What you need to know about normal 11 week ultrasound, pregnancy ultrasounds.

Hi there , I hope you all have an amazing Christmas, as you can see on the title I will be explaining all about one of the most important ultrasounds on your baby, the 11 week one, in which we will be talking about the Nuchal Translucency as well, if you want to learn how your baby is developing at 11 weeks stay with me, as usual, all ultrasound images regarding this topic will be on the middle of the post…

At 11 weeks your baby is as big as a Lime, measuring about 4.1 to 5.2 cm long and weighing about 0.25 ounces.

Some of the most common 11 Weeks Pregnant Symptoms are:

Fatigue: Even though you are still under the effects of many hormones you are feeling some of your energy coming back slowly. Until then, give yourself permission to kick back and get some extra rest.

Skin darkening.: Well is about time for you to start noticing a dark line down the center your belly, this is a totally normal pregnancy symptom called the linea nigra. This dark line is caused by hormonal changes and is not permanent, even though you might notice that it stays for a while after you give birth, especially if you breastfeed.

Mood swings: Girl try anything and everything that keeps you calm and happy you really need it right now and remember if is possible, avoid stressful situations.

Leg cramps: The cause of leg cramps are not fully known, however, they can be caused by reduced levels of calcium or increased levels of phosphorus in the blood, leg cramps are painful involuntary muscle contractions that typically affects the calf, foot or both and  are more common at night in the second and third trimester. Drinking plenty of water can prevent leg cramps, and so can stretching your legs during the day. You also want to take a look at your diet to be sure you’re getting enough potassium and magnesium.

Nausea. Should be getting better by now but you still feeling some here and there, be patient, some moms to find relieve taking natural remedies like ginger tea.

Vaginal discharge:  Remember this substance is simply nature’s way of getting rid of bacteria. If it’s colored, tinged with blood, has a foul odor, or causes discomfort to call your doctor for a check-up.

What you need to know about the normal 10 week ultrasound.

What you need to know about the normal 9 week ultrasound.

What to expect on your 11 week ultrasound scan:

As usual, we start with the maternal organs first then the baby…
Remember the 11 weeks scan is still done transvaginally.

At 11 weeks your baby should look more like a human being, legs are clearly seen, the amnion is clearly seen, and the placenta is almost developed completely.

Another view of how your baby should look like, the ultrasound image shows the fetal head, arms, abdomen, and legs.

Can we take a moment to appreciate the most cutest thing you are going to see today, this is how your baby’s legs should look like.

Normal Nuchal Translucency.

And now let’s talk about nuchal translucency ultrasound shall we?

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. In fetuses with chromosomal abnormalities, cardiac defects, and many genetic syndromes the NT thickness is increased.

How is the nuchal translucency measurement done:

*The gestational period must be 11 weeks to 13 weeks and 6 days.
*The fetal crown-rump length should be between 45 mm to 84 mm.
*The magnification of the image should be as follow, the fetal head and thorax occupy the whole screen.
*The presence of the nasal bone, the rectangular shape of the palate anteriorly, the translucent diencephalon in the Centre and the nuchal membrane posteriorly are crucial to take an accurate measurement of the NT.

*Fetal head should not be extended or flexed.
*The fetus should be in a neutral position, with the head in line with the spine. A deviation of this position can lead to false positive or negative of the test.
*Is important to distinguish between fetal skin and amnion to avoid errors.
*The widest part of translucency must always be measured.
*During the scan more than one measurement must be taken and the maximum one that meets all the above criteria should be recorded in the database.

*A value of less than 2.2-2.8 mm is considered normal which means not associated with high risk.

IMG_3796-1       Normal NT.

The blood tests that are combined with the NT on the first trimester screening to rule out genetic and chromosomal diseases are:
*Free BhCG (beta human chorionic gonadotrophin)
*PAPP-A (pregnancy-associated plasma protein A).
The level of these proteins is known to change with certain conditions including chromosome abnormalities.

How the abnormal NT looks on Ultrasound??

IMG_3800-3

Ultrasound image of an Abnormal NT measurement, as you can see on this image the NT was measuring 5.9 mm.

What’s next if you have an abnormal NT??

If your risk is increased then further testing (such as CVS or amniocentesis) should be considered.

