Orthotopic liver transplant (OLT) is established as the definitive treatment of choice for end stage liver disease. Over the years, refined surgical techniques as well as advancements in organ preservation and immunosuppressive regimens have improved graft and patient survival rates. Imaging has also contributed to improved graft and patient survival. Ultrasound is the initial investigation of choice for evaluation of post-transplant anatomy and for identifying early complications. A thorough knowledge of surgical techniques and normal post-operative appearance of the OLT is needed to accurately identify and characterize graft complications. The objective of this article is to review the sonographic findings of normal liver transplant as well as post-operative complications. Indications and contraindications for OLT as well as different surgical techniques will also be briefly reviewed.
原位肝移植（OLT）已被确立为治疗终末期肝病的首选方法。多年来，精细的手术技术以及器官保存和免疫抑制方案的进步提高了移植物和患者的生存率。影像学也有助于提高移植物和患者的生存率。超声是评估移植后解剖结构和识别早期并发症的首选初始检查方法。为了准确识别和描述移植物并发症，需要充分了解手术技术和 OLT 的术后正常外观。本文的目的是复习正常肝移植的超声表现以及术后并发症。OLT 的适应证和禁忌证以及不同的手术技术也将简要回顾。
