Radiofrequency ablation
Radiofrequency Ablation
Radiofrequency ablation (pronunciation: /ˌreɪdioʊˈfriːkwənsi əˈbleɪʃən/) is a medical procedure that uses electrical energy and heat to destroy or damage abnormal cells, particularly in the treatment of cancer.
Etymology
The term 'radiofrequency' is derived from 'radio', from the Latin 'radius' meaning 'beam of light', and 'frequency', from the Latin 'frequentia' meaning 'crowd' or 'multitude'. 'Ablation' comes from the Latin 'ablatio', meaning 'removal'.
Procedure
Radiofrequency ablation is performed using a thin, flexible tube called a catheter. The catheter is guided into the body through a small incision, usually in the skin. The catheter delivers high-frequency electrical currents, which generate heat and destroy the targeted cells.
The procedure is typically performed under local anesthesia, and the patient may be sedated. The procedure usually takes between 30 minutes to 3 hours, depending on the size and location of the tissue being treated.
Uses
Radiofrequency ablation is used to treat a variety of medical conditions, including:
- Cancer: It is often used to treat small tumors in the liver, kidneys, and lungs that cannot be removed surgically.
- Cardiac arrhythmia: It can be used to treat certain types of irregular heart rhythms.
- Varicose veins: It can be used to treat varicose veins by causing them to collapse and seal shut.
- Pain management: It can be used to reduce chronic pain by destroying nerve tissue that is causing the pain.
Risks and Complications
As with any medical procedure, radiofrequency ablation carries some risks. These may include bleeding, infection, damage to surrounding tissues, and complications related to anesthesia.
