The technique for thermal ablation in the lung by using radiofrequency ablation was first described in 1995 for use in animal lung tumor models and then in 2000 in humans. [1-2] Microwave ablation has emerged as a newer ablation modality and an addition to the arsenal of minimally invasive cancer care.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Therefore, IRE has none of the typical short and long term side-effects associated with necrosis. [31] [32] Short treatment time - A typical treatment takes less than 5 minutes. This does not include the possibly complicated electrode placement which might require the use of many electrode and re-position of the electrodes during the procedure.
These typically take the form of three types of ablative therapy: microwave thermal ablation, radiofrequency ablation ("coblation") and cryoablation. [49] Microwave thermal ablation. Microwave ablation is a treatment that uses heat to treat tumors. An interventional radiologist makes a tiny incision in the skin to insert a special needle into ...
By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring. [7]
These devices (brand names include Vivace and Morpheus8) puncture the skin with tiny insulated needles that deliver radio frequency energy to the dermis layer of the skin, stimulating collagen ...
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
During the procedure, which lasts about an hour, suction-like paddles are placed on the area being treated. Popular areas including the stomach, flanks and under the chin.
