Predictive Factors of Pelvic Magnetic Resonance in the Response of Arterial Embolization of Uterine Leiomyoma

Predictive Factors of Pelvic Magnetic Resonance in the Response of Arterial Embolization of Uterine Leiomyoma

The purpose of this study is to determine predictive factors in the pelvic magnetic resonance in the response of arterial embolization of uterine leiomyoma.

This study followed symptomatic premenopausal women with uterine leiomyoma who underwent uterine artery embolization (UAE). Treatment was accompanied by magnetic resonance imaging of both the volume of the entire uterus and the leiomyomas one month before and six months after UAE. This patients were treated at the Uterine Leiomyoma Sector of the Department of Obstetrics and Gynecology, Medicine College of the University of São Paulo. In this study, the investigators examined 179 leiomyomas in 50 patients.

Inclusion Criteria:

• ultrasound diagnosis of uterine leiomyoma
• presence of symptoms (menorrhalgia and/or pelvic pain)
• indication for UAE(the desire to keep the uterus and/or contraindications for surgery).

Exclusion Criteria:

• malignant genital neoplasms
• pelvic inflammatory disease
• allergy to iodinated contrast
• coagulopathy, renal failure
• vasculitis
• pelvic irradiation
• pregnancy
• subserosal leiomyoma with a pedicle smaller than 50% of diameter of the fibroid.
