Vascular anomalies associated with biliary atresia in pretransplant survey.

BILIARY atresia is the most common indication for liver transplants in children, and this disorder is associated with some congenital vascular anomalies. Complex vascular anomalies increase the technical difficulties of the operation and previously resulted in high mortality in these patients. The role of the radiologist is to define the conditions in which transplantation is high risk or contraindicated and to identify any anatomic variations that may alter the surgical approach. The purpose of this study is to define the congenital vascular abnormal conditions in biliary atresia patients that would alter the surgical procedure during transplantation.
