PURPOSE: To propose uterine myoma embolization as an alternative to myomectomy or hysterectomy in the treatment of symptomatic myomas; to evaluate the efficacy of the procedure in terms of clinical outcome, adopting all procedural and technical precautions to ensure minimal X-ray exposure and preserve reproductive potential. MATERIAL AND METHODS: Between April 1998 and February 2000, 26 patients, age range 32-54 years (mean 41 years), underwent uterine arterial embolization for menorrhagia, pelvic pain, and sensation of mass and pressure. Inclusion criteria were: single myomas, intramural localization and rich vascolarization of the lesion. Dose to patient was obtained by placing a thermoluminescent dosimeter (Harshaw, Solon, Ohio) both placed in posterior fornix of the vagina and on the skin at the beam entrance site. The procedure was performed under peridural anesthesia; polyvinil alcohol particles 355-500 mu (Contour) (Target Therapeutics, Boston Scientific Corporation, Fremont CA, USA) were employed as embolic agent. The uterine arteries were incannulated with a 5F (Glidecath, Terumo, Europe NV, Belgium) and successively 3F coaxial microcatheter (Target, Boston Scientific Corporation, Fremont CA, USA); the embolic material was injected as distally as possible. Color Power Doppler Ultrasound follow-up before and after i.v. contrast media administration (Levovist SHU 508 A, Shering, Berlin, Germany) was carried out at 15 days, at 1, at 3, at 6 months, and at 1 year from embolization. Pre-procedural evaluation and follow-up at 1 year was performed by MRI using T1 and T2 weighted images before and after Gadolinium (GdDTPA Shering, Berlin, Germany) administration. RESULTS: The technical success of the interventional procedure was 100% (26/26 cases). The mean fluoroscopy time was 20 minutes, and the mean number of angiographic exposures was 10. The mean estimated ovarian dose was 18.75 cGy and the mean adsorbed skin dose was 126.71 cGy. The imaging follow-up showed a 55% reduction of myoma volume at 6 months and a 75% reduction at 1 year. All patients reported a marked decrease in symptoms. No major complications were observed. The appearance of pelvic pain in the 24-48 hours after the procedure required sedation by analgesic pump; transitorial amenorrhea was observed in 3 patients. As for term complications, 2 patients have eliminated necrotic material through the vagina four weeks after procedure. The patients reported great satisfaction with the procedure. DISCUSSION: Many treatment options are currently available for symptomatic uterine myomas. One is surgical myomectomy which is associated with increased blood loss, pain and post operative morbidity and requires an additional surgical procedure for fibroma recurrence in 20-25% of patients. Another alternative treatment is hormonal therapy, which drammatically improves symptoms and reduces fibroid size although leiomyomas regrow to their original size within a few months of discontinuing treatment. Uterine embolization is a relatively new treatment for uterine fibroids that can be considered as an alternative to surgical and medical procedures. The radiation exposure adsorbed by the patient is reduced by using pulsed fluoroscopy and taking all the precautionary measures required to minimize the dose. CONCLUSIONS: The technical success, the patient' satisfation, the short hospitalization time and preservation of fertility confer to uterine artery embolization the role of a new alternative therapy for the treatment of symptomatic uterine myomas.
