In this retrospective review, the authors evaluated the anatomic and imaging features of 140 reduced-size liver transplants in 120 boys and girls; 100 of these patients (83.3%) were 2 years old or younger. The authors reviewed the surgical reports, plain radiographs, contrast material-enhanced studies of the gastrointestinal tract, duplex Doppler and color Doppler ultrasound (US) scans, and computed tomographic (CT) scans. Understanding the anatomic features associated with transplantation was crucial to understanding the postsurgical imaging characteristics. Changes in visceral anatomic structure caused a variety of imaging appearances, some of them misleading: (a) Some patients had unusual bowel gas patterns on plain radiographs because of a shift in location by bowel loops; (b) gastrointestinal studies showed gastric compression by an oversized left lobe that mimicked mass effect; and (c) displacement or migration of the duodenum, jejunum, or cecum into the right hepatic fossa sometimes mimicked malrotation. Pitfalls were created by fluid and gas collections at the transected edge. US and CT were often used to further assess anatomic structures after surgery; color Doppler was especially helpful in vascular localization.
