Ultrasound-Guided Radiofrequency Ablation of Liver Tumors — Analysis of Immediate Outcomes at Gomel Regional Clinical Oncology Center

Abstract

Objective: to systematize the existing techniques of ultrasound-guided percutaneous radiofrequency ablation.Materials. The research subjects were 34 patients with focal liver malignancies who had undergone radiofrequency ablation at Gomel Regional Clinical Oncology Center from 2014 to 2019.Results. The data about the existing techniques of ultrasound-guided percutaneous radiofrequency ablation have been systematized. The possibilities to increase the ablation efficiency of the liver tumor foci have been determined. The main components of the treatment algorithm that allow to achieve the best ablation results have been identified.Conclusion. Strict adherence to the described techniques of radiofrequency ablation which takes into account tumor vascularisation makes it possible to achieve complete necrosis of the foci with no complications in 82.4 % of the patients, and minor complications that do not require therapy in 17.7 % of the patients [9].
