Embolization Risks

Just because Embolization CAN be done does not mean it is the RIGHT thing to do.

Consider the following:

  • Embolization will NOT remove fibroids from the uterus, but “injects” plastic particles into the uterus to “kill” fibroids
  • Embolization will NOT provide fast relief of symptoms such as bleeding, pain, bladder issues, bloating and distension
  • Embolization will NOT provide a better or faster recovery than LAAM fibroid removal

And most importantly for patients who want pregnancy:

  • Embolization can increase the risk of miscarriage AND
  • Embolization can affect ovarian blood flow which can impact fertility

What Women are Saying

When considering fibroid treatment, there is NO BETTER OPTION than the LAAM procedure performed by CIGC Hyper-Specialists.

Patient from Chesapeake Beach

"After being told that I could only have an open myomectomy or hysterectomy it was a relief to hear some positive. CIGC by the grace of God removed 17 fibroids from uterus. I'm gonna yell to the rooftops about CIGC!"

Patient from San Francisco

"CIGC performed my myomectomy…the entire process was wonderful. My recovery was quick….I only missed a little over a week of work. The incision from the procedure is just a small line..barely noticeable. I recommend CIGC to any who needs to have a myomectomy."

Patient from Africa

"Being out of the country, they made the phone consultation easy. The surgery went well, I barely required pain meds post-op, and you would not even know I had a surgery looking at my abdomen. I have been pain free ever since."

Patient from New York

"CIGC removed 25 fibroids while preserving my uterus all in a minimally invasive way that had me able to caretake for myself the day after surgery…truly a blessing to the medical profession, most of which is quick to suggest hysterectomy. If I did not find CIGC, I am almost certain I would not have my uterus."

LAAM – Laparoscopic Assisted Myomectomy

LAAM is a minimally invasive method to remove fibroids from the uterus from any location or any size or number, with a recovery back to work in 7 to 14 days. LAAM is a proven, powerful option for fibroid treatment for ALL patients that is safe, effective, and has been performed successfully in thousands of patients.

The Top 3 Reasons LAAM is the BETTER OPTION than Embolization

1. Symptom Relief – Immediate
  • In one hour LAAM REMOVES fibroids from the uterus and results in IMMEDIATE symptom relief
  • Symptoms Treated: Heavy bleeding, severe pelvic pain, bloating and distension, frequency of urination, back pain and pressure
2. Recovery and Effectiveness – Faster
  • Patients after LAAM go home the same day from a surgery center, not a hospital, and have a recovery of 7 – 14 days
  • All fibroids are removed enhancing recovery and relief
3. Fertility – Enhanced
  • LAAM decreases miscarriage rates since the fibroids are removed which allows pregnancies to implant and develop normally
  • LAAM will NOT decrease blood supply to ovaries and is a better option than embolization for patients who want both fertility and relief of symptoms with the fastest recovery possible

The Top 3 Reasons UFE is INFERIOR to LAAM

1. Symptom Relief – Prolonged
  • Embolization will take months, years, and sometimes never to decrease the size of the fibroids and relieve all the symptoms that fibroids cause since the fibroids ARE NOT REMOVED.
  • Plastic particles are injected into the fibroids – they are not removed
  • The fibroids can continue to press on the bladder, back, bowel, abdomen, and nerves. Pain is increased after embolization, bleeding takes time to resolve.
2. Recovery and Effectiveness – Prolonged
  • Embolization can increase pain by “killing” fibroids, but symptoms are not immediately relieved as with LAAM which “removes” fibroids
  • Embolization increases vaginal discharge with some fibroids and will not treat others. Embolization will not treat smaller fibroids
3. Fertility – Potentially Impaired
  • Miscarriage Increased* The fibroids STAY IN THE UTERUS, are NOT REMOVED, and can increase the risk of miscarriage
  • Ovarian Blood Supply Decreased^ The plastic beads can travel to the ovaries and block ovarian blood supply, potentially affecting ovarian health and function

*Embolization can potentially increase the risk of miscarriage
^Embolization can potentially decrease blood flow to the ovaries
See reference articles below

Fibroid Symptoms

Patients undergoing LAAM will get immediate relief from fibroid symptoms, including:​

Heavy Bleeding
Back Pain
Pelvic Pain & Pressure
Leg Pain & Swelling
Frequency of Urination
Bloating & Abdominal Swelling
In a matter of one hour or less, LAAM removes all the fibroids from the uterus and returns the uterus to its normal size.

