    Abstract:
    PURPOSE: To evaluate long-term outcomes and factors associated with treatment failure after uterine artery embolization (UAE) in women with symptomatic uterine leiomyomas. MATERIALS AND METHODS: One hundred consecutive women treated with UAE for symptomatic uterine leiomyomas participated. Clinical outcome data (ie, changes in symptoms, menstrual status, subsequent therapies) and satisfaction data were collected. Treatment failure was defined by subsequent major surgery (ie, hysterectomy or myomectomy), a second embolization, or a lack of symptom improvement at the patient's final follow-up interval. Possible predictors of failure were age, clinical baseline characteristics (ie, bleeding, pain, and bulk), and imaging results (eg, percent volume reduction of the dominant tumor). Cox proportional-hazards analysis was used to determine factors associated with failure. RESULTS: Follow-up was available in 93 women (median follow-up, 54 months; range, 45-87 y). Continued symptom relief was observed in 72% of patients (n = 67). Among the 26 women with treatment failure (28%), 11 (42%) underwent hysterectomy, four (15%) myomectomy, and eight (31%) repeat embolization. Three (12%) reported no improvement. In women without any additional surgery (n = 70), heavy menstrual bleeding, pain, and bulk-related symptoms improved in 97%, 93%, and 92%. Ninety percent of all women (n = 93) were satisfied or very satisfied at final follow-up. Predictors of failure were a lack of improvement in bleeding (hazard ratio [HR], 9.0; 95% CI, 3.1-26.3; P < .001) or pain (HR, 7.4; 95% CI, 2.2-24.4; P < .001) at 1 year after UAE and the percent reduction in dominant tumor volume (HR, 0.97; 95% CI, 0.95-0.99; P = .007). CONCLUSIONS: UAE in women with symptomatic leiomyomas leads to long-term symptom improvement. Predictors of failure were a lack of improvement in bleeding or pain at 1 year and the percent reduction in dominant tumor volume.
