Radiofrequency (RF) ablation has been gaining popularity as a minimally invasive treatment for benign thyroid nodules regardless of the extent of the solid component. RF ablation of benign nodules demonstrated efficient volume reductions, while solving nodule-related clinical problems.

In brief, RF ablation uses the heat generated from high-frequency alternating electric current oscillating between 200 and 1200 kHz . The RF waves passing through the electrode agitate tissue ions around the electrode, and they increase the temperature (by frictional heat) within the tumor tissue, thus resulting in the destruction of tumor located very close, that is, within a few millimeters, to the electrode. In addition to the frictional heat, conduction heat from the ablated area can result in relatively slower damage of the tumor or to tissue remote from the electrode tip. This process of thermal injury secondary to friction and conduction heat is the basic mechanism of RF ablation.

Uterine fibroid embolization (UFE) is a procedure done by a radiologist. It blocks blood flow to fibroids in the uterus. (It is also called uterine artery embolization.) For women who are not planning a pregnancy in the future, UFE is a possible option in place of surgery for fibroids.

Follow your doctor's instructions exactly about when to stop eating and drinking, or your procedure may be canceled. If your doctor has instructed you to take your medicines on the day of your procedure, do so using only a sip of water. About an hour before the procedure, you may be given asedative to help you relax. It will not put you to sleep, because it is important that you be awake to follow instructions during the procedure.
