Tratamento dos Leiomiomas por Embolização das Artérias Uterinas

Purpose: to evaluate the results of uterine artery embolization (UAE) in the treatment of uterine leiomyomas. Methods: eighteen patients with ultrasonographic diagnosis of uterine leiomyomas were submitted to UAE with polyvinyl alcohol (PVA) particles. The femoral arteries are the access sites until selective catheterization of the uterine arteries. Imaging regarding uterine volume was performed before the procedure and three months after wards. Clinical follow-up was performed at regular intervals after the procedure to assess patient menstrual characteristics and uterine volume. Results: three procedures were technically unsuccessful because of failure of superselective catheterization. Control of menorrhagia and pelvic pain was reported at three months after the procedure by 86 and 60% of patients, respectively. The initial mean uterine volume was 381 cm3 and after 3 months, 263 cm3. The mean uterine volume reduction was 27.4% after three months of follow-up. Clinical and biochemical findings consistent with ovarian failure were observed in three (20%) patients. Conclusions: UAE represents a new therapeutic approach in the treatment of uterine leiomyomas. The risk of ovarian failure after the procedure limits its use to patients aged 45 years or without pregnancy wish.
