Ectopic Pregnancy Overview

Study Notes

Ectopic pregnancy is a condition in which a fertilized egg implants outside of the uterus, usually in the fallopian tube, but it can also occur in other locations such as the ovary, cervix, or abdominal cavity. Ectopic pregnancies account for approximately 2% of all pregnancies and can lead to significant complications if not promptly diagnosed and treated. The most common symptoms of an ectopic pregnancy are vaginal bleeding and abdominal and/or pelvic pain, although early ectopic pregnancies may not exhibit any symptoms.

Ectopic pregnancies are often diagnosed during the first trimester of pregnancy, as they cannot develop normally to term and can be life-threatening due to the risk of fallopian tube rupture and bleeding within the abdomen. Risk factors for ectopic pregnancy include a history of sexually transmitted infections, pelvic inflammatory disease, endometriosis, previous ectopic pregnancy or fallopian tube surgery, being older than 35 years, smoking, history of infertility, and use of fertility treatments such as in vitro fertilization.

The diagnosis of ectopic pregnancy is typically made through a combination of blood tests to detect human chorionic gonadotropin (hCG) levels and transvaginal ultrasound imaging. If an ectopic pregnancy is suspected, serial hCG measurements and ultrasound imaging may be used to monitor the pregnancy's progression and potentially detect a rupture.

Treatment for ectopic pregnancy depends on the location, size, and stability of the pregnancy. If the ectopic pregnancy is unruptured and in the fallopian tube, it may be treated with medication such as methotrexate or minimally invasive surgery (laparoscopy). If the ectopic pregnancy is ruptured, emergency surgery (laparotomy) is necessary to remove the pregnancy and repair any damage to the fallopian tube.

In some cases, ectopic pregnancies may resolve on their own, but close monitoring is required to ensure the rupture does not occur. There is no specific treatment to prevent ectopic pregnancy, but early detection and treatment can significantly reduce the risk of complications and improve outcomes.

Ectopic pregnancies can lead to massive hemorrhage, infertility, or death if not recognized and treated promptly. Therefore, healthcare providers should maintain a high index of suspicion for ectopic pregnancy in pregnant patients with vaginal bleeding or lower abdominal pain.