UFE vs. LAAM Explained

LAAM provides immediate relief of symptoms while preserving fertility. Embolization should NOT be used for fertility.

Embolization and LAAM

How They Work



Embolization is a minimally invasive procedure in which plastic “beads” are injected into the arteries that supply fibroids with blood. The plastic particles decrease the blood supply to the fibroids, ultimately killing them.  Over time, the fibroids decrease in size, however all fibroids may not respond well to embolization.  Larger fibroids have poorer results than smaller fibroids.  Fibroids near the lining of the uterus will discharge foul smelling material through the vagina.  Fibroids on stalks are often not treated well with embolization and respond poorly.  Embolization is not good at treating many fibroids in the uterus, and in general will only treat larger fibroids.  Smaller fibroids can grow and increase in size over time since they are not treated.

Death of the fibroids often results in pain due to uterine contractions.  Embolization does NOT remove fibroids, meaning that the symptoms from fibroids are not treated immediately.  Since fibroids remain in the uterus, an increase in miscarriage rates can occur with fibroids on or near the uterine lining where the pregnancy implants or grows.  The plastic beads from embolization can back up into the ovaries, decreasing blood supply to the ovaries and affecting ovarian health and function.

LAAM Myomectomy

Myomectomy is a surgical procedure that removes fibroids. The CIGC Laparoscopically Assisted Abdominal Myomectomy (LAAM®) is a minimally invasive surgical procedure that can remove fibroids of any size and allow patients to go back to work in two weeks.

Benefits of Myomectomy

With LAAM myomectomy, there is immediate relief of symptoms since the fibroids are completely removed in a one hour procedure, and in general most all fibroids are removed with this procedure. Bleeding, pelvic pain and pressure, back and leg pain, and frequency of urination are completely resolved after LAAM. Since LAAM removes fibroids, it will decrease miscarriage rates – the ability of the pregnancy to implant and grow is better with LAAM since the fibroids are removed and pregnancy success is increased. LAAM will NOT affect ovarian blood supply so that ovarian health and function is normal. Embolization can decrease ovarian blood flow in some patients, which can compromise ovarian health.

CIGC’s LAAM Myomectomy

LAAM is a minimally invasive surgical procedure performed by CIGC fellowship-trained surgeons. CIGC has performed LAAM extensively and currently has the largest published data series on this procedure, comparing LAAM to robotic, laparoscopic, and open surgery with far better results.

LAAM surgery uses a small incision, usually 1-1.5 inches in size in the bikini line. LAAM procedures remove fibroids from the uterus and do not affect the ovarian blood supply. Removal of the fibroids treats the symptoms of fibroids immediately.

CIGC, LAAM, and Value-Based Care

CIGC is focused on providing patients the highest quality of care, the fastest recovery, and the least amount of pain at the lowest possible cost. For patients with fibroids, the LAAM procedure is a revolutionary treatment approach that is superior to UFE. LAAM is performed in a surgery center setting that is safer, far more convenient and patient-friendly, with much lower cost than hospital-based procedures. LAAM myomectomy is the procedure of choice for any patient that desires to become pregnant or wants the best option for treatment of fibroid symptoms immediately, safely and effectively.

Superior Surgical Outcomes Published in Top Medical Journals

The LAAM procedure has been proven superior to other minimally invasive techniques and open surgery. In addition, we have shown that these procedures can be performed safely and more efficiently in an ambulatory surgery center. Our nationally and internationally renowned techniques have been published in prestigious medical journals due to exceptional patient outcomes.

