The reconstruction of the vascular outflow tract of partial liver grafts has received considerable attention in the past, especially in the setting of right liver grafts with undrained segments. Hepatic venous outflow reconstruction is an important factor for successful living donor liver transplantation outcome. However, in presence of undrained anterior sector and presence of multiple short hepatic veins that drain substantial portions of liver, outflow reconstruction without backtable venoplasty may lead to severe graft congestion and subsequent graft dysfunction. Various backtable venoplasty techniques in presence of multiple hepatic veins that can be used in either right- or left-lobe liver transplantation are devised to ensure a single, wide outflow channel. In this overview, various techniques to overcome the hepatic venous variations of liver allograft and outflow reconstruction are discussed.
部分肝移植血管流出道的重建在过去受到了相当多的关注，特别是在存在未引流节段的右肝移植情况下。肝静脉流出道重建是活体肝移植成功的一个重要因素。然而，在存在未引流的前叶以及存在多条引流肝脏大部分区域的短肝静脉的情况下，不进行体外静脉成形术的流出道重建可能会导致严重的移植肝充血及随后的移植肝功能障碍。为确保有一个单一、宽阔的流出通道，设计了各种可用于右叶或左叶肝移植的多条肝静脉存在情况下的体外静脉成形术技术。在本综述中，讨论了克服同种异体肝移植肝静脉变异及流出道重建的各种技术。
