Abstract

OBJECTIVE:

To evaluate pregnancy outcomes, complications and neonatal outcomes in women who had previously undergone uterine arterial embolization.

METHODS:

A retrospective study of 187 patients treated with uterine arterial embolization for symptomatic uterine fibroids between 2005-2008 was performed. Uterine arterial embolization was performed using polyvinyl alcohol particles (500-900 µm in diameter). Pregnancies were identified using screening questionnaires and the study database.

RESULTS:

There were 15 spontaneous pregnancies. Of these, 12.5% were miscarriages (n = 2), and 87.5% were successful live births (n = 14). The gestation time for the pregnancies with successful live births ranged from 36 to 39.2 weeks. The mean time between embolization and conception was 23.8 months (range, 5–54). One of the pregnancies resulted in twins. The newborn weights (n = 14) ranged from 2.260 to 3.605 kg (mean, 3.072 kg). One (7.1%) was considered to have a low birth weight (2.260 kg). There were two cases of placenta accreta (12.5%, treated with hysterectomy in one case [6.3%]), one case of premature rupture of the membranes (PRM) (6.3%), and one case of preeclampsia (6.3%). All of the patients were delivered via Cesarean section.

CONCLUSION:

In this study, there was an increased risk of Cesarean delivery. There were no other major obstetric risks, suggesting that pregnancy after uterine arterial embolization is possible without significant morbidity or mortality.
