Successful transumbilical embolization of congenitally ruptured hepatoblastoma.

To avoid a high-risk operation on a moribund neonate with a ruptured hepatic tumor, transumbilical embolization of the bleeding tumor was attempted in a 2-day-old neonate. A 3F microferret catheter was advanced through the right umbilical artery. After identifying the left hepatic artery feeding the bleeding tumor, Gelfoam (Upjohn, Kalamazoo, MI) particles were injected. Bleeding was successfully controlled. The infant was able to tolerate enteral feeding when stable. Seventeen days after embolization, elective left hepatic lobectomy was performed. Histological examination showed a fetal epithelial type hepatoblastoma. The baby is 13 months old now and is receiving chemotherapy.
