Liver transplantation is currently the only curative treatment for patients with end-stage liver disease. However, liver transplantation can be associated with catastrophic complications in the early postoperative setting, including hepatic artery thrombosis (HAT) and portal vein thrombosis (PVT). Postoperative complications are associated with hepatic artery resistive index (RI) < 6, systolic acceleration time (SAT) > 0.08 seconds and peak systolic velocity (PSV) > 200 cm/s on doppler ultrasound (DUS). DUS is also used in an intraoperative setting to assess patency and early complications prior to the end of the operative period, allowing for early correction. This literature review evaluates the prevalence of DUS use in intraoperative settings to identify transplant complications. A lack of consistency and minimal knowledge of intraoperative DUS warrants additional research into its usage and standardization.
肝移植是目前终末期肝病患者唯一的治愈性治疗方法。然而，肝移植在术后早期可能会出现灾难性并发症，包括肝动脉血栓形成（HAT）和门静脉血栓形成（PVT）。术后并发症与多普勒超声（DUS）检查时肝动脉阻力指数（RI）<6、收缩期加速时间（SAT）>0.08秒和收缩期峰值流速（PSV）>200厘米/秒有关。DUS还用于术中评估手术结束前的通畅情况和早期并发症，以便进行早期纠正。这篇文献综述评估了术中使用DUS以识别移植并发症的普遍性。术中DUS缺乏一致性且了解甚少，因此有必要对其使用和标准化进行更多研究。
