To summarize our experience using Computed Tomography Angiography (CTA) of the liver as an imaging tool for pre-living donor liver transplantation (LDLT) evaluation in biliary atresia (BA) patients. This pictorial review will illustrate and discuss several aspects of imaging techniques and the important findings that clinician need to know before LDLT.
Key imaging findings for vascular anatomy/collateral vessels will be made, emphasizing what clinicians need to know. Correlation with intraoperative findings will also be provided.

Liver transplantation is a potentially life-saving procedure for children with liver failure. Pediatric liver transplant recipients are at greater risk for complications such as vascular thrombosis than adults. In addition, children more commonly receive reduced size grafts, which alter the normal liver anatomy. While the postoperative assessment of pediatric liver transplants with sonography has been well studied, less exists in the radiology literature regarding intraoperative Doppler sonography of the graft prior to abdominal closure. We illustrate the intra- and post-operative ultrasound findings in pediatric liver transplants, with an emphasis on normal features, common pitfalls, and frequently encountered vascular complications.

In this education exhibit we will review a variety of presentations of posttransplant lymphoproliferative disorder (PTLD) and review the approach to imaging these patients. We will include cases that are atypical and discuss the pitfalls in imaging this population. We will provide imaging guidelines after a review of the current literature. Read More

In this exhibit we will describe a fairly new surgical procedure - total pancreatectomy and islet autotransplant (TPIAT). TPIAT is an uncommon procedure performed in children who suffer from chronic or recurrent acute pancreatitis. The purpose of the exhibit is to learn about the selection criteria, the surgery itself, and the imaging features of surgical complications.
Candidates are selected for surgery based on a multitude of factors including severity and chronicity of pain, laboratory evaluation of pancreatic exocrine and endocrine function, and imaging features of chronic pancreatitis on MRCP and/or endoscopic ultrasound.
In the surgical procedure, the pancreas and duodenum are resected, islet cells are isolated and then infused through the portal vein into the liver. A splenectomy is performed and continuity of the GI tract restored. Patients may spend three weeks in the hospital after surgery. Months after the infusion, the islet cells will be embedded within the liver and begin to produce insulin.
The primary goal of this procedure is to relieve debilitating pain and improve quality of life, for which this procedure is around 90% successful. The secondary goal of the procedure is to retain islet cell function. In this regard, approximately 40% of the pediatric patients will regain complete islet cell function, 30% will regain partial function while 30% will have no islet cell function.
Follow up imaging may also be performed on these patients for evaluation of complications such as delayed gastric emptying, small bowel obstruction, surgical site infections, bile leak, and intra-abdominal hemorrhage. Complications seen in our hospital, including small bowel obstruction, delayed gastric emptying, and prolonged ileus will be highlighted.

It is well known that ultrasound is a powerful imaging tool for pediatric patients after liver transplantation. With proper use, ultrasound provides static as well as dynamic information of the transplanted liver. The purpose of this educational exhibit is to demonstrate the way of good ultrasound examination after pediatric liver transplantation. Read More
