Radiofrequency ablation
(Redirected from Fulgurate)
Radiofrequency Ablation[edit | edit source]
Introduction[edit | edit source]
Radiofrequency Ablation (RFA) is a minimally invasive medical procedure used to destroy abnormal tissue using heat generated from medium frequency alternating current. It is commonly used in the treatment of cancer, cardiac arrhythmias, and chronic pain, offering an alternative to invasive surgery for patients.
Mechanism[edit | edit source]
RFA works by inserting an electrode through the skin into the target tissue. Once in place, an electrical current is passed through the electrode, creating high-frequency radio waves that heat the tissue around the electrode's tip. This heat destroys the abnormal tissue without significant damage to surrounding areas.
Applications[edit | edit source]
- Cancer Treatment: RFA is frequently used to treat tumors in the liver, kidney, lung, and other organs.
- Cardiac Arrhythmias: It is used to correct heart rhythm problems by destroying tissue that causes abnormal electrical signals.
- Pain Management: RFA can target nerves that are causing chronic pain, providing long-term relief.
Procedure[edit | edit source]
The procedure is typically performed under local anesthesia, sometimes with sedation. It involves: 1. Imaging guidance (ultrasound, CT scan) to position the electrode accurately. 2. Insertion of the electrode into the target tissue. 3. Application of radiofrequency energy to heat and destroy the tissue. 4. Removal of the electrode and application of a bandage over the insertion site.
Benefits[edit | edit source]
- Minimally invasive with a relatively low risk of complications.
- Short recovery time compared to traditional surgery.
- Can be performed on an outpatient basis in many cases.
Risks[edit | edit source]
While RFA is generally safe, it carries potential risks, including:
- Infection at the insertion site.
- Damage to surrounding tissues or organs.
- Bleeding or hematoma formation.
