Schematic illustration of anatomical ablation. (a) One applicator is placed across the tumor-bearing 5th portal vein branch. The other applicators are placed peritumoral zone. (b) The ablation zone covers all the tumor-bearing portal vein territory with a sufficient safety margin. (c) Small satellite nodules or microvascular invasion are located along the portal vein branches that drain from the primary tumor. (d) Anatomical ablation might effectively remove both the primary tumor and those satellite nodules or microvascular invasion
