A clinical audit on the efficacy and safety of uterine artery embolisation for symptomatic adenomyosis: Results in 117 women.

BACKGROUND: Uterine artery embolisation (UAE) is a possible uterine-sparing treatment option for women with unsuccessful conservative management for adenomyosis-related heavy menstrual bleeding (HMB) and dysmenorrhoea.

AIM: To conduct a clinical audit on the efficacy and safety of UAE for symptomatic adenomyosis.

MATERIALS AND METHODS: Retrospective review of 309 women who underwent UAE identified 117 women with magnetic resonance imaging features of adenomyosis (junctional zone thickness ≥ 12 mm). Overall success and HMB control were rated by women. Visual analogue scale (VAS) pain score, Uterine Fibroid Symptom and health-related Quality of Life (UFS-QoL) symptoms score and quality of life score were also used to measure outcome.

RESULTS: One hundred and fifteen women (98%) were available for outcome evaluation. The mean follow-up was 22.5 months. Overall clinical success was achieved in 102/115 (89%) women; HMB control was achieved in 91/104 (88%); dysmenorrhea relief was achieved in 94/104 (90%), with VAS reduction of 6.13 (P < 0.001), Mean symptoms score was reduced from 58 to 17 at 12 months (P < 0.001) and QoL score increased from 42 to 88 at 12 months (P < 0.001). Hysterectomy was performed on six (5%) women. There were three (3%) mild groin haematomatas and three (3%) mild subacute complications (one possible endometritis, two urinary tract infections; all responded to oral antibiotics). Two women had unintended pregnancies which were complicated.

CONCLUSIONS: In this clinical audit UAE was found to be an effective uterine-sparing option for women who had unsuccessful conservative treatments for adenomyosis-related HMB and dysmenorrhoea. There were no major complications. Two women had unintended pregnancies that were complicated.
