Tubal pregnancy; Cervical pregnancy; Tubal ligation - ectopic pregnancy
An ectopic pregnancy is a pregnancy that occurs outside the womb (uterus). It may be fatal to the mother.
In most pregnancies, the fertilized egg travels through the fallopian tube to the womb (uterus). If the movement of the egg is blocked or slowed through the tubes, it can lead to an ectopic pregnancy. Things that may cause this problem include:
The following also increase risk for an ectopic pregnancy:
Sometimes, the cause is not known. Hormones may play a role.
The most common site for an ectopic pregnancy is the fallopian tube. In rare cases, this can occur in the ovary, abdomen, or cervix.
An ectopic pregnancy can occur even if you use birth control.
Symptoms of ectopic pregnancy may include:
If the area around the abnormal pregnancy ruptures and bleeds, symptoms may get worse. They may include:
The health care provider will do a pelvic exam. The exam may show tenderness in the pelvic area.
A pregnancy test and vaginal ultrasound will be done.
Human chorionic gonadotropin (hCG) is a hormone that is produced during pregnancy. Checking the blood level of this hormone can detect pregnancy.
Ectopic pregnancy is life threatening. The pregnancy cannot continue to birth (term). The developing cells must be removed to save the mother's life.
If the ectopic pregnancy has not ruptured, treatment may include:
You will need emergency medical help if the area of the ectopic pregnancy breaks open (ruptures). Rupture can lead to bleeding and shock. Treatment for shock may include:
If there is a rupture, surgery is done to stop blood loss and remove the pregnancy. In some cases, the doctor may have to remove the fallopian tube.
One out of three women who have had one ectopic pregnancy can have a baby in the future. Another ectopic pregnancy is more likely to occur. Some women do not become pregnant again.
The likelihood of a successful pregnancy after an ectopic pregnancy depends on:

Most forms of ectopic pregnancy that occur outside the fallopian tubes are probably not preventable. You may be able to reduce your risk by avoiding conditions that may scar the fallopian tubes. These steps include:
