Hepatectomía central combinada con ligadura de la vena porta derecha en un niño con hepatoblastoma bilobar: reporte de un caso

ABSTRACT Hepatoblastoma is a malignant tumor. Surgical resection is the goal of treatment. A 7-month-old female patient with a hepatic mass in segments IV A and B, V, and VIII, classified as PRETEXT III. A central hepatectomy preserving segments VI, VII, II, and III, and a double biliodigestive derivation were performed.  The right portal vein involved was ligated to produce a compensatory hyperplasia of the left liver, retaining the right one as an auxiliary. At 14 days, the left liver had increased by 48.1%. As an alternative to transplantation, central hepatectomy was combined with ligation of the right portal vein in a single surgical time.
