How Early Ultrasound Can Detect Ectopic Pregnancy?

By MomMed | 16 August 2022 | 0 Comments


If you experience symptoms of an ectopic pregnancy, regardless of whether you have a positive urine pregnancy test, it is best to consult your local general practitioner or early pregnancy assessment facility (EPAU). Within 24 hours, an ultrasound scan will be scheduled if they determine it is necessary.

A transvaginal (internal) ultrasound scan, in which a specialized probe is inserted into the vagina to provide a more thorough view of the reproductive organs, is likely to be necessary. It's safe to do a transvaginal ultrasound during pregnancy.

A coexisting ectopic pregnancy is uncommon if a pregnancy is detected during the scan, which shows a gestation (pregnancy) sac, a fetal pole, and a beating heart in the uterus (womb). Nevertheless, each scan will be followed by a thorough examination.

If a pregnancy is detected in the uterus, bleeding may be caused by the fertilized egg implanting and developing normally during the pregnancy, or it may be an indication of an approaching miscarriage. A healthy, typical corpus luteum cyst that develops on the ovary following each ovulation may grow and produce pain. Hormonal changes may affect the intestines and bladder, leading you to urinate (pee) more frequently and maybe even feel a bit constipated.



An ectopic pregnancy often begins in the fallopian tube. The ovary, cervix, a caesarean scar, or the abdominal cavity is among of the less common places where it might develop in the vicinity of other nearby organs. In a tubal pregnancy, the sac is frequently completely invisible on ultrasound. A pregnancy of uncertain placement occurs when your doctor cannot see a sac inside the uterus or even the surrounding area.

This will need a choice between treatment for a possible ectopic pregnancy and cautious observation, monitoring, and follow-up with some other ultrasound and hCG levels. Between eight and ten weeks, an ultrasound could most correctly reveal a gestational sac. However, if a gestational sac is in the uterus, an ultrasound must be able to detect it by the middle of the fifth week.

Your doctor will probably assume an ectopic pregnancy if there is no visible pregnancy in the uterus while there is an indication of internal bleeding or a swelling around the Fallopian tubes. Over 70% of ectopic pregnancies are detectable during an initial transvaginal scan, and the majority of these pregnancies are identified as a region of pregnancy tissue, either with or without a gestation (pregnancy) sac, a fetal pole, or a beating heart, that is not located where it should be in the uterus.
A picture of the growing pregnancy is produced using sound waves in the ultrasound imaging procedure. It is a simple, non-invasive operation that may be carried out in one of two ways:


Trans vaginally: The vagina is probed using a scanning device. With the use of transvaginal ultrasound, your doctor can pinpoint the precise placement of your pregnancy. A wand-like instrument is inserted into your vagina to conduct this test. It generates images of the uterus, ovaries, and fallopian tubes using sound waves and transmits those images to a nearby display.


Trans abdominally: Gel is applied to the lower abdomen's skin before the scanner is moved across it. An ultrasound probe is moved over your tummy during an abdominal ultrasound, which can be used to check for internal bleeding or confirm your pregnancy.

Doctors will examine the ultrasound photos to determine the location of the pregnancy in order to diagnose an ectopic pregnancy. These can assist them in figuring out if the patient's symptoms are being brought on by an ectopic pregnancy, a healthy pregnancy, or another issue.


Having no pregnancy inside the uterus or having a gestation sac without an embryo this pregnancy has an undisclosed location (PUL).

Until the pregnancy's location can be identified and a diagnosis made, this designation is used. Many of them won't be ectopic and won't require medical attention.

When there is no pregnancy inside the uterus and there may be a lump near a fallopian tube, an ectopic pregnancy may be suspected.


The doctor's conversation and examination are the initial steps in the diagnosis.

Getting a pregnancy test, either qualitative (shows whether you are pregnant or not) or quantitative (measures hormone levels), is typically the second step. Occasionally, when performing a pelvic exam, the doctor could detect a sensitive lump.

If such an ectopic pregnancy seems suspected, a pelvic ultrasound and blood hormone pregnancy testing may typically aid in making the diagnosis.

An ultrasound can show that there is no pregnancy inside the uterus.


Human chorionic gonadotropin (beta HCG) serum concentrations are also used to diagnose ectopic pregnancy. Pregnancy tests are made to identify particular hormones. During pregnancy, beta HCG levels often increase. This hormone's increase may exhibit an unusual pattern, which may indicate the existence of an ectopic pregnancy.

Laparoscopy may occasionally be required to confirm an ectopic pregnancy diagnosis. In order to inspect the tissues in the belly and pelvis during a laparoscopy and identify the location of the ectopic pregnancy, tiny incisions are made in the abdominal wall.


The most effective test to identify an ectopic pregnancy is transvaginal ultrasonography. An ultrasound device is put into the vagina during this procedure, and pictures of the pelvis are displayed on a monitor. Transvaginal ultrasonography is able to detect the gestational sac in both normal (intrauterine) and ectopic pregnancies, although the results are frequently indecisive. The examination could just show a lump near the Fallopian tubes or somewhere else, which is suggestive but not definitive of an ectopic pregnancy, instead of a gestational sac with an apparent embryo.
