Pregnancy after uterine artery embolization for leiomyomata: the Ontario multicenter trial.

Objective: To report on pregnancies and deliveries occurring in a large cohort of women who underwent uterine artery embolization instead of surgery for symptomatic leiomyomata.

Methods: A total of 555 women underwent uterine embolization in a multicenter clinical trial. The primary embolic agent was 355-500 microm polyvinyl alcohol particles with treatment end-point as bilateral stasis in the uterine arteries.

Technical results and effects of operator experience on uterine artery embolization for fibroids: the Ontario Uterine Fibroid Embolization Trial.

Purpose: To document the technical results and spectrum of practice of uterine artery embolization (UAE) for fibroids in the health care setting in Canada. The effects of interventional radiologist's (IR's) experience with UAE on procedure and fluoroscopy time were also investigated.

Materials And Methods: The study involved a multicenter prospective single-arm clinical treatment trial and included the practices of 11 IRs at eight university-affiliated teaching and community hospitals.
