Condoleezza Rice, the national security adviser, shares at least one thing with millions of other American women: she had fibroids, benign tumors in the uterus that required treatment.
Ms. Rice, the nominee for secretary of state, entered the hospital for an overnight stay last week to undergo a procedure - uterine artery embolization - that is rapidly becoming an alternative to major surgery for troublesome fibroids.
For most women, fibroids, consisting of muscle and fibrous tissue, are no bother. But for millions of others, fibroids can be so large (in some cases, the size of a melon) or so numerous that they cause discomfort, severe bleeding, anemia, urinary frequency and other symptoms.
What causes fibroids is unknown, although estrogen is known to promote their growth. More than one woman in five age 40 and older has the tumors, with higher rates among black women.
For decades, major surgery - a hysterectomy to remove the uterus or a myomectomy to remove selected fibroids while leaving the uterus in place - was the main therapy for women whose symptoms were not controlled by oral contraceptives or other hormonal therapies. About 30 percent of the 600,000 hysterectomies performed in the United States each year are for fibroids.
With the introduction of technologies like ultrasound, C.T. scans, magnetic resonance imaging and new drugs, however, doctors have in recent years developed a number of alternative therapies.
This year in the United States, about 13,000 women are expected, like Ms. Rice, to choose the embolization technique, which is less invasive than surgery. French doctors first reported the embolization procedure in 1995. Since then, the number of the procedures has grown, in part because of direct-to-consumer advertising by interventional radiologists, who perform them.
Embolization involves injecting pellets the size of grains of sand, made from plastic or gels, into uterine arteries to stop blood flow and shrink the tumors by starvation. The procedure is so named because the pellets are emboli, objects that lodge and stop blood flow. M.R.I. scans are often used to screen out fibroid patients who are not candidates for the embolization procedure.
In performing the procedure, interventional radiologists insert a thin tube into an artery in the groin and thread it up to the main uterine artery in the pelvis. A dye is injected that outlines the smaller arterial branches on an X-ray, producing a map that guides injection of pellets through the tube into the arteries that nourish the fibroids.
"Of the patients we see, at least a third have fibroids the size of an orange or larger," and the size does not influence the outcome of the procedure, said Dr. John H. Rundback, an interventional radiologist at Columbia University.
The procedure, which may be painful, usually lasts 60 to 90 minutes. Most patients also experience intense pain for several hours afterward and stay overnight in the hospital. For some patients, the pain persists for several days, or even two weeks. Surgery for fibroids requires a longer hospital stay.
Additional complications from the embolization procedure can include abscesses and other infections; heavy uterine bleeding; early menopause from the pellets damaging the ovaries; or destruction of the uterus, requiring emergency surgery.
Although the procedure is safe, "there are still significant uncertainties about the procedure, especially in terms of future fertility and long-term outcomes," said Dr. Evan R. Myers, chief of the division of clinical and epidemiologic research in Duke University's department of obstetrics and gynecology.
Judging the safety and effectiveness of embolization compared with to other therapies is hard because randomized controlled studies are lacking and because earlier studies did not report how different symptoms responded to different treatments, Dr. Myers said.
"It is amazing that for a condition as common as fibroids, that has such significant impact on reproductive-age women, there is not a lot of high-quality scientific evidence for many of the things that are done for fibroids," Dr. Myers said.
"There still is no gold standard randomized trial comparing embolization to the other interventions," he added. This is largely because patients and physicians have such strong preferences for one method or another that it is hard to recruit enough patients for clinical trials comparing the embolization procedure to hysterectomy, myomectomy, hormonal and other therapies.
Dr. Myers directs a registry that the Society of Interventional Radiology has created to monitor the outcome of 3,000 women who have undergone the embolization procedure. He said that the effectiveness and complication rates for embolization seem comparable to surgery. But there is insufficient information to draw conclusions about the procedure's safety for women who desire to become pregnant, according to Dr. Myers, the interventional society and the American College of Obstetricians and Gynecologists.
In very rare cases - less than 1 percent - fibroids are cancerous. The cancers usually develop among postmenopausal women and the embolization procedure is not recommended for that group. Biopsies are not routinely performed on fibroid patients before embolization, and even if they were done, biopsies would not be able to detect cancerous fibroids deep in the uterine muscle. So statistically, as more women undergo embolization procedures, the cancers are unlikely to be detected in the very few patients who have them.
