Uterine fibroid embolization effective in cases where focused ultrasound failed

Uterine fibroid embolization (UFE), a minimally invasive interventional radiology treatment for uterine fibroids, provides significant relief of symptoms for women whose focused ultrasound (FUS) treatment failed, according to a study released during the Society of Interventional Radiology's 33rd Annual Scientific Meeting in Washington, D.C. Primary care physicians and gynecologists can feel confident in informing patients that a failed FUS treatment does not require subsequent gynecological surgery.
