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.

Fig. 3.

Subsequent right hepatic vein embolization following right portal vein embolization. (A) The right hepatic vein was visualized through transjugular approach. (B) The right hepatic vein was occluded with multiple coils and a vascular plug (arrow).

Fig. 4.

Computed tomography images following right portal and hepatic vein embolizations. (A) There were little hemi-liver volume changes 2 weeks after hepatic vein embolization. (B) A slight further atrophy of the right liver was found 2 months after hepatic vein embolization.

Fig. 5.

Computed tomography images before and after right hepatectomy. (A) Marked atrophy of the right liver was found at the 15 months after hepatic vein embolization. (B) CT taken 1 week after surgery showed prominent regeneration of the remnant left liver.

Fig. 6.

Gross finding of the resected right liver specimen. The hepatocellular carcinoma was nearly completely necrotic due to repeated chemoembolization, with background cirrhosis of mixed micro-and macro-nodular type.
