Abstract

We present a case of a two-yr-old boy diagnosed with HBT with complete main PVTT. HBT was located in the bilateral lobe with PVTT involving the confluence of the SMV and the SpV. Cisplatin-based neoadjuvant chemotherapy was delivered; main tumor shrank and AFP levels decreased to below one hundredth. However, PVTT remained in the bilateral portal branches to the main trunk of PV. We describe the technical details of the portal venous tumor thrombectomy that was succeeded by a LDLT. The patient remained healthy 2.5 yr after LDLT, showing good patency of the PV with no evidence of recurrence of tumor.

Keywords: hepatoblastoma; liver transplantation; portal vein tumor thrombosis.
