Evaluation of short- and medium-term efficacy and complications of ultrasound-guided ablation for small liver cancer

Figure 1 Survival function of the two groups of patients. A: Progression-free survival function; B: Survival function. MWA: Microwave ablation.

Figure 2 A 75-year-old woman was diagnosed with a right hepatic lobe tumor on preoperative examination. A: The size of the right hepatic lobe tumor before microwave ablation, with relatively clear boundaries; B: The puncture and ablation process during microwave ablation, indicating that the needle insertion position was relatively accurate; C: The examination after microwave ablation. It can be seen that there is no enhancement in the venous and arterial phases, and the ablation range is 41 cm × 36 cm; D: The reexamination with contrast-enhanced ultrasound 3 mo after ablation, with no enhancement in arterial and venous phases.
