Development Scans

The test combines pathology results from a blood test and a nuchal translucency ultrasound scan, both matched to your age. The CFTS correlates these findings with a likelihood risk to determine if you are at high risk of having a baby with a chromosomal abnormality, such as Downs Syndrome. The CFTS does not directly diagnose an abnormality, but predicts the likelihood of this type of abnormality being present.

Ultrasound uses sound waves to create an image (picture). The sound waves can not be heard and the power of the sound waves used is very low. In pregnancy an ultrasound scan can be used to look at the developing baby, the uterus and the placenta. An ultrasound is safe for both mother and baby.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening. Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.

This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results. This means that combined first trimester screening will not give us a definitive answer.

Chorionic villus sampling and amniocentesis are invasive tests, involving putting needles into the placenta or amniotic sac, and they are associated with an increased risk of miscarriage.

Development Scans

Maternity leave, your rights You at 11 weeks pregnant Now that your body is undergoing so many changes, you might find you have to adapt your existing beauty and skincare routine a bit. Your skin could go either way — mega dry or mega oily! This can either give your skin that lovely pregnancy ‘glow’ or make it blotchy and dry. Hormonal changes and weight gain can cause the usually elastic middle layer of your skin the dermis to breaks in places, allowing the deeper layers to show through.

This is what causes the thin red or purple narrow streaks or lines that define stretch marks. Unfortunately, you are either going to be pre-disposed to getting stretch marks or not, but you can help keep your skin soft and flexible by using one of the many anti-stretch mark products in the chemists — or some women swear by cheap and cheerful cocoa butter or coconut oil!

The aims of the scan: If a dating scan was not done, to date the pregnancy accurately and determine the estimated due date (EDD); If a dating scan was not done, to diagnose multiple pregnancies. Approximately 2% of natural conceptions and 10% of assisted conceptions result in multiple pregnancy; To diagnose major structural abnormalities.

Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself. The baby will be measured, and the anatomy examined in detail. It is recommended that all pregnant women have a scan in the first trimester at around 12 weeks of pregnancy to confirm their dates.

First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as an increased fetal nuchal translucency back of the neck to enable detection of Down’s syndrome fetuses. When is the nuchal fold screening test carried out? The test is performed between 11 weeks and 13 weeks 6 days into your pregnancy. The test cannot be performed outside this time frame as certain features that need to be seen on the scan are not present.

If you are unsure of your period dates or have an irregular cycle, we suggest that you contact your doctor, midwife or health care provider as early as possible to arrange for a dating scan. There is no hard and fast rule for the number of scans you should have during pregnancy. A scan maybe ordered when an abnormality is suspected on clinical grounds.

Nuchal translucency scan

Certificates of competence Nuchal translucency scan Nuchal translucency NT is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. The term translucency is used, irrespective of whether it is septated or not and whether it is confined to the neck or envelopes the whole fetus.

In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes the NT thickness is increased. Early screening for chromosomal abnormalities The Fetal Medicine Foundation FMF has introduced a process of comprehensive training, support and audit for the proper implementation of early screening for chromosomal abnormalities.

OBSTETRIC ULTRASOUND EARLY PREGNANCY (6 TO 12 WEEKS) Dating scan – find out your expected date of delivery. Check viability and position of gestation.

Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome. Why might I have a nuchal scan? All pregnant women are offered an NT scan, to help assess whether or not their babies are likely to have Down’s syndrome.

Every woman has a chance of giving birth to a baby with Down’s syndrome. The chance increases as you get older. A screening test tries to get a clearer estimation of whether your baby may have Down’s syndrome. It can’t tell you for sure. For example, if the result of your scan shows that you have a one in 1, chance, this means that for every 1, babies with your level of likelihood, one will have Down’s syndrome.

A chance of one in or less is considered high.

Nuchal scan

The scan is usually done transabdominally, but occasionally it may be necessary to do the scan transvaginally: The purpose of the week scan: To date the pregnancy accurately. This is particularly relevant for women who cannot recall the date of their last period, have an irregular menstrual cycle, or who have conceived whilst breastfeeding or soon after stopping the pill.

International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not.

How can we interefere in something we do not understand? Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart. One notable exception is Gray’s Anatomy. Gray’s Anatomy describes inflation of the neonatal lungs as the first change after birth and does not describe any changes in the afterload of the heart.

Afterload is the force that the myocardium generates during ejection against systemic and pulmonary vascular resistances. Reductions in afterload increase stroke volume if other variables remain constant. Gray’s Anatomy also describe the release of bradykinins from the pulmonary vascular epithelium which are vasoconstrictors to the umbilcal arteries. A high oxygen tension in the blood reaching the umbilcal arteries also has a vasoconstrictor effect on these vessels.

Those texts that describe the sudden increase in afterload of the heart, explain that this is the result of withdrawal or closure of the placental circulation. Although Hofmeyer did demonstrate a sudden increase in arterial pressure in the healthy neonate in response to the application of a clamp on the umbilical cord 35 seconds after birth there have been no other investigations of the arterial effects of clamping the umbilical cord.

Pregnancy by week

Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome. Why might I have a nuchal scan?

Available to women from 16 years of age. This service includes a Non Invasive Prenatal Test (NIPT for short, sometimes called the Harmony™ prenatal blood test from Ariosa Diagnostics Inc or Vision™ from Future Health Biobank) and an ultrasound scan.

