在普通外科领域,Rossi[1]和McGahan[2]等 1990年首先报道利用射频消融 (radiofrequencyabla tion, RFA)致肝组织深部热损伤的实验研究, 提出不能手术切除的小肝癌有可能通过射频热损伤而毁损。1992年McGahan等又以猪肝进行射频灭活试验,使用单极射频针在B超引导下经皮穿刺消融,
In the field of general surgery, Rossi [1] and McGahan [2] et al. first reported in 1990 the use of radiofrequency ablation (RFA) to induce deep thermal injury in liver tissue, suggesting that small hepatocellular carcinoma that cannot be surgically resected is likely to pass radiofrequency heat. Damaged and damaged. In 1992, McGahan et al. again performed radiofrequency inactivation experiments with pig livers, and used a unipolar radiofrequency needle to perform percutaneous puncture ablation guided by ultrasound.
