Successful embolization of collaterals from the ovarian artery during uterine artery embolization for fibroids: a case report.

JVIR 2000; 11:607–610 UTERINE artery embolization (UAE) (also known as uterine fibroid embolization) as a definitive treatment for symptomatic uterine leiomyomata was first reported in 1995 (1). While this and subsequent reports have shown great promise for the technique, clinical failure has been seen in as many as 20% of patients (2–7). Among that group have been women undergoing unilateral embolization or having arterial supply to their fibroids from sources other than the uterine artery (3,7,8). This report describes a patient in whom the right ovarian artery provided the dominant arterial supply to a uterine fibroid. These collateral branches were selectively embolized via the ovarian artery with use of a microcatheter technique, giving satisfactory clinical and anatomic results.