Morgan Griffin Who Gets the Test? The first trimester screening is a safe, optional test for all pregnant women. It’s a way of checking your baby’s risk of certain birth defects , such as Down syndrome , Edward’s syndrome trisomy 18 , trisomy 13 and many other chromosomal abnormalities as well as heart problems. What the Test Does The screening involves two steps. A blood test checks for levels of two substances — pregnancy-associated plasma protein-A PAPP-A and human chorionic gonadotropin.

A special ultrasound , called a nuchal translucency screening, measures your baby’s nasal bone as well as the fluid at the back of your baby’s neck. A high volume of fluid can be a sign of problems. The combined result of the blood tests and the ultrasound gives you a sense of your baby’s risk. However, it’s not a diagnosis.

Development Scans

The first trimester is months one, two, and three of your pregnancy. Below are scan pictures taken during the early weeks of pregnancy. Measurements taken at these early scans will help to; confirm a pregnancy, date the pregnancy and to see any problems that may occur in the pregnancy low lying placenta, twins etc.

How nuchal translucency scan results are calculated. Your baby’s chances of having a chromosomal abnormality are determined by the nuchal translucency measurement, your age, your baby’s gestational age and the blood test results.

What will you do with your scan photos? When will I have my dating scan? You’ll have a dating scan, also known as a week scan between about 10 weeks and 14 weeks of pregnancy. You’ll only have a scan before this, between six weeks and 10 weeks, if you’ve experienced bleeding , pain, or problems in a previous pregnancy Miscarriage Association nd. You’ll also be able to have an earlier scan if you’ve had recurrent miscarriages NICE How accurate are dating scans?

A dating scan is the best way to predict your due date PHE The point of the scan is to work out how many weeks pregnant you are. You may have calculated the length of your pregnancy from the first day of your last menstrual period LMP.

Down’s syndrome Scan

You may like to take a look at charts for crown-rump length , biparietal diameter , femur length , abdominal circumference , gestational sac diameter , yolk sac diameter and intrauterine fetal weight. If you have problems understanding and calculating your due date, check out and download a copy of the Ob calculator by York Winston. Hutchon’s site and the Gestation Network also provide pregnancy calculators.

A large number of mails I received are about fetal anomalies, I have therefore tried to put together a Catalogue of Web pages which describe in some detail specific congenital anomalies that are diagnosable by ultrasound. You can visit the page here.

The Early Pregnancy Scan Dublin 2 costs fr. €95 ( wks) to € ( wks) at Merrion Fetal Health. See Dr Shane Higgins explain about early pregnancy scans in a short video.

Triploidy Other defects with normal karyotype[ edit ] In fetuses with a normal number of chromosomes, a thicker nuchal translucency is associated with other fetal defects and genetic syndromes. The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness.

It is important to distinguish the nuchal lucency from the underlying amniotic membrane. Among those fetuses whose nuchal translucency exceeds the normal values, there is a relatively high risk of significant abnormality. Further, other, non-trisomic abnormalities may also demonstrate an enlarged nuchal transparency. This leaves the measurement of nuchal transparency as a potentially useful first trimester screening tool.

Abnormal findings allow for early careful evaluation of chromosomes and possible structural defects on a targeted basis. How to define a normal or abnormal nuchal translucency measurement can be difficult. The use of a single millimeter cutoff such as 2. Thus for even greater accuracy of predicting risks, the outcome of the nuchal scan may be combined with the results of simultaneous maternal blood tests. In pregnancies affected by Down syndrome there is a tendency for the levels of human chorionic gonadotropin hCG to be increased and pregnancy-associated plasma protein A PAPP-A to be decreased.

The advantage of nuchal scanning over the previous use of just biochemical blood profiling is mainly the reduction in false positive rates. However this procedure carries a small risk of miscarriage so prior screening with low false positive rates are needed to minimize the chance of miscarrying.

First Trimester Screen

The dating scan is usually done at some point between 8 weeks and 14 weeks pregnant. NICE recommends it’s done between 10 weeks and 13 weeks. You will have had earlier appointments and may have had an early scan if you’ve had any concerns such as bleeding , but otherwise this is the first time you’ll get to see your baby, so it’s a real milestone in your pregnancy.

Nuchal Translucency test (12 to 13 weeks) Dating Scan (12 to 16 weeks) Morphology Scan (18 to 20 weeks).

Our sonographers are all accredited by the fetal Medicine Foundation also. Ultrasound scan screening is for Down’s syndrome as well as Edward’s syndrome and Patau’s syndrome and Turner’s syndrome. The ultrasound scan measures the nuchal translucency thickness and the presence or absence of the nasal bone of the baby as the majorities of babies with Down’s syndrome may have an increase in the fluid collection behind the baby’s neck and may also have absent fetal nasal bone. Nuchal translucency measurements as well as the blood test in the first trimester of pregnancy The Combined Test may avoid the needs for amniocentesis.

Our cut-off point for nuchal translucency measurements are: The result of the nuchal translucency scan is given to patients following counseling on the same day. The blood test results in 24 hours. We do not do the blood test at the Brayford Studio Lincolnshire but we can arrange it for you on request.
