Soeda S, et al. – A unique learning system for uterine artery embolization (UAE), and its feasibility and clinical outcomes for symptomatic uterine leiomyoma and adenomyosis performed by obstetrician– gynecologists in cooperation with interventional radiologists are assessed in this study. UAE performed by obstetrician–gynecologists in cooperation with radiologists can be achieved safely and effectively with acceptable clinical outcomes. Live observation of the procedure performed by skilled radiologists is important and essential to improving the skills and decreasing the fluoroscopic time of obstetrician–gynecologists.