"That small risk has to go into the counseling before the embolization procedure," said Dr. Howard T. Sharp, chief of the general division of obstetrics and gynecology at the University of Utah.
Dr. Sharp said he believed that there were probably more cases of cancer than the single report in the medical literature, because doctors often "don't report the bad outcomes."
While some researchers are trying to study the embolization procedure further, others, like Dr. Elizabeth Stewart of the Brigham and Women's Hospital in Boston, are testing another fibroid treatment, the ExAblate 2000 System, that won approval from the Food and Drug Administration last month.
The system, made by InSightec Ltd. of Israel, uses ultrasound to destroy the fibroids with heat and M.R.I. to map the uterine anatomy and monitor the degree of fibroid destruction from a repeated application of multiple ultrasound waves on the tumor. The device centers the ultrasound waves similarly to the way a magnifying glass focuses light.
The patient remains in an M.R.I. machine for about three hours and then can go home. Initial studies found that serious side effects occurred in 2 percent of cases, compared with 13 percent among women who underwent a hysterectomy, Dr. Stewart said. Additional studies are being conducted at a small number of hospitals. The procedure is intended for women who have completed childbearing or who do not intend to become pregnant.
First, take nine white raisins. They have to be white...
I was watching the baby channel last week. A woman with fibroids had a C-Section. When they cut her open the doctor pointed out a fibroid, it was as big as a BASEBALL. BUT he didn't remove it. I couldn't believe he left it in her!
I know they say fibroids are suppose to shrink on their own but it seems to me if you have the patient open and you can see these large tumours you should cut them out.
maybe right after delivery is not a good time to excise a large area - the uterus is thinned out and has a huge number of blood vessels at the surface to nourish the baby - the linear cut of a c-section is one thing, but a whole area? you want to sew it up and get the muscles contracting as fast as you can, to stop the bleeding.

I'm glad they slipped in "although the procedure is safe..." because I was beginning to wonder.
I'm not an OB/GYN, but maybe the nature of the cutting required for a complete excision of the fibroid would make any future pregnancy problematic with respect to uterine integrity, i.e. spontaneous rupture and emergency C-section.
I wouldn't say never :)
FReepmail me if you want on or off my health and science ping list.
Thanks for this article.
I had surgery for fibroids (1 grapefruit size and 3 or 4 smaller ones) in 1997 and felt much better afterwards --- but now I have some back again -
one is 12cm x 10cm and some smaller ones.
No wonder I feel distended...!
I do not want surgery again and hubby and I are still trying for a baby after some miscarriages. I pray every day.
Me neither! Getting rid of that cotton-picker was a blessing and a half!
Multiples run in our family. Big ones, too.
Thanks for posting this. I'm learning a lot.
Ouch! Is that so? I'll keep that in mind for my relation.
We've had myomectomies and hysterectomies, tried different meds. Don't know anyone who's had the procedure that Dr. Rice just had. Glad there's another option for women. I'm just curious about where those little pellets go, if there's any chance they can get back into the bloodstream.
Good luck to you! They spotted a small one in my uterus while I was pregnant last time. The next time they scanned me, post-baby, it was gone.
No they are not complex to remove. They mostly "shell out" of the wall of the uterus. But they can bleed and especially vigorously in a gravid uterus.
NEVER? Not so. If the uterine fibroids have degenerated and cause intractible pain....if the fibroid tumors cause bleeding. In some patients with cancer you should not perform surgery. You may need to irradicate certain uterine carcinomas with intrauterine radiation implants. You have not given your freeper good information, except in that you infer second opinions.
Unless the fibroid is pedunculated (on a stalk) the excision of a large fibroid will result in a gaping raw wound in the muscle of a uterus that is already more vascular because of the pregnancy. The medical literature therefore discourages a fibroidectomy at C-Section because of the increased risk of hemorrhage.
"First, do no harm."
Was it seen on repeated sonograms(ultrasounds), or was it just seen in one image, i.e. could it have been an artifact?
