Uterine leiomyomas, better known as uterine fibroids, are benign smooth muscle tumors of the uterus.The most common tumor found in the female reproductive system, uterine fibroids are seen in 50-60% of women (rising to 70% by 50 years of age) and, in 30% of cases, cause morbidity due to abnormal uterine bleeding and pelvic pressure.  African-American women have a greater chance of being affected by uterine fibroids, particularly at an earlier age than either white or Asian women. [1]  Uterine fibroids can occur at any time between menarche and menopause but are most common in women 35-49 years of age. They typically resolve after menopause.

Before performing uterine fibroid embolization (UFE), it is important to document the presence of fibroids, usually either by pelvic ultrasound or by MRI. MRI is preferred because of its greater ability to demonstrate individual fibroids and denote their size, location, and number within the uterus.  [1, 2, 3, 4, 5]  It has been estimated that 13,000-14,000 UFE procedures are performed annually in the United States. [6]

In light of the success of embolization in reducing solid tumors and diminishing associated symptoms, uterine fibroid embolization (UFE) is performed to reduce uterine as well as fibroid volume and their associated symptoms. [7, 8, 9, 10, 11]
