What are the Different Types of Fibroids?

Uterine fibroids are categorized by their location within the muscular wall of the uterus.

Intramural fibroids are the most common type of uterine fibroids. They develop within the muscular wall of the uterus and tend to grow inward. Intramural fibroids cause enlargement of the uterus and can cause heavy menstrual bleeding, generalized pelvic pressure, increased waist size, and a frequency in urination and/or constipation.

Subserosal fibroids develop under the outside lining of the uterus. They typically don’t cause changes of menstrual flow; however, they may cause symptoms of pelvic or back pain, pressure, and/or bloating.

Subserosal fibroids can have a stalk or stem. These are called pedunculated subserosal fibroids.

Submucosal fibroids develop under the uterine cavity lining. Although they are the least common type, they cause the greatest symptoms. Even small submucosal fibroids can cause heavy menstrual bleeding with clots and gushing as well as prolonged cycles.

Uterine Fibroid Embolization – Non-Surgical Fibroid Treatment

A Major Advance in Women’s Health

Uterine fibroid embolization (UFE), also known as uterine artery embolization, is performed by an interventional radiologist, a physician who is trained to perform this and other types of embolization and minimally invasive procedures. It is performed while the patient is conscious, but sedated and feeling no pain. It does not require general anesthesia.

The interventional radiologist makes a tiny nick in the skin in the groin and inserts a catheter into the femoral artery. Using real-time imaging, the physician guides the catheter through the artery and then releases tiny particles, the size of grains of sand, into the uterine arteries that supply blood to the fibroid tumor. This blocks the blood flow to the fibroid tumor and causes it to shrink and die.

What are the Risks of Uterine Fibroid Embolization?

UFE is a very safe method and, like other minimally invasive procedures, has significant advantages over conventional open surgery. However, as with any medical procedure, there are some associated risks.

A small number of patients have experienced infection, which usually can be controlled by antibiotics. There also is a less than one percent chance of injury to the uterus, potentially leading to a hysterectomy. These complication rates are lower than those of hysterectomy and myomectomy.
