What is RFA Procedure ?
Radiofrequency ablation, or RFA, is a minimally invasive technique that shrinks the size of tumors, nodules or other growths in the body. RFA is used to treat a range of conditions, including benign and malignant tumors, chronic venous insufficiency in the legs, as well as chronic back and neck pain.
The procedure is similar to a needle biopsy, and involves inserting a needle-like probe into the body. Radiofrequency waves are sent out from the probe into the surrounding tissue, which causes the nearby cells to die. As these cells die, the immune system removes them, which causes an internal reaction and generally results in shrinkage of the nodule.
To place the tip of the probe in the correct location, the health care provider uses ultrasound or other imaging technique.
Radiofrequency ablation can take place in an office or outpatient setting and requires no general anesthesia. You may get medicine to help you relax for the procedure, as well as a numbing agent for the area of the skin where the probe is inserted. Most people undergoing radiofrequency ablation can go home the same day as their treatment and can return to their normal activities within 24 hours.
