A 73-year-old man was diagnosed as having hepatitis C virus-related liver cirrhosis 11 years ago. Two years ago, he developed hepatocellular carcinoma in segment 6 of the right lobe and received radiofrequency ablation. This time, he was admitted to our hospital with a local recurrence in segment 6 of the liver. Standard sonography could not visualize the lesion clearly. However, carbon dioxide-enhanced sonogram clearly showed the whole lesion, so a needle electrode could be inserted precisely, allowing safe and accurate radiofrequency ablation. By combining radiofrequency ablation with transcatheter arterial chemoembolization, complete tumor necrosis was achieved without the need to perform additional ablation. In conclusion, carbon dioxide-enhanced sonographically guided radiofrequency ablation combined with transcatheter arterial chemoembolization is useful for complete cure of localized tumors, such as recurrent hepatocellular carcinoma, which cannot be detected clearly by conventional sonography.
一名73岁男性11年前被诊断为丙型肝炎病毒相关性肝硬化。两年前，他在右叶6段发生肝细胞癌并接受了射频消融治疗。此次，他因肝脏6段局部复发入住我院。标准超声检查无法清晰显示病变。然而，二氧化碳增强超声检查清楚地显示了整个病变，因此可以精确插入针电极，从而实现安全、准确的射频消融。通过将射频消融与经动脉化疗栓塞相结合，无需进行额外消融即可实现肿瘤完全坏死。总之，二氧化碳增强超声引导下的射频消融联合经动脉化疗栓塞对于传统超声检查无法清晰检测到的局限性肿瘤，如复发性肝细胞癌的完全治愈是有用的。
