According to statistics from the Unified Health System (SUS), the variety of hysterectomies amongst Brazilian girls is excessive, representing the second highest fee of feminine surgical procedure after caesarean sections. Vascular and endovascular surgeon, Josualdo Eusebio Silva, famous that the variety of girls who take away the uterus is alarming, as a result of it’s a disfiguring intervention, which in most of those instances can be prevented with a quite simple and minimally invasive process: embolization .

Full or partial elimination of the uterus continues to be extremely practiced in Brazil and overseas. Notifications in the United States, for instance, attain 200,000 instances per yr, and Brazilian estimates are between 200,000 and 300,000 annual occasions, with three deaths per thousand procedures.

Surgeons present that fibroids symbolize about 60% to 70% of those procedures, and about 50% of Brazilian girls have or may have fibroids sooner or later in life, and greater than 1/3 of them are in the reproductive section, that’s, up to 38 years. Fibroids are benign tumors in the muscular wall of the uterus.

They clarify that embolization has turn into a helpful approach and is more and more gaining floor in medication as a girls’s well being care option. The process was launched in France in 1994 and is broadly used round the world due to perceived outcomes.

A myomectomy is the elimination of a fibroid and also can be executed through video, though it’s nonetheless invasive, whereas embolization makes use of a microcatheter to protect the uterus and future pregnancies.

Embolization entails introducing a catheter via a small reduce in the uterine artery, groin, or arm, which feeds the myoma, executing embolization with the launch of small particles, embolic brokers, blocking this sustaining artery to slowly shrink the myoma. .

There are quite a lot of supplies to be utilized in intervention, various from case to case. A process to intentionally block the blood vessels that provide fibroids is an various to surgical elimination to stop signs of heavy menstrual bleeding, ache, or compression of the bladder or bowel.

Embolization makes use of imaging strategies to information the interventional process. Unlike conventional surgical procedures, it isn’t needed to use incisions. The surgeon makes use of X-rays, CT scans, or ultrasound pictures to pinpoint the space.

“Decreased circulation to the website leads to fast and painless enchancment in signs. Approximately 90% of ladies expertise reduction from signs with this system. The total process is carried out in a hospital setting, with native anesthesia or spinal block and even common anesthesia, relying on the anesthetist’s evaluation”, he explains. “The affected person is discharged sooner, and may return to regular work ahead of a hysterectomy,” he says.

Surgeons word that embolization permits the interplay of assorted medical traits to point out the greatest remedy in every state of affairs. A gynecologist is an skilled in deciding the remedy of fibroids, resembling hysterectomy, elimination of fibroids, use of hormones or embolization.

The drawback happens as a result of the myoma grows and occupies area in the uterus, increasing the uterus and may impede implantation. The situation doesn’t imply an impediment to conception; However, it is a complicating issue, as the new approach preserves organs and doesn’t trigger scarring.


Removal makes being pregnant inconceivable and myomectomy, which regularly leaves a major space of ​​the uterus scarred. Embolization protects the uterus, but it surely doesn’t assure fertility, though it’s a much less invasive option, with out bleeding and with out the want for blood transfusion.

It is necessary to underline that, though it is a much less invasive approach, it presents dangers and in some instances, elimination of the uterus is important, it’s important to coordinate with a gynecologist to point out the greatest remedy and for postoperative management. .

Embolization is broadly utilized in endovascular surgical procedure, in lots of areas of drugs, resembling arteriovenous malformation, to regress tumor dimension and facilitate surgical procedure, the use of embolization with chemotherapeutic brokers, in case of vascular trauma with tough bleeding management.

Understand the course of

1- The femoral artery is punctured. A information wire is launched into the uterine arteries after which a catheter

2- Contrast medium is injected to determine the arteries supplying the fibroid

3- Polyvinyl (PVA) particles are despatched to block irrigation

4- Without blood, myoma dries up, signs disappear


• No surgical incision is required, solely a puncture in the groin or arm, the place the catheter and embolizing materials are inserted. Medical procedures resembling laparoscopic surgical procedure and robotic surgical procedure are trending towards minimally invasive strategies.

• Patients sometimes return to regular actions a lot sooner than surgical procedure, as massive incisions with much less tissue trauma usually are not required.

• Approximately 90% of ladies expertise vital or full decision of fibroid-related signs (bleeding or compression signs associated to the dimension of the fibroid).

• On common, fibroids will shrink to half their unique dimension. Most importantly, they turn into softer after embolization and don’t put stress on the adjoining pelvic organs.

• Studies have proven that it’s uncommon for handled fibroids to develop again or develop new fibroids after uterine fibroid embolization. This is due to the truth that each one uterine fibroids, even early-stage tumors that may be too small to be seen on imaging exams, are handled throughout this process. Uterine fibroid embolization is a extra everlasting resolution than the hormone remedy option, as fibroids often develop again when hormone remedy is stopped.

Embolization: The approach treats uterine fibroids

Illustration illustrates the course of. Through a groin puncture with the insertion of a really high quality diameter catheter into the artery supplying the myoma, microparticles are injected to cease the irrigation of the myoma, leading to its entrapment.
