[Uterine artery embolization for the conservative management of leiomyoma]

Abstract

Uterine leiomyoma, a benign, monoclonal tumor derived from a single myometrial cell, is one of the most frequent diseases in the female reproductive system. However, the factors involved in its initiation and growth remain poorly understood. Most commonly, it results in dysmenorrhea, menorrhagia, urinary tract and neurological symptoms, and abdominal distension. Additionally, it may cause infertility, late miscarriage or other severe complications in pregnancy. The conventional treatment for fibroids has been hysterectomy. However, many women do not like to lose their uterus and potential fertility. Myomectomy and medical treatment with GnRH analogue are accepted as alternative organ-conserving methods with limited efficacy. Selective embolization of uterine arteries might therefore have a significant role in the management of the disease. The purpose of this study was to determine the effectiveness of uterine embolization as primary therapy in the management of myomas. Uterine arterial embolization was performed in 3 patients with symptomatic leiomyomas. The uterus and fibroids were objectively evaluated with ultrasound and MRI. The efficacy and safety convinced the authors that this promising technique is at present the only reasonable alternative method in organ-conserving therapy. It is less invasive than surgery, it can restore fertility, it is well tolerated and the recovery time is shorter than that following surgical procedures. This preliminary experience is sufficient to encourage gynecologists to introduce the method in Hungary.
