Radiofrequency ablation in a pig liver model: effect of transcatheter arterial embolization on coagulation diameter and histologic characteristics.


To determine whether transcatheter arterial embolization (TAE) can alter radiofrequency (RF)-induced coagulation necrosis, we evaluated the morphology and histologic characteristics of RF ablation lesions combined with TAE in normal pig liver. Using a RF ablation system, consisting of a RF generator and 2-cm expandable LeVeen needle electrodes, nine lesions… (More)
