RFA uses radiofrequency energy, a form of electrical current that can be used safely in the body. The energy is supplied by a generator which is attached to a device called a needle electrode. The needle electrode is inserted into a tumor. The physician is guided in the placement of the needle by images from a CT scanner. Once the needle is in place, it is opened allowing multiple tines to spread out. Then, the generator is turned on and the radiofrequency energy is passed from the tines of the electrode into the tumor. This causes local heating and death of the tumor tissue.

The patient will be sedated intravenously so the procedure is not painful.

Since the patient's body is only penetrated with the needle electrode, RFA is minimally invasive. Most patients will be able to return home the day of the procedure. Others will be observed overnight before returning home. Because the procedure is minimally invasive, the patient can begin, or continue with, chemotherapy. In addition, the needle can be placed in locations unavailable to surgery, so that many tumors can be destroyed which would otherwise be inoperable.

How long will the procedure take?

RFA typically takes 1 to 1 ½ hours; however, the duration of the procedure depends upon how many tumors are being treated and their location.

After the Procedure

The Radiologist will give you specific instructions when you are discharged. You will also be scheduled for follow-up visits so your doctor can monitor your progress with blood tests and imaging such as x-rays, CT scans, MRI, and/or Nuclear Medicine. studies.
