Abstract：Hepatocellular carcinoma(HCC)is a highly aggressive malignancy with a propensity for intrahepatic metastasis via the portal vein system.Anatomical hepatectomy(AH),which involves the systematic resection of the tumor-bearing portal vein territory,has been proposed as a superior surgical approach to improve oncological outcomes.Modern advancements such as 3D reconstruction have enhanced the precision of this technique,allowing for more accurate resection of the tumor-bearing portal vein territory.This surgical technique is in strict adherence with the oncological and anatomical principles,enabling a more precise excision of tumor tissue while preserving a greater extent of healthy liver parenchyma.It is anticipated that this approach will evolve into a more refined and widely accepted modality,thereby offer an enhanced therapeutic alternative for patients afflicted with liver cancer.
