ContextUterine myomas are benign tumors that mostly occur in women of reproductive age at a frequency ranging from 20 to 25%. The symptoms are increased menstrual flow, pain and compressive signs. New treatments have been proposed and uterine artery embolization is one of them.ObjectiveTo evaluate the effects of treatment by embolization of the uterine artery, in women with symptomatic myomas. Uterine and dominant myoma volumes and the major symptoms were evaluated before treatment and 12 weeks later.Type Of StudyOpen clinical trial.SettingA tertiary-care women's hospital.ParticipantsThe study was conducted on 32 women with symptomatic single or multiple myomas of the uterine body, seen at the outpatient unit from May 2000 to September 2001.Main MeasurementsThe patients were submitted to gynecological examination and abdominal and endovaginal pelvic ultrasonography, and the examinations were repeated 12 weeks after the first procedure. Uterine artery embolization using PVA (polyvinyl alcohol) particles of 355-700 was performed by catheterization of the right femoral artery in 30 women and by bilateral catheterization in two.ResultsBefore embolization, the mean uterine volume of the 32 women was 455 cm and the mean volume of the dominant myoma was 150 cm . Twelve weeks after embolization, the mean uterine volume was 256 cm and the mean volume of the dominant myoma was 91 cm , with p < 0.01 in both cases. Twelve weeks after the treatment, all the women answered a questionnaire, which showed that 71% had improvement in menstrual regularity, 90% decreased menstrual volume and 81% shortened menstrual duration. The most frequent immediate post-procedure symptoms, established as complications, were pain (100%) and fatigue (34%). One woman had myoma degeneration and was submitted to myomectomy.ConclusionThe significant reduction in uterine and dominant myoma volume confirms the validity of the treatment of symptomatic myomas by the technique of uterine artery embolization in Brazilian women. There was significant reduction in menstrual flow and duration, as well as better cycle regularity in the women studied. The few adverse effects observed in the sample studied mainly involved pain immediately after embolization.
