The development of large spontaneous portosystemic shunts (PSS) is a common finding in liver cirrhosis. The diversion of the portal flow through PSS directly into the caval system causes progressive liver atrophy and atretic changes of the portal vein. During both living and deceased donor liver transplantation (LT), persistence of large PSS has been associated to portal flow steal phenomena causing decreased patients and graft survival. Atretic changes of the portal vein and large PSS often coexist potentially representing a technical challenge during portal vein reconstruction. We herein describe (with a didactical video) an easy augmentation patch V-venoplasty used in the presence of atretic changes of the portal vein LT.

大量自发性门体分流（PSS）的发生是肝硬化的常见现象。门静脉血流通过 PSS 直接进入腔静脉系统，导致进行性肝萎缩和门静脉闭锁变化。在活体和已故供体肝移植 (LT) 过程中，大量 PSS 的持续存在与门静脉血流盗流现象相关，导致患者和移植物存活率下降。门静脉闭锁变化和大 PSS 经常共存，这可能是门静脉重建过程中的技术挑战。我们在此描述（通过教学视频）一种简单的增强补片 V 形静脉成形术，用于存在门静脉 LT 闭锁变化的情况。
