Anatomical considerations in the imaging of 'reduced-size' liver transplantation in children

In liver transplantation, understanding the altered anatomical features unique to the reduced-size hepatic allografts commonly used in children is crucial in assessment of the post-surgical imaging findings. The radiologist needs to be aware of these findings because the reconstructed anatomy can lead to many imaging pitfalls if not adequately appreciated. This paper aims to evaluate the US and CT findings with regard to the anatomical features, the patency of relevant vasculature and the presence of the more commonly encountered complications in children with reduced-size liver transplants.
