Pregnancy Ultrasound Crown Rump Length, More Accurate Prediction of Due Date

Dream - One important examination during pregnancy is ultrasonography (USG). Usually, the doctor will perform USG to determine detailed condition of the fetus, such as fetal age, weight, and other conditions that could be signs of abnormalities.

To find out about that, there are several ways that can be done. One of the most accurate ways to predict the due date is through Crown Rump Length (CRL) Ultrasound or measuring the length from the top of the head to the baby's buttocks.

When measuring the Crown Rump Length of a fetus, in centimeters, it is measured from the top of the head (crown) to the bottom of the buttocks. This CRL measurement can be taken from around six or seven weeks of pregnancy until 14 weeks. The Crown Rump Length method is believed to be more accurate in determining the gestational age. This measurement is very useful for early pregnancy examinations to predict the age of the fetus. This is because after 24 weeks, ultrasound is no longer accurate in determining the age of your pregnancy.

"When using this method of examination, when the length of the fetus's head to buttocks is already 7 millimeters, the fetal heartbeat should be audible. If the heartbeat is not found in the fetus, there is a possibility that the mother may experience a miscarriage without bleeding," said Renita White, a doctor. A mother who experiences a miscarriage without bleeding usually does not know that she has had a miscarriage. "

This is because miscarriage occurs without symptoms and the placenta continues to supply pregnancy hormones, so a mother thinks she is still pregnant. Meanwhile, if the size of the fetus from the crown to the buttocks is less than 5 mm, then a mother is at a higher risk of experiencing a miscarriage or the fetus experiencing chromosomal abnormalities.

"Crown Rump Length Can Detect Abnormalities"

The result of abnormal Crown Rump Length measurements can also detect abnormalities in the fetus. When the measurement of the length from the crown of the head to the buttocks of the fetus is insufficient, there are several possible abnormalities that may occur.

Abnormalities that may occur in the fetus in the womb include:1. Down SyndromeFor this type of abnormality, medical experts have not yet found the cause. Most likely, this syndrome occurs because the baby has an extra copy of chromosome 21.2. Turner SyndromeTurner Syndrome is only suffered by female babies. This syndrome occurs due to the loss or alteration of one of the X chromosomes. When a girl experiences this syndrome, she will not go through puberty unless she undergoes hormone therapy.

3. Trisomy 18 Syndrome

This syndrome occurs when a baby receives an extra X chromosome. This syndrome causes severe developmental delays in the baby. The most heartbreaking thing is that a baby with Trisomy 18 will only live for four days, and only 10% of babies will live until one year old.

4. Trisomi 18 Sindrom

This syndrome occurs due to the presence of an additional chromosome 13. As a result, a baby will experience severe physical disabilities or intellectual disabilities. This syndrome occurs in approximately one baby out of 16,000 births. Report by Salma Rihhadatul Aisy. Source: Parents.
