What is ectopic pregnancy?About 2 percent of all pregnancies develop outside the uterus, called an ectopic pregnancy. These are nearly always in the fallopian tube. Rarely, an ectopic pregnancy will be located in an ovary or in the cervix, or even in the abdomen. Ectopic pregnancy is more common in women with the following conditions:
- infertility (difficulty conceiving)
- endometriosis - a condition in which the tissue normally inside the uterus grows in other areas of the pelvis.
- sexually transmitted diseases (these can cause infection and scarring in the pelvis)
- tubal surgery
- intrauterine conception device (IUD)
Why is ectopic pregnancy a concern?When the embryo implants in the fallopian tube, usually there is not enough blood flow to keep the embryo healthy and it dies.
What are the symptoms of an ectopic pregnancy?Women with an ectopic pregnancy may have irregular bleeding and often have pelvic or abdominal pain, especially one-sided pain. Tests to detect ectopic pregnancy include the level of a hormone in the blood called human chorionic gonadotrophin (hCG), which may not increase as it normally would. Ultrasound examination (a diagnostic imaging technique which uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs) can show a fetus or other tissue in or near the fallopian tube, or blood collecting in the mother's pelvis. Usually, ultrasound can determine there is not an ectopic pregnancy if there is a fetus inside the uterus. Laparoscopy may also be used to diagnose ectopic pregnancy. This is surgery that uses a lighted tube inserted into the mother's abdomen to examine inside her pelvis and often provides the most accurate diagnosis.
Treatment for ectopic pregnancy:Specific treatment for ectopic pregnancy will be determined by your physician based on:
- your pregnancy, overall health, and medical history
- extent of the condition
- your tolerance for specific medications, procedures, or therapies
- expectations for the course of the condition
- your opinion or preference
- allowing the ectopic pregnancy to heal and be absorbed on its own (only for specific cases). Ectopic pregnancy should not be ignored - always seek a physician's care with any bleeding or pain in pregnancy.
- medication called methotrexate that stops the pregnancy from further development. Methotrexate is most successful when the ectopic pregnancy is diagnosed early.
- surgery (possibly including laparoscopy with salpingostomy or salpingectomy) - a surgical procedure to make a small opening in the fallopian tube and remove the pregnancy. If the tube is damaged, total or partial salpingectomy may be necessary - the removal of all or a part of the fallopian tube.
