Popis: Bilateral uterine artery embolization (UAE) is considered necessary to provide effective treatment for symptomatic uterine fibroids. Occasionally, only unilateral embolization is performed, and this study evaluates these outcomes. As part of a prospective observational study of more than 1600 patients treated with UAE since 1996, there have been 48 patients in whom unilateral embolization has been performed. This study retrospectively reviews clinical response as assessed by our standard questionnaire and radiological response assessed by either magnetic resonance imaging or ultrasound. Two principal groups emerged: the largest, where only the dominant unilateral arterial supply was electively embolized (30 patients); and the second, where there was technical failure to catheterize the second uterine artery as a result of anatomical constraints (12 patients). Favorable clinical response with a reduction in menorrhagia at 1 year was seen in 85.7% (18/21) of those patients with a dominant arterial supply to the fibroid(s). In contrast, in those patients where there was technical failure to embolize one uterine artery, there was a high rate of clinical failure requiring further intervention in 58.3% (7/12). Comparison of the technical failure group with the dominant uterine artery group demonstrated a statistically significant (Fisher’s exact test) difference in the proportion of patients with evidence of persistent fibroid vascularity (p
