Coil embolization of a tuboovarian anastomosis before uterine artery embolization to prevent nontarget particle embolization of the ovary

Uterine artery embolization (UAE) is being used more frequently as a primary treatment for uterine leiomyoma. Performing UAE in women who desire future fertility is controversial because of the risks of premature menopause and the undetermined effects on pregnancy. The etiology of ovarian failure after UAE is not yet clearly defined, but one of the leading possibilities is nontarget embolization of the ovaries. In this case report, the authors describe a technique of selective coil embolization of a uterine artery-to-ovarian artery communication before UAE performed specifically to protect the ovary from nontarget embolization.
