Uterine embolization consists of blocking the blood supply to the fibroids to cause them to shrink.
A tube called a catheter with fluoroscopic control (real-time vision) is introduced through the femoral artery to the smaller arteries that supply blood to the uterus. An embolization material is then injected which obstructs the flow of blood into the fibroid and eventually reduces it.
More than one session may be needed depending on the size and number of the fibroids.
Generally it is painful, and in some cases, it produces severe pain that may require hospitalisation.
Uterine embolization may be indicated in women who want to preserve their womb but who do not want to become pregnant (as some studies suggest that it may alter the proper development of the pregnancy).
