Ectopic pregnancy is a serious medical condition that can be life-threatening if not diagnosed and treated promptly. It occurs when a fertilized egg implants and starts to grow outside of the uterus, typically in the fallopian tube. Because this type of pregnancy can be difficult to diagnose, it is important to be aware of the signs and symptoms and to seek medical help if they occur. Ultrasound is commonly used to diagnose ectopic pregnancies, but it is possible for the condition to be missed on an ultrasound.
What is an Ectopic Pregnancy?
An ectopic pregnancy occurs when a fertilized egg implants and grows outside of the uterus, typically in the fallopian tube. This is a potentially life-threatening condition because the growing embryo can cause the fallopian tube to rupture, leading to serious internal bleeding. Ectopic pregnancies can also be associated with an increased risk of infertility if not treated promptly.
Signs and Symptoms of an Ectopic Pregnancy
The most common signs and symptoms of an ectopic pregnancy are abdominal pain and vaginal bleeding. Other symptoms can include shoulder pain, dizziness, and lightheadedness. It is important to seek medical help if any of these signs and symptoms occur.
Can an Ectopic Pregnancy be Missed on an Ultrasound?
It is possible for an ectopic pregnancy to be missed on an ultrasound. This is because an ectopic pregnancy can be difficult to detect, especially in the early stages. Additionally, an ectopic pregnancy can look similar to a normal intrauterine pregnancy on an ultrasound. However, it is more likely to be detected if an ultrasound is performed at least 6 weeks after the last menstrual period, when the embryo is larger and can be more easily seen.
Diagnosing an Ectopic Pregnancy
If an ectopic pregnancy is suspected, a physician will typically order a quantitative human chorionic gonadotropin (hCG) test. This test measures the level of hCG, a hormone produced by the placenta during pregnancy. An elevated hCG level, combined with an ultrasound, can help to confirm an ectopic pregnancy. If the diagnosis is confirmed, the physician will typically recommend a surgical procedure to remove the ectopic pregnancy.
Conclusion
Ectopic pregnancy is a serious medical condition that can be life-threatening if not diagnosed and treated promptly. Ultrasound is typically used to diagnose ectopic pregnancies, but it is possible for the condition to be missed on an ultrasound. If any signs and symptoms of an ectopic pregnancy occur, it is important to seek medical help right away. The physician can then order a quantitative hCG test and an ultrasound to confirm the diagnosis. If the diagnosis is confirmed, the physician will recommend a surgical procedure to remove the ectopic pregnancy.
