Although there is no guarantee of fertility, some women can safely become pregnant and deliver healthy babies after undergoing uterine artery embolization (UAE) for fibroids, according to the findings of a small retrospective study from Portugal.
Researchers included 74 women between the ages of 29 and 43 years from a single university-affiliated hospital in their study. All of the women had undergone UAE and wanted to become pregnant.
At 4.5 years follow-up, more than half (59.5%) of the women had become pregnant spontaneously and without any medically assisted reproductive techniques. Although the women had been counseled to wait at least 6 months before becoming pregnant, pregnancy occurred as early as 2 months and as late as 22 months after the procedure.
Two-thirds (22) of the deliveries were cesarean, 11 were vaginal, and 2 were preterm at 36 weeks' gestation. Five (15.2%) infants were of low birth weight, a rate the researchers said matches that for the general population of women in their late 30s.
Given that myomectomy can be difficult in women with numerous interstitial and/or submucosal fibroids, and recurrence rates for fibroid tumors may be higher with myomectomy, UAE may provide a fertility-preserving alternative for some women.
