Radiofrequency Ablation (RFA) |

|
What is radiofrequency ablation?
Radiofrequency ablation (RFA) involves the localized application of heat to destroy tumor cells. RFA uses radiofrequency energy, a form of electrical current that can be used safely in the body. The radiofrequency energy is supplied by a generator that is attached to a device called a needle electrode.
Will I have an evaluation before the procedure?
You will have a clinical evaluation by an interventional radiologist. Diagnostic imaging will be done prior to the evaluation to confirm the location of the tumor. The evaluation will also include a brief physical examination.
Who does the RFA procedure?
An interventional radiologist (physician with special training in minimally-invasive procedures using image guidance) will perform the procedure.
How is the RFA procedure done?
The procedure can be done in a variety of ways. RFA can be performed percutaneously - through the skin. In this technique, the electrode is inserted through a small puncture in the skin. During each procedure, the interventional radiologist will use ultrasound or CT scanning to guide the needle electrode. This is to ensure that the electrode is in proper position in the tumor. The interventional radiologist will discuss the best approach for your particular case.
How long does the procedure take?
The duration of the procedure is dependent upon many factors, including the number of tumors to be treated, their location, and the approach that is used. Typically, a percutaneous procedure takes 1 to 1 1/2 hours.
Will I be asleep for the procedure?
You will be given general anesthesia for the procedure. The interventional radiologist will discuss this with you and answer any questions you may have.
How long will I have to stay in the hospital?
This will depend on how the procedure is performed. Your hospitalization could be as short as an overnight stay. Again, be sure to discuss this with the interventional radiologist.
What do I do after the procedure?
The interventional radiologist will give you specific instructions when you are discharged from the hospital. You will also be scheduled for follow-up visits so your physician can monitor your progress with blood tests and imaging techniques, such as x-rays, CT or MRI scans. The interventional radiologist will work closely with your physician to ensure you receive the best possible care.
