This study followed 40 consecutive women with symptomatic adenomyosis treated with uterine artery embolization (UAE) between 1999 and 2006, assessing junction zone thickness by MRI at baseline and 3 months and capturing long-term symptoms and adverse events using the UFS-QoL questionnaire after a mean follow-up of 65 months. During follow-up, 7/40 (18%) underwent hysterectomy, and among these, junction zone thickness was significantly greater at both baseline and 3-month follow-up, whereas most women with a preserved uterus were asymptomatic. Four patients with preserved uterus had substantial residual symptoms and lower overall quality-of-life scores, and there was no relation between clinical outcome and the presence of additional fibroids. This paper is centrally about endometriosis and/or adenomyosis — it is specifically about adenomyosis treated with UAE and its long-term outcomes, including MRI-based predictors of hysterectomy.

Abstract

Introduction Long-term results of uterine artery embolization (UAE) for adenomyosis are largely unknown. We assess long-term outcome of UAE in 40 women with adenomyosis.

Materials and methods

Between March 1999 and October 2006, 40 consecutive women with adenomyosis (22 in combination with fibroids) were treated with UAE. Changes in junction zone thickness were assessed with magnetic resonance imaging (MRI) at baseline and again at 3 months. After a mean clinical follow-up of 65 months (median 58 [range 38–129]), women filled out the uterine fibroid symptom and quality of life (UFS-QoL) questionnaire, which had additional questions on the long-term evolution of baseline symptoms and adverse events.

Results

During follow-up, 7 of 40 women (18%) underwent hysterectomy. Among these 7 women, the junction zones were significantly thicker, both at baseline (mean 23 vs. 16 mm, P = 0.028) and at 3-month follow-up (mean 15 vs. 9 mm, P = 0.034). Of 33 women with preserved uterus, 29 were asymptomatic. Four patients had symptom severity scores of 50 to 85 and overall QoL scores of 60 to 66, indicating substantial clinical symptoms. There was no relation between clinical outcome and the initial presence of fibroids in addition to adenomyosis.

Conclusion

In women with therapy-resistant adenomyosis, UAE resulted in long-term preservation of the uterus in the majority. Most patients with preserved uterus were asymptomatic. The only predictor for hysterectomy during follow-up was initial thickness of the junction zone. The presence or absence of fibroids in addition to adenomyosis had no relation with the need for hysterectomy or clinical outcome. Similar content being viewed by others
