Dr Nguyen Ha T is the Head of the Imaging Diagnostic Department, Tu Du Maternal Hospital in Ho Chi Minh City, Vietnam for nearly 20 Years. Tu Du Hospital, the leading referral Fetal-Maternal Hospital in Vietnam, is responsible for 70,000 deliveries and thousands of fetal abnormalities a year. Dr Ha is also the Vice President of the Vietnamese Society of Ultrasound in Medicine, which has strong ties to and collaboration accitivites with ISUOG. As a pioneer in the first trimester screening and diagnosis of chromosomal abnormality, managing fetal structural abnormalities and high-risk pregnancy, Dr. Ha has contributed to building up the standard prenatal care in Vietnam as well as trained thousands of Vietnamese doctors in OBGYN Ultrasound and fetal medicine.

Ectopic pregnancy (EP) is characterized by the implantation and development of an embryo outside of the uterine cavity. The overall rate of EP is 1–2% in the general population, and 2–5% among patients who have utilized assisted reproductive technology. Although the overall mortality has decreased over time, ruptured EP is still the leading cause of maternal death during the first trimester with a mortality rate of up to 14%, and also responsible for approximately 5–10% of all pregnancy-related death. Prompt and accurate diagnosis is therefore of paramount importance to reduce pregnancy morbidity and mortality.
An ectopic pregnancy can be classified according to the location that the fertilized egg implants. Tubal EPs are the most common type, constitute over 90% of EPs, and non-tubal EPs comprise less than 10%. In some rare scenarios, the gestational sac can also be embedded in uncommon locations such as the cervix, ovary or abdomen. Furthermore, according to the classification of the European Society of Human Reproduction and Embryology (2020), extra uterine EPs (tubal, ovarian or abdominal EPs) refers to the gestational sac implanted outside of the uterus, while the embryo that is located within the uterus but breaches the endometrial–myometrial junction and extends into the myometrium should be described as uterine EPs (cervical, caesarean scar, intramural and interstitial EPs). Uterine ectopic pregnancies can be divided further into partial uterine EP if the location of the gestational sac inside the myometrium but partially protruding into the uterine cavity, and complete uterine EP if no visible communication between gestational sac and the uterine cavity can be seen.
A comprehensive multidisciplinary approach should be obtained to establish an accurate diagnosis and management of EPs including a combination of accurate history and physical examination. Grayscale and color Doppler ultrasound (US) using both a transabdominal (TA) and a transvaginal (TV) approach are the first-line imaging modality when evaluating these patients. Transvaginal ultrasound is considered the primary diagnostic tool. Moreover, three-dimension ultrasound and MRI are important non-invasive methods in diagnosing partial uterine EPs because they are really useful to define the relationship between the gestational sac and endometrial–myometrial junction. These approaches would also help delineate the location of the gestational sac in equivocal cases. A single measurement of the quantitative β hCG level alone cannot provide sufficient evidence for the suspicion of an ectopic pregnancy. Therefore, serial quantitative β hCG levels correlated with serial transvaginal ultrasound findings are recommended to determine an early intrauterine pregnancy from ectopic pregnancy. A serial abnormal elevated beta β hCG levels can be helpful to suspect abnormal implantation but it should not be a useful marker to identify the locations of EPs.
Treatment strategies are vary depending on different factors such as the location of the pregnancy, hemodynamic status, the gestational age at diagnosis, serum β-HCG level, reproductive history and plan of future fertility. However, the most common interventions for the treatment of EP are medical management with systemic methotrexate and surgical removal of the pregnancy.
Explore the sub-sections on Uterine ectopic pregnancy, Extra-uterine ectopic pregnancy, and other rare sites.
A PUL is defined as occuring when a patient tests positively for pregnancy but the initial transvaginal ultrasound scan is not able to locate the pregnancy. It is currently believed that the best way to manage these cases is by performing risk prediction, for which hCG and progesterone are used as biomarkers.
