What is Radiofrequency Volumetric Thermal Ablation?

Radiofrequency Volumetric Thermal Ablation (RFVTA) is a therapy utilizing electrical energy that has been safely used in many medical applications. At its most simple level, this electrical energy is used to create heat in the surrounding tissue and destroy diseased cells. The heat is generated in a specific location, at a specific temperature, for a specific period of time. When applied correctly, RFVTA results in the death of the diseased tissue.

How Does Radiofrequency Volumetric Thermal Ablation Work?

The procedure is done an outpatient basis. Once the patient is sedated, the fibroids are visualized using ultrasound, and the Handpiece, including the Electrode Array, is inserted through the skin and placed into the target tissue. The Electrode Array is then deployed from the end of the Handpiece. A specially designed energy generator that is connected to the Handpiece is then activated, and delivers radiofrequency (RF) energy to the probe.

The RF energy flows through the electrodes and creates heat in the tissue through ionic agitation and frictional heat. Once sufficient temperature has been reached, the heat kills the target tissue within only a few minutes. The heat is continuously monitored through the thermocouples in the electrodes and the generator automatically adjusts the power so that the temperature in the target tissue remains constant. The heat treats the tumor and leads to cell death. The dead cells are gradually replaced by fibrosis and scar tissue. The body will naturally reduce the size of the scar tissue and eliminate it.

RFVTA is a safe treatment method. Ask your physician about treatment options for symptomatic uterine fibroids and how RFVTA can be used to treat your fibroids.
