An interventional radiologist is frequently called to evaluate and treat biliary diseases in children; a tailored approach specific to this population is required. Imaging with an emphasis on minimizing ionizing radiation is used not only in the initial workup but also to guide interventions. The most common form of intervention generally consists of transhepatic biliary drainage to treat either biliary obstruction or bile leakage, a scenario frequently encountered after pediatric liver transplantation. Other pathologies referred for evaluation and management include biliary atresia and, rarely, symptomatic choledochal cysts. Biliary complications caused by an underlying malignancy are not a frequently encountered problem in the pediatric population. The initial evaluation, role of preprocedural imaging, and interventional management with an emphasis on technique are discussed regarding these common biliary pathologies in children.
Keywords: biliary atresia; biliary interventions; cholangiogram; cholecystogram; liver transplantation.
