Aim: The aim of the study was to assess clinical outcomes following uterine artery
embolization (UAE) in the treatment of dysmenorrhea and menorrhagia related to pure
adenomyosis. Materials and Methods: This was a retrospective analysis of 14 patients
with dysmenorrhea and menorrhagia related to pure adenomyosis treated with UAE using
polyvinyl alcohol (PVA) between January 2017 and September 2019. The baseline and
3-month and 12-month postintervention outcomes were assessed using Uterine Fibroid
Symptom-Health-Related Quality of Life Questionnaire (UFS-QOL), Symptom Severity Score
(SSS), and magnetic resonance imaging findings. The median age of the patients was
47 years (28–55). The main clinical presentation was dysmenorrhea and menorrhagia,
with a median duration of symptom of 24 (12–84) months. All patients received combined
estrogen-progestin and nonsteroidal anti-inflammatory drugs prior to UAE without clinical
improvement. Results: According to UFS-QOL and SSS results, the score for distress
level was statistically significantly reduced from baseline 4.6 (3.6–5) to 2.25 (1–3.37)
(P = 0. 018) after 3 months, and remained stable 12 months later. The score of symptom
level was statistically significantly reduced from 4 (3.6–5) at baseline to 1.6 (1–3.58)
(P = 0. 018) after 3 months with maintained clinical satisfaction after 12-month follow-up.
The junctional zone was statistically significantly reduced from baseline with a median
of 33.5 mm (19–79 mm) to 25 mm (8–77 mm) after 3 and 12 months (P = 0.046). The incidence
of post-UAE permanent amenorrhea is 71% with a mean age of 49 years. No patient underwent
hysterectomy during the follow-up period. Conclusion: UAE using PVA can improve the
quality of life in patients with menorrhagia and dysmenorrhea related to adenomyosis.
However, larger prospective studies are needed to establish the long-term outcomes
and risk of amenorrhea.
