Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.

The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.

The blood vessels commonly interrogated include the umbilical artery , the aorta , the middle cerebral arteries , the uterine arcuate arteries , and the inferior vena cava.

First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.

Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby. Transabdominal ultrasound involves scanning through your lower abdomen. A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel. The gel helps improve contact between the probe and your skin.

Many women have all the traditional pregnancy symptoms like nausea and sore breasts, plus the bloating. For further reading here is a book on Blighted Ovum: Symptoms, Causes And Treatments, Diet And Remedies However, what we are talking about in this case are whether there are specific signs that your pregnancy may be a blighted ovum pregnancy. Blighted ovum symptoms may be few and far between, if you get any symptoms at all and can be totally normal symptoms of pregnancy.

The majority of people who suffer with a blighted ovum do not realise that anything is wrong at all until they have an ultrasound. Your body was producing pregnancy hormones and you were for all intents and purposes carrying the start of a new life. The truth is that it is very difficult, if not impossible, to tell if you have a blighted ovum just by your symptoms and really the only way to know for sure is by having the ultrasound scan done so that they can look at your uterus and determine if there is an embryo present or not or just the gestational sac.

Because the body will still think that you are pregnant, it is entirely possible that you will get through your first trimester without knowing that you have a blighted ovum. Obviously this can be very distressing to get to 12 weeks when you think you are over the worst part and find that the embryo never developed. This is only going to happen though in places where the first scan that you get is not until the 12 weeks mark like in the UK if you do not have a history of pregnancy problems.

The majority of blighted ovum pregnancies are diagnosed much earlier than 12 weeks however, so it is highly unlikely that you will get as far as 12 weeks and then be diagnosed.
