Conversion therapy of hepatic artery ligation combined with transcatheter arterial chemoembolization for treating liver cancer: A case report

Figure 1 Pre-operative enhanced computed tomography scan of the upper abdomen. A large mass in the right lobe of the liver, centered on the right posterior lobe, with the larger section measuring about 14 cm × 10 cm × 14 cm. The right hepatic vein mostly ran along the edge of the lesion, and the right hepatic vein and right portal vein were affected by pressure.

Figure 2 At 53 d after the initial operation. No significant changes in patient’s left or right liver.

Figure 3 At 93 d after the initial operation. A large soft tissue mass in the right lobe of the liver, with dot-like or sheet-like high-density shadows, slightly smaller than previously. Other imaging findings were similar to before.

Figure 4 At 2 mo after the initial operation. A small amount of fluid in the operation area and no obvious abnormalities.

Figure 5 Hepatic angiography before and after intervention. A: The right hepatic artery was ligated, and the right liver tumor was mainly supplied by the middle hepatic artery and to a lesser extent by the left hepatic artery via the collateral circulation; B: The tumor-supplying branches of the middle and left hepatic arteries were embolized.
