BACKGROUND: Uterine artery embolization (UAE) has proven to be an effective treatment alternative for women suffering from symptomatic uterine leiomyomas. However, long-term clinical evaluation reveals treatment failure in approximately 25% of patients. To cope with the great variability in the extent of leiomyoma disease former studies are based on the simplifying assumption that the largest leiomyoma mainly causes the symptoms. PURPOSE: To evaluate whether anatomical characteristics in women with a single symptomatic leiomyoma influence clinical presentation and outcome after UAE. MATERIAL AND METHODS: Ninety-one patients with a single leiomyoma underwent UAE. Age, uterine and fibroid volume, fibroid location, and clinical symptoms (bleeding- and/or bulk-related symptoms) were documented. The need for reinterventions (i.e. repeat UAE, hysterectomy, myomectomy) and unchanged or worsened symptoms after UAE were classified as treatment failure (TF). Contrast-enhanced magnetic resonance imaging (MRI) 48-72 h after UAE was available in 38 women. The rate of fibroid infarction was determined and patients were assigned to one of three groups: complete (100%), almost complete (90-99%), or partial infarction (<90%). Cox regression analysis (CRA) was used to determine the influence of morphological and clinical parameters on outcome. RESULTS: Follow-up was available in 79/91 (87%) women (median age, 42 years; range, 33-56 years) at a median of 5 years (range, 3.1-9.2 years) after UAE. Anatomical leiomyoma criteria neither connected to specific clinical presentation nor influenced clinical outcome. Younger women showed a higher risk for TF with every year older lowering the risk by the factor of 0.86 (P = 0.024). Subgroup analysis showed predictive value of fibroid infarction with a cumulative survival free from TF of 91% for complete vs. 0% for partial infarction (P < 0.001). CONCLUSION: Even in women with single leiomyomas, anatomical criteria do not specify clinical presentation or predict clinical outcome. Younger patient age and incomplete fibroid infarction relate to higher rates of TF.
