Radiofrequency Thermal Ablation for Uterine Fibroids: Long-term Clinical Outcomes and Reinterventions

Radiofrequency thermal ablation, also often referred to as RFA, is a technique used in many areas of medicine. It can be used for treating anything from large varicose veins in the leg, to cancers in the liver or the kidneys. Today, this technology is also being used to treat women with fibroids.

The Acessa procedure utilizes a technology called radiofrequency ablation (RFA), and treats each fibroid by applying energy through a small needle array. The surrounding normal uterine tissue is not damaged or otherwise affected. Over time, the treated fibroid tissue shrinks and may become completely reabsorbed by the body. Acessa is performed under general anesthesia, and only two very small (approximately ¼”) abdominal incisions are needed during the procedure – there is no cutting, suturing or removal of the uterus itself.

“Until recently, there have not been large medical studies looking at which women will benefit the most from the Acessa procedure, versus other more common treatments such as Uterine Fibroid Embolization, myomectomy, and hysterectomy”, says Dr. Harris at the Fibroid Treatment Center. Now a new medical study performed in Denmark and Norway has shown that certain women may benefit more with the Acessa procedure over others.

66 women underwent the Acessa procedure over a several year period. “What the study found was that women who have one fibroid, which is less than 180 cubic cm, or about 7cm in diameter, benefit the most from RFA. Those women who have multiple fibroids or larger fibroids tend to need additional treatments after the RFA procedure more frequently than with other procedures,” Dr. Harris says. “We hope that more women will seek uterus preserving options such as UFE, Acessa, and myomectomy in the future as we understand that hysterectomy isn’t the treatment of choice for many women.”
