![]() | Fig. 1.Initial application of transarterial chemoembolization. (A) Hepatic arteriogrphy shows a large-sized hypervascular mass at the right liver. (B) Two weeks after embolization, CT showed extensive tumor necrosis but incomplete lipiodol uptake, implica-ting presence of viable tumor cells. |
![]() | Fig. 2.Preoperative right portal vein embolization. (A) The portal vein system was visualized through percutaneous ipsilateral approach. (B) After occlusion of the right portal vein with multiple coils and gelfoam, only the left portal vein was visualized. |
