Transcatheter uterine artery embolization for the management of symptomatic uterine leiomyomas.
Transcatheter arterial embolization has been applied traditionally in obstetrics and gynecology for the emergency control of pelvic hemorrhage, usually after failure of conventional surgical measures. Pelvic trauma is the most common, nongynecologic etiology of uncontrollable pelvic hemorrhage requiring use of this hemostatic technique. Recently, elective transcatheter arterial embolization of uterine leiomyomas has been performed to decrease related symptomatology in an attempt to avoid surgical intervention. Our objective was to review current pertinent data regarding this new therapeutic modality. To this goal, all manuscripts published in the literature regarding this topic obtained from a MEDLINE search for 1966 through September 1998 were selected and reviewed. Additional sources were identified through cross-referencing. Currently, approximately 193 patients worldwide have been managed with this investigational procedure. Main indications include symptomatic uterine leiomyomata with menometrorrhagia, anemia, or pain. Success rates seem promising with a very low failure rate. This procedure results in significant (uterine and leiomyoma) volume reduction of between 20 and 80 percent. Postprocedural pain is common during the first day after the procedure, often requiring intravenous nonsteroidal antiinflammatory drugs and narcotic analgesia. Rare complications include endometritis, pyometra, and uterine necrosis, which may require hysterectomy. Reported follow-up time ranges between 6 and 60 months. Implications on subsequent fertility have not been established. Although successful pregnancies subsequent to this procedure have been reported, because of the unknown long-term effect of this procedure on fertility or perinatal outcome, this technique should not be performed when future fertility is desired. This review suggests that although not currently accepted as standard of care, transcatheter embolization of the uterine arteries can be considered as a nonsurgical technique for the management of appropriately selected patients.

OBJECTIVE
After completion of this article, the reader will be able to explain the current indications and contraindications of transcatheter uterine artery embolization of leiomyomas; to identify the various complications of the procedure and the type of embolic materials used; and to estimate the success rate of this procedure in the current literature.
