CEN Ectopic Pregnancy

CEN Ectopic Pregnancy Overview

Pregnancy begins with a fertilized egg. Normally, the fertilized egg attaches to the lining of the uterus. An ectopic pregnancy occurs when a fertilized egg implants and grows outside the main cavity of the uterus.

An ectopic pregnancy most often occurs in a fallopian tube, which carries eggs from the ovaries to the uterus. This type of ectopic pregnancy is called a tubal pregnancy. Sometimes, an ectopic pregnancy occurs in other areas of the body, such as the ovary, abdominal cavity or the lower part of the uterus (cervix), which connects to the vagina.

An ectopic pregnancy can’t proceed normally. The fertilized egg can’t survive, and the growing tissue may cause life-threatening bleeding, if left untreated.

Signs and Symptoms

You may not notice any symptoms at first. However, some women who have an ectopic pregnancy have the usual early signs or symptoms of pregnancy — a missed period, breast tenderness and nausea.

If you take a pregnancy test, the result will be positive. Still, an ectopic pregnancy can’t continue as normal.

As the fertilized egg grows in the improper place, signs and symptoms become more noticeable.

Causes

A tubal pregnancy — the most common type of ectopic pregnancy — happens when a fertilized egg gets stuck on its way to the uterus, often because the fallopian tube is damaged by inflammation or is misshapen. Hormonal imbalances or abnormal development of the fertilized egg also might play a role.

Risk Factors

• Previous ectopic pregnancy
• Inflammation or infection
• Fertility treatments
• Tubal surgery
• Choice of birth control
• Smoking

Complications

An ectopic pregnancy can cause your fallopian tube to burst open. Without treatment, the ruptured tube can lead to life-threatening bleeding.

Treatment

A fertilized egg can’t develop normally outside the uterus. To prevent life-threatening complications, the ectopic tissue needs to be removed. Depending on your symptoms and when the ectopic pregnancy is discovered, this may be done using medication, laparoscopic surgery or abdominal surgery.
