Abstract
OBJECTIVE. The purpose of this study was to assess the safety and effectiveness of uterine artery embolization using gelatin sponge particles alone for women with symptomatic uterine fibroids.SUBJECTS AND METHODS. During 38 months, 60 patients (age range, 32-52 years; mean age, 42.5 years) with symptomatic uterine fibroids underwent uterine artery embolization. Only gelatin sponge particles, approximately 500-1000 μm in diameter, were used in all patients. The improvement of clinical symptoms was assessed by questionnaire. Reduction of the largest tumor and uterine volume reductions were assessed using MR imaging. The follow-up period ranged from 1 to 38 months (mean, 10.6 months).RESULTS. Menorrhagia improved markedly or moderately in 41 (98%) of 42 of patients 4 months after embolization and in 20 (100%) of 20 patients 1 year after embolization. Bulk-related symptoms improved markedly or moderately in 31 (97%) of 32 of patients 4 months after embolization and in 19 (100%) of 19 of patients 1 year after ...
