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).
Radiofrequency thermocoagulation is a thermal pain treatment procedure. For example, percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) involves the placement of an electrode or catheter into the intervertebral disc and applying an alternating radiofrequency current.
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [ 5 ] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures.
Chemical ablation: one of the earliest ablative techniques involving the injection of substances such as ethanol or acetic acid into a tumour to cause protein denaturation and cell death. Radiofrequency ablation: tissue destruction through delivery of electricity that produces ionic friction.
Non surgical treatments include steroid injections in the lower back or radiofrequency sensory ablation. [6] Physical therapy interventions are also helpful in early cases and are focused around mobilization, neural stretching, and core strengthening exercises. Surgical intervention is usually a last resort if all conservative methods fail. [3]
The device uses radiofrequency or ultrasound to ablate the renal nerves. Typically, numerous ablations are applied at a different longitudinal and rotational positions to ensure maximal denervation. [13] The procedure does not involve a permanent implant. [citation needed]
Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves ...
In this procedure, a local anesthetic is injected directly into the respective joint, usually in combination with a cortisone preparation (corticosteroid). For long-term relief in more severe cases, Radio-frequency ablation or Rhyzotomy, where the anterior and posterior spinal nerve root is burnt may be performed. [11]
