Abstract
Organ transplantation continues to grow in demand in the pediatric population. The liver is the second most common organ that is transplanted in the pediatric population, but it results in the greatest number of interventional procedures. Transplant continues to be the preferred treatment for end-stage liver failure in children and has been shown to prolong life. There are several significant differences in liver transplantation between adults and children. They include different indications and diseases leading to transplant, the smaller body size of children, and differences in the surgical techniques used to implant the liver. These differences have led to a set of complications that is unique to or is more frequently seen in the transplanted child. The complications require interventional solutions tailored to the special needs of children. This paper will examine the complications that are encountered and the technical challenges that the interventionalist must address to successfully treat this subgroup of children. The purpose of this paper is to present the techniques and "pearls" that we have found to be helpful in treating this group of patients that in many ways is the most challenging in all of pediatric intervention.
