Abstract
The aim of this study was to evaluate and compare both ovarian function and menstrual characteristics following uterine artery embolisation (UAE) and surgery. Subgroup of women from a randomised controlled trial. Gynaecology and radiology units in Scotland, UK. Ninety-six women from the randomised controlled trial comparing embolisation with surgery as a treatment for fibroids (REST), which recruited 157 patients (106 UAE; 51 surgery). Seventy-three women undergoing UAE and 23 women undergoing surgery (with ovarian conservation) had serum follicle-stimulating hormone (FSH) measurements taken on day 3 of the menstrual cycle prior to treatment, and at 6 and 12 months post-treatment. Data on menstrual cycle characteristics was also collected. Ovarian failure, as defined by an FSH level of >40 iu/l, and change in duration of menses and length of menstrual cycle. There was no significant difference in the rate of ovarian failure at 12 months between UAE (11%) and surgical patients (18%) (P = 0.44). This finding was not influenced by age. The mean duration of menstrual flow decreased significantly, from baseline to 12 months, by 1.7 days (SD 3.8), (95% CI 0.8-2.6). There was no statistically significant change in mean cycle length at 12 months (0.7 days [SD 4.9]; 95% CI [-0.5, 1.9]). There is no evidence for UAE accelerating a deterioration in ovarian function at 1 year, when compared with surgery. UAE is associated with a decrease in the duration of menstrual flow at 1 year.