Chorionic villus sampling (CVS) is a prenatal test that is used to detect birth defects, genetic diseases, and other problems during pregnancy. During the test, a small sample of cells (called chorionic villi) is taken from the placenta where it attaches to the wall of the uterus.

Amniocentesis is a prenatal test in which a small amount of amniotic fluid is removed from the sac surrounding the fetus for testing. The sample of amniotic fluid (less than one ounce) is removed through a fine needle inserted into the uterus through the abdomen, under ultrasound guidance. The fluid is then sent to a laboratory for analysis. Different tests can be performed on a sample of amniotic fluid, depending on the genetic risk and indication for the test.

Both of these tests have risks you should talk to your doctor if you have any concerns.

OK, guys so this is the shortest way to get you the most important things happening at 11 weeks, with all of this testing you probably need a Baby Moon right now lol, you deserve it…

On my next post, we will continue with the weekly Pregnancy Ultrasounds, I see you there, as usual, thanks for staying till the end.

Abnormal first trimester ultrasound.

Hey guys, welcome to another post, today I want to briefly talk about the Abnormal first trimester ultrasound before I continue to weekly ultrasounds, as usual, I will be including ultrasound pictures on my post, in case you haven’t seen my previous article about Normal first trimester ultrasound I will link it down below:

Normal first trimester ultrasound, scan at 6 weeks of gestation.

First trimester ultrasound measurements, dating, and guidelines…

Pregnancy failure is a common problem in the first trimester with failure rates approaching 25%. A threatened abortion is defined as bleeding and cramping in the first 20 weeks of pregnancy. Ultrasound plays a key role in evaluating women with threatened abortion since HCG levels do not always correlate with a specific diagnosis.

Subchorionic hematoma or Subchorionic bleedings.

img_2982

 

 

Is the most common sonographic abnormality in the presence of a live embryo. Vaginal bleeding affects 25% of all women during the first trimester. In women whose sonogram shows a Subchorionic hematoma, the outcome of the fetus depends on the size of the hematoma, the mother’s age and the fetus gestational age.

If the Subchorionic hematoma appears in the late first or second trimester the risks for miscarriage, stillbirth, placental abruption or preterm labor are increased.

However small asymptomatic Subchorionic hematoma vs Subchorionic bleeding associated with No other complications can resolve by itself.

Anembryonic pregnancy ( Blighted ovum).

img_29751

Is a form of failed pregnancy defined as a gestational sac in which the embryo failed to develop. A large gestational sac without the visualized embryo is unequivocal evidence of a failed anembryonic pregnancy.

Embryonic demise and Bradycardia.

img_2987

img_2988

 

The most convincing evidence that pregnancy has failed is the documentation of embryonic demise. As stated previously, all embryos greater than 5 mm in size should demonstrate cardiac activity. Embryonic bradycardia is a poor prognosticator of pregnancy viability and needs follow up. An embryonic heart rate less than 90 beats per minute, in embryos less than 8 weeks is associated with 80% rate of eventual embryonic demise.

Ectopic pregnancy.

Tubal ectopic pregnancy located at the LT adnexa.

The most reassuring sign that an ectopic pregnancy is not present is the sonographic demonstration of a normal intrauterine pregnancy.

Which means that when the HCG levels are 1500 IU or more an intrauterine pregnancy has to be seen, if not the possibility of an Ectopic pregnancy is really high, Follow up with HCG in blood and Ultrasound are highly recommended.

Patients that are in high risk for ectopic pregnancy have:

*History of pelvic inflammatory disease ( PID )

*Previous ectopic pregnancy.

*Infertility.

*Tubal surgery.

Transvaginal ultrasound has an accuracy of 90% and should be routinely be used in the evaluation for ectopic pregnancy.

A variety of uterine findings can be seen with ectopic pregnancies. The may be empty or contain endometrial fluid collection, this should not be confused with an intrauterine gestational sac.

The most common adnexal finding is a complex mass which represents hemorrhage. Other adnexal findings included a normal adnexa or a well formed adnexal ring with or without a yolk sac or embryo. The posterior uterine pouch or pouch of Douglas should be carefully investigated since complex peritoneal fluid may be the only finding in 15% of ectopic pregnancies.

OK so I am ending my post here, on the next one I will be talking probably about Twin pregnancies, and the following week I will be going week by week on scanning, if you stay until the end, thanks and I hope you come back…

feel free to comment if you have any questions.
