I don't know anyone who has had kids afterwords, and frankly, although I admittedly don't know a whole lot about UA embos, I would likely not do it if I wanted more babies. Unless the fibroid was compromising my fertility.
The idea behind it is to find the feeder artery to a fibroid, using xray dye and xray. Once you plug that artery (embolize it), the blood flow to the growing fibroid cuts out, so the fibroid should shrink.
The whole uterus does not have its blood flow cut, just the artery leading off to the fibroid. It works in most cases, with regression of the fibroid taking place slowly over a year.
Most women complain of severe cramping and some pain after the embo, as the fibroid has had its oxygen supply cut--so it is...dying? for lack of a better word. After that initial pain, most people seem to do ok.
HTH! I know that they have a great program at the hospitals in your town.
