Uterine Artery Embolization for Symptomatic Uterine Leiomyoma and Adenomyosis

Background and Purpose: Uterine artery embolization (UAE) is increasingly accepted as an alternative treatment for symptomatic uterine leiomyoma and adenomyosis. The purpose of this study was to compare the outcomes of UAE in 3 diagnostic categories — submucosal leiomyoma, intramural leiomyoma, and adenomyosis — to assist in patient selection for this relative new form of therapy. Methods: The medical records of 43 patients (aged 22 to 54 years) who underwent UAE for symptomatic uterine leiomyoma or adenomyosis were retrospectively reviewed. Magnetic resonance imaging was used for categorization of the patients into the 3 diagnostic categories, and also for objective measurement of the uterine and leiomyoma size, and subsequent imaging follow-up. UAE was performed using polyvinyl alcohol particles. Symptom improvement and complications after treatment were evaluated at gynecologist clinics using monthly questionnaires. The group differences in complete symptom resolution, uterine and leiomyoma size reduction, incidence of complications, and subsequent surgeries were analyzed. Results: The mean duration of follow-up was 10.9 months. Complete resolution of symptoms was achieved in 13 out of 16 patients with submucosal leiomyoma (81%), 3 out of 15 patients(20%)with intramural leiomyoma (p=0.002) and 3 out of 12 patients (25%) with adenomyosis (p=0.01). The average reduction of leiomyoma size in the submucosal and intramural groups was 56% and 29%, respectively (p=0.02). None of the patients died, Severe complications occurred in 3 of 43 patients (7%), including permanent amenorrhea in 2 and pelvic actinomycosis in l patient. The incidence of complications (p=0.17) and subsequent surgery (p=0.67) did not differ significantly among the 3 groups. Conclusions: UAE is an effective treatment for patients with symptomatic leiomyoma or adenomyosis. In this study, patients with submucosal leiomyoma had the best treatment outcome.
