New Options Can Spare Women From Hysterectomy
March 28, 2000 (San Diego) -- Doctors at Stanford University are using
established techniques in new ways to treat one of the most common gynecologic
complaints as well as one of the most serious obstetrical conditions.
Researchers say these procedures can spare women from having hysterectomies,
either to prevent problems from uterine fibroids or to spare their lives when
they hemorrhage after delivering a baby.
Mahmood Razavi, MD, and his colleagues combined two techniques to treat 10
patients who had a high risk of hemorrhaging during childbirth, which can be
fatal. The standard treatment in these cases, if medications fail, is for
doctors to remove the uterus. In this study, Razavi and his co-workers inserted
a few tiny balloons through a catheter into the groins of these patients just
before delivery. They then moved the balloons up to some arteries in the
"Then the obstetrician delivers the baby, and if the patient bleeds, we
inflate the balloons, which instantaneously blocks the blood flow and stops the
bleeding," Razavi tells WebMD. This gives doctors time to perform the
second part of the procedure: injecting a harmless substance called Gelfoam
into the bleeding arteries to block them off.
That process, known as embolization, takes 20-30 minutes, Razavi says. The
balloons are used to stop the bleeding first, he says, because "we can't
let the patient bleed for that period of time." So far, 10 women have
undergone this two-step procedure, and the uterus was spared in nine.
"This procedure could easily be available in community hospitals,
because these are fundamental techniques that use equipment we can just pull
off the shelves," says Razavi, an assistant professor of radiology at
Stanford University. Since it requires close collaboration between an
obstetrician and an interventional radiologist, "the biggest barriers are
awareness on the part of the obstetrician and the willingness of the
radiologist to get up in the middle of the night, since children come when they
Patient satisfaction is high, he reports: "I still get phone calls and
Christmas cards from some of my patients, and several of them have become
"This procedure has some real potential and will surely help save some
uteruses," says Steven Clark, MD, professor of obstetrics and gynecology at
the University of Utah School of Medicine, Salt Lake City.
Clark, who was not involved in the study, tells WebMD that embolization to
stop postpartum bleeding is not new. What is new is the use of the balloons,
called occlusion. The major drawback is that "it's not usually available in
an emergency. But in those cases in which you can predict a high likelihood of
bleeding and you have a little more time, I think this would be a good
