Abstract:
Stereotactically guided radiofrequency thermoablation (RFTA) for epilepsy has been frequently applied over the last 40 years. Radiofrequency electrodes with temperature control function generate a coagulation lesion with clearly defined borders. In combination with high-resolution MRI imaging, this technique allows minimally-invasive ablation of periventricular nodular heterotopias, small focal type II dysplasias, and hypothalamic hamartomas. This review summarises the literature addressing this topic mainly regarding technical aspects. In essence, RFTA is a safe treatment option for patients suffering from epileptogenic pathologies visible on MRI-images.
