Liver and Soft Tissue Ablation

What is Radiofrequency Ablation?

Radiofrequency ablation (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 which is attached to a device called a needle electrode.

First, the needle electrode is positioned within the lesion and opened, allowing the multiple tines to spread out.

Then, the generator is turned on and radiofrequency energy is passed from the tines of the electrode into the lesion. The energy creates heat that destroys the cells in the area. The result is destruction (ablation) of the liver lesion. After a period of time, the liver absorbs the destroyed cells.

How is the RFA procedure done?

The procedure can be done by different methods. RFA can be performed percutaneously, which means “through the skin.” In this technique, a needle electrode, such as Boston Scientific’s LeVeen® Electrode is inserted through a small puncture in the abdominal wall. RFA can also be done using a minimally invasive surgical technique called laparoscopy. For laparoscopic RFA, tiny incisions are made in the abdominal wall. A small camera called a laparoscope is inserted through one incision. The surgeon uses the camera to guide placement of the LeVeen Needle Electrode as it is inserted through another incision. Finally, RFA can be performed through an open abdominal incision (laparotomy) during surgery.

During each of these procedures, your doctor will use ultrasound or CT scanning when inserting the needle electrode. This is to help ensure that the electrode is in proper position in the lesion.

Your doctor will discuss the best approach for your particular case.