Important Points on Uterine Fibroid Embolization (UFE) and LAAM

Discover the risks associated with pregnancy and menopause. (see corresponding numbered references below)


UFE should not be used on any patient who wants to become pregnant since UFE can decrease pregnancy rates and increase the risk of miscarriage and other complications in pregnancy. (4,5,8)

UFE can significantly decrease blood supply to the ovaries, which significantly affects ovarian egg reserve (studies showed a significant decline in egg numbers in the ovaries) and decrease pregnancy rates. (1,2,3,6,7)

Decreased blood supply to the ovaries will also increase the risk of menopause. (1,2,3,4,5,6,7,8,13)


LAAM is the procedure of choice for fibroid removal in pregnant patients.

LAAM can increase pregnancy rates and enhance fertility. LAAM does not decrease blood supply to the ovaries. With the LAAM technique, all the fibroids, including submucosal ones, are removed.

Women who underwent myomectomy had a greater pregnancy rate. Pregnancy is significantly more common after myomectomy, while a miscarriage risk was higher after UFE (Uterine Fibroid Embolization). (4,5)

Fibroid Symptom Relief

UFE will NOT immediately treat many symptoms of fibroids and may require months or years – or possibly never – to eliminate those symptoms. Therefore, patients will need reintervention in the future. (7,9)

LAAM procedures provide immediate relief of symptoms with a one-hour procedure. All the fibroids are removed, thereby eliminating the symptoms of fibroids in one session.

Recovery and Complications

UFE does not have a faster recovery than LAAM myomectomy.

LAAM provides a faster recovery in most cases, with far less pain.

The rates of unscheduled visits and readmission are higher in UAE than with surgical interventions. (9)

5. Edwards R et al. (2007): The REST trial reported seven pregnancies after UAE at 12 months which included four miscarriages, two live births, and one intrauterine fetal death at 33 weeks. For women with submucous fibroids, the group who underwent myomectomy had a greater pregnancy rate (40.4%) than those who did not undergo surgery (21.4 percent).

7. Hartmann KE et al. (2017): Rates of ovarian failure after UAE (defined as a follicle-stimulating hormone level greater than 40 IU/L at 1 year after treatment) have been reported to be as high as 12% and 18% at 12 and 24 months. Rates of reintervention (with hysterectomy, repeat embolization, myomectomy, medical management, or endometrial ablation) as high as 19–38% have been reported 2–5 years after UAE. Major complications of UAE have been reported in 1–12% of cases and may include unplanned hysterectomy, rehospitalization, ovarian failure, and pulmonary embolism. Minor complications occur in 21–64% of cases and are variably defined among different UAE studies. Minor complications may include pain, fever, and nausea associated with postembolization syndrome; vaginal discharge; and pelvic infection.

8. Homer H, Saridogan E. (2010): Compared with expectant management and matched for age and leiomyoma location, uterine leiomyoma treatment with UAE is associated with an increased risk of pregnancy loss (35.2% versus 16.5%; OR, 2.8; 95% CI, 2.0–3.8), a cesarean delivery (66% versus 48.5%; OR, 2.1; 95% CI, 1.4–2.9), and postpartum hemorrhage (13.9% versus 2.5%; OR, 6.4; 95% CI, 3.5–11.7).

9. Gupta JK et al. (2014): The risk of requiring further surgical intervention within 2 years after UAE has been reported to be twofold to fivefold higher compared with hysterectomy or myomectomy. Compared with any type of surgery for uterine leiomyomas, UAE is associated with similar rates of major postprocedural complications (OR, 0.65; 95% CI, 0.33–1.26); however, UAE has a higher rate of minor postprocedural complications (OR, 1.99; 95% CI, 1.41–2.81). The rates of unscheduled visits and readmission are higher in UAE than with surgical interventions.
