Small-for-size syndrome is a clinical syndrome of early allograft dysfunction usually following living donor liver transplantation due to a mismatch between recipient metabolic and functional requirements and the graft's functional capacity. While graft size relative to the recipient size is the most commonly used parameter to predict risk, small-for-size syndrome is multifactorial and its development depends on a number of inter-dependant factors only some of which are modifiable. Intra-operative monitoring of portal haemodynamics and portal flow modulation is widely recommended though there is wide variation in clinical practice. Management of established small-for-size syndrome centres around meticulous patient care, infection prevention, fluid management and identifying correctable technical complications. However, retransplantation is the only treatment in severe cases. While small-for-size syndrome is associated with increased peri-operative mortality, the contribution of non-hepatic organ failure in determining patient outcomes needs further studies.
小体积综合征是一种早期移植肝功能障碍的临床综合征,通常发生在活体供肝肝移植后,原因是受者的代谢和功能需求与移植物的功能能力不匹配。虽然相对于受者体型的移植物大小是预测风险最常用的参数,但小体积综合征是多因素的,其发生取决于许多相互依存的因素,其中只有一些是可以改变的。尽管临床实践差异很大,但广泛推荐术中监测门静脉血流动力学和调节门静脉血流。已确诊的小体积综合征的管理围绕精心的患者护理、感染预防、液体管理以及识别可纠正的技术并发症展开。然而,在严重病例中,再次移植是唯一的治疗方法。虽然小体积综合征与围手术期死亡率增加有关,但非肝脏器官功能衰竭对患者预后的影响还需要进一步研究。
