th mouth of follow-up. The cumulative patency rates of these 8 survivals for interposition vein grafts were 100% （11/11）, 72. 7 %（8/11）, 54. 5%（6/11） and 36. 5%（4/11） in 1, 3, 6 and 9 mouths, respectively. The regeneration of paramedian sectors was equivalent. Conclusion Shaping the tips of vena cava and right hepatic veins and using cadaveric vein allografts in adult-to-adult right lobe living donor liver transplantation for hepatic vein reconstruc-tion are both safe,simple and effective methods.This approach can be recommended.
