An ectopic pregnancy is a pregnancy that grows in a location other than the lining of the uterus. Most ectopic pregnancies (95%) occur within a fallopian tube. Rare locations include on the cervix, in the abdomen, or on an ovary. An ectopic pregnancy cannot survive because only the uterus can support the growth of a fetus and its placenta. If an ectopic pregnancy bursts a fallopian tube, it is a medical emergency that threatens the life of the mother due to hemorrhage in the abdomen. Ectopic pregnancies occur with a frequency of 1 in 100-200 diagnosed pregnancies.
A risk factor is something that increases your chance of getting a disease or condition. Risk factors include:
Symptoms include:
The doctor will ask about your symptoms and medical history, and perform a physical exam.
Tests may include:
Treatment includes:
If diagnosed while the ectopic pregnancy is still small and has not ruptured, methotrexate (a form of chemotherapy) can be given to some patients to prevent further growth of the ectopic pregnancy and avoid surgery.
Emergency surgery is needed if:
This surgery can be done through a laparoscope or an open abdominal incision. During the surgery, the pregnancy will be removed. If possible, the doctor will repair your fallopian tube. In some severe cases, the fallopian tube may need to be completely removed.
If you are diagnosed with an ectopic pregnancy, follow your doctor's instructions .
To reduce your risk of ectopic pregnancy:
About 50%-85% of the women who have experienced one ectopic pregnancy are later able to achieve a normal pregnancy. A subsequent ectopic pregnancy may occur in 10%-20% of cases.
Infertility occurs in a high percentage of women who have experienced an ectopic pregnancy. Often these women can be helped by an infertility specialist.
The maternal death rate from an ectopic pregnancy in the US has decreased in the last 30 years to less than 0.1%.
