Percutaneous Radiofrequency Ablation for Liver Tumors: Technical Tips

Yozo Sato, Takaaki Hasegawa, Shohei Chatani, Shinichi Murata, Yoshitaka Inaba

Abstract

Percutaneous radiofrequency ablation (RFA) has been accepted as a minimally invasive therapeutic treatment for liver malignancies. Although RFA is usually applied for the treatment of small liver tumors (<3 cm), several technical developments have expanded the use of RFA. RFA is now used for the treatment of large liver tumors, and the number of complications associated with this treatment has decreased. These refinements may ultimately lead to better long-term prognosis. Here, we review recent refinements of liver RFA and provide technical tips.
