Comparison of Clinical Outcomes of Tris-acryl Microspheres Versus Polyvinyl Alcohol Microspheres for Uterine Artery Embolization for Leiomyomas: Results of a Randomized Trial

In the treatment of uterine leiomyomas, UAE with tris-acryl microspheres was associated with a higher clinical success rate, a lower incidence of tumor enlargement, and no significant differences in adverse reactions and inflammatory response compared with the use of PVA microspheres. Tris-acryl microspheres therefore represent the preferred agent for UAE of uterine leiomyomas.
