Comparison between bipolar pulsed radiofrequency and monopolar pulsed radiofrequency in chronic lumbosacral radicular pain
BACKGROUND Chronic lumbosacral radicular pain is a challenging medical problem with respect to therapeutic management. Many patients with lumbosacral radicular pain complain of persistent leg pain after transforaminal epidural steroid injection. Nowadays, pulsed radiofrequency (PRF) stimulation on the dorsal root ganglion (DRG) is widely used for controlling lumbosacral radicular pain. METHOD...
متن کاملNo-Touch Radiofrequency Ablation: A Comparison of Switching Bipolar and Switching Monopolar Ablation in Ex Vivo Bovine Liver
OBJECTIVE To evaluate the feasibility, efficiency, and safety of no-touch switching bipolar (SB) and switching monopolar (SM) radiofrequency ablation (RFA) using ex vivo bovine livers. MATERIALS AND METHODS A pork loin cube was inserted as a tumor mimicker in the bovine liver block; RFA was performed using the no-touch technique in the SM (group A1; 10 minutes, n = 10, group A2; 15 minutes, n...
متن کاملMorphological Changes Induced by Bipolar Radiofrequency Ablation in Thyroid Nodules – a Preclinical Ex Vivo Investigation
I ntroduction: Recently, radiofrequency ablation (RFA) has been increasingly used for the treatment of thyroid nodules. However, immediate morphological changes associated with bipolar devices are poorly shown. Aims: To present the results of analysis of gross and microscopic alterations in human thyroid tissue induced by RFA delivered through the application of the original patented device. Ma...
متن کاملFluid-modulated bipolar radiofrequency ablation: an ex-vivo evaluation study.
BACKGROUND The effect of radiofrequency ablation (RFA) can be modulated by fluid injection. PURPOSE To evaluate the potential of different fluids to modulate the effect of bipolar RFA in an ex-vivo liver model. MATERIAL AND METHODS A bipolar RFA system with an internally cooled needle-shaped applicator (20-mm active tip) was used to induce coagulation lesions in ex-vivo porcine liver. Prior...
متن کاملBipolar radiofrequency ablation of the kidney: comparison with monopolar radiofrequency ablation.
PURPOSE We report initial ex vivo and in vivo studies using bipolar radiofrequency (RF) ablation of porcine kidneys. An internal ground electrode is positioned in the kidney opposite the RF electrode, resulting in ablation of all the intervening renal tissue. MATERIALS AND METHODS Ex vivo preparations of 10 porcine kidneys were perfused continuously with Ringer's solution and treated with eit...
