Adjuvant percutaneous radiofrequency ablation of feeding artery of hepatocellular carcinoma before treatment

Figure 2 A 65-year-old man with cirrhosis and Child-Pugh class A liver function. An HCC lesion was diagnosed during regular US examination. A: CT showed a tumor with a size of 3.2 cm × 3.0 cm in the right liver lobe; B: US showed a tumor (arrow) of 4.3 cm × 3.3 cm 3 mo later; C: CDFI showed blood flow into and around the tumor with a velocity of 56.7 cm/s; D: CDFI-guided PAA at the area where the feeding artery entered the tumor (arrow), to block the tumor blood supply; E: After PAA, CDFI showed that the previous feeding artery disappeared and no flow signal within HCC; F: After PAA, RFA was performed in the rest of the tumor; G: Contrast-enhanced CT (1 mo after treatment) showed an ablated area covering the previous tumor, without enhancement; H: Contrast CT (6 mo after treatment) showed no enhancement of the ablated area. The patient has survived more than 10 mo without tumor.
