Uterine artery embolization (UAE), is a technique
usually performed by an interventional radiologist. Most gynecologists are not trained
in advanced radiology, so it is usually done by radiologists working with the referring
First developed in France, UAE has been performed in the US since 1995, and the
technique of embolization had been used prior to that to
stop bleeding in other areas of the body and to stop hemorrhaging after
childbirth. Many women are not aware of UAE, however, because their healthcare practitioner
may not know of it yet.
Women can pursue this option without a referring GYN. The process begins with a
basic consultation and initial MRI evaluation by the consulting radiologist to determine
whether the woman is a candidate. If she is, the procedure is usually scheduled
for a later date. It’s performed in the radiology department with the woman
under some mild intravenous sedation. A small catheter is inserted into an artery
in the groin, then threaded into the uterine artery under radiological guidance
using dye. With a visual map of the pelvis and uterine arteries, small sand-sized
pellets of synthetic material are then released. They lodge in the distal ends and
block the blood flow to the fibroid. There have been no adverse effects or allergic
reaction reported from these particles to date. The procedure itself takes about
60–90 minutes. The referring GYN then usually follows up.
Uterine artery embolization works by basically starving the
fibroid to death over the next several months. By mapping the arteries,
UAE technique protects the blood supply to the ovaries, and menopausal symptoms
are much less common than they are following surgery. There may be some pain —
often intense — and cramping during and after the procedure. Women can go
home that afternoon or stay overnight in the hospital for pain management. It usually
takes a few days to a week to recuperate — much less than having the possible
side effects of general anesthesia and surgery. The results occur slowly over the
UAE was originally recommended for pre- or perimenopausal women with symptomatic
fibroids. The procedure was not recommended for women who might want to get pregnant
because it was uncertain how it would affect fertility or what the effects would
be on a pregnant uterus. New data suggest it may be okay in certain cases. Recently
the procedure was reported as helpful also for post-menopausal women whose fibroids
had not regressed with menopause. There is a small chance that cancer can be found
in the uterus or fibroids, so be sure to discuss this possibility with your doctor.
Some women also fail to respond to the technique as desired; the fibroids may also
grow grow back in time or new ones may arise.
Where can you get UAE?
Many hospitals have an interventional radiology suite and some physicians have set
up separate centers. A large proportion have same-day or overnight observation units
— providing round-the-clock nursing care but with the feel of a hotel. Information
on doctors trained in UAE can be obtained on-line from theSociety of Interventional
Radiology (SIR). Many insurance policies will cover the procedure.
Five questions you should ask about UAE
We always recommend that a woman call and ask a few questions or be seen in consultation
before committing to any course of action. Here are some reasonable questions to
ask about uterine fibroid embolization:
- Am I a good candidate for UAE? Do I need to have a pre-procedure ultrasound or MRI?
- When did you start offering UAE? How many do you perform a week? A year?
- What are your statistics on successful shrinkage of fibroids?
(This figure should be at least 40–50%.)
- When do your women patients usually return to work or daily activities?
(Should be in less than a week.)
- What are the side effects of UAE?
(Fever, infection, artery injury, premature menopause. Rate should be under 1%.)
