近年来,肝脏肿瘤的诊疗水平已得到很大提高,外科手术仍被认为是目前首选的治疗方法,但部分病人就诊时已失去手术指征。由于超声仪器及技术的不断改进,使超声引导下的微创介入疗法在肝脏肿瘤治疗上成为可能,并可部分达到临床治愈的效果,其中射频(Radio-frequency, RF)消融是近年治疗肝脏肿瘤的热点之一。本文就肝癌RF消融治疗的原理、方法、疗效及预后等进行综述。 1 肝癌RF消融的原理 RF消融的原理是通过电极针在人体组织中发射频率
In recent years, the diagnosis and treatment of liver tumors have been greatly improved. Surgery is still considered the first choice of treatment. However, some patients have lost the indication of surgery at the time of their visit. Due to the continuous improvement of ultrasound instruments and techniques, it is possible to use ultrasound-guided minimally invasive interventional therapy in the treatment of liver tumors, which can partially achieve the clinical effect of cure. Radio-frequency (RF) ablation is the treatment of liver tumors in recent years. One of the hot spots. This article reviews the principle, method, efficacy and prognosis of RF ablation for liver cancer. 1 The principle of RF ablation of liver cancer The principle of RF ablation is through the electrode needle firing frequency in human tissues
