Image-guided percutaneous radiofrequency ablation (RFA) is a minimally invasive, relatively low-risk procedure for tumour treatment. Local recurrence and survival rates depend on the rate of complete ablation of the entire tumour including a sufficient margin of surrounding healthy tissue. Currently a variety of different RFA devices are available. The interventionalist must be able to predict the configuration and extent of the resulting ablation necrosis. Accurate planning and execution of RFA according to the size and geometry of the tumour is essential. In order to minimize complications, individualized treatment strategies may be necessary for tumours close to vital structures. This review examines the state-of-the art of different device technologies, approaches, and treatment strategies for percutaneous RFA of liver tumours.
影像引导经皮射频消融（RFA）是一种治疗肿瘤的微创、相对低风险的方法。局部复发率和生存率取决于整个肿瘤（包括周围健康组织的足够边缘）完全消融的速度。目前有多种不同的 RFA 设备可供选择。介入医生必须能够预测消融坏死的形态和范围。根据肿瘤的大小和几何形状进行准确的 RFA 规划和执行至关重要。为了最大限度地减少并发症，靠近重要结构的肿瘤可能需要个体化的治疗策略。本文综述了不同设备技术、方法和肝肿瘤经皮 RFA 治疗策略的最新进展。
