I have seen many reports before about the fact that the four-dimensional examination was normal, but the baby was born with deformities. Therefore, even if the four-dimensional examination is normal, the baby may be born with deformities. What does four-dimensional inspection detect?

Four-dimensional color ultrasound is the most advanced color ultrasound testing equipment, which can detect the development of the fetus very accurately. For example, conditions such as cleft lip, spine, kidneys, heart, and bone development are also important means to eliminate malformations. So why can’t some deformities be detected?

The baby's position in the belly is not fixed. If the baby's hands and feet happen to be retracted during the four-dimensional examination, the examination may not be clear.

This cannot be detected in the belly. Most babies are born with a height of about 50cm, so natural deformities such as dwarfism cannot be detected. If you are worried that the height defects of the parents will affect the children, then this worry is useless, because it cannot be detected at all during pregnancy.

Although hearing has been formed in the womb, it cannot be detected because every baby has a different personality. Even if you talk to and interact with your baby when fetal movement occurs, your baby may not respond to you in time.

Because the baby has his eyes closed when he is in the belly, there is no way to detect it through technical means during pregnancy. If you want to give birth to a healthy baby, it’s best not to be lazy with these things

In addition to these preventions, there are not a single check that should be done during pregnancy, let alone some that are expensive. . Pregnancy examinations are the most timely and clear reflection of the development of the fetus and the physical condition of the pregnant woman, and play a great role in preventing the birth of deformed babies.

The four-dimensional color ultrasound examination is normal. Is it possible that the baby will be born with deformities?

Before answering this question, let’s take a look at an example. Xiao Wang is a primiparous mother. Because she is a mother for the first time, she has to be extra careful. She usually attends prenatal check-ups on time and has done all the necessary prenatal check-up tests. These included NT, non-invasive DAN testing, system B-ultrasound, and four-dimensional B-ultrasound. They did not show anything wrong, but the baby was born with anal atresia, and I really wanted to die. Later, after her second pregnancy, Xiao Wang also had amniocentesis.

Four-dimensional color ultrasound examination only excludes some specific serious organs. Currently, ultrasound screening examination items for fetal major malformations generally include: cranial halo, lateral ventricles, cerebellum, posterior fossa cistern, spine, and neck. Soft tissue, orbit, lips, four-chambered heart, chest, gastric vesicle, intestines, kidneys, bladder, humerus and ulna of both upper limbs, femur and tibia and fibula of both lower limbs, wrists, ankles, umbilical vessels, etc. Due to the limitations of science and technology and individual differences among pregnant women, current ultrasound screening can only detect about 60%-70% of structural abnormalities. After giving this percentage, many mothers will say that there are still 30%-40% of deformities that cannot be detected through examination. Yes, but there is no way. Only through future technological development can this be solved.

In summary, four-dimensional color ultrasound is not a panacea, but those who have the conditions still need to do a four-dimensional color ultrasound. To express it specifically, the four-dimensional color ultrasound here specifically refers to the system screening B-ultrasound, not the headshot taken in a private hospital. . Good luck with your pregnancy.

The four-dimensional color ultrasound is normal. Is it possible that the baby will be born with deformities?

There are many inspections for women during pregnancy, especially the longer the fetus is in the pregnant woman’s belly, the more items that need to be checked, and four-dimensional color ultrasound is also one of them. Many people A question that everyone will ask is that if the four-dimensional color ultrasound examination is normal, does it mean that there is no need to worry about the possibility of malformations in the baby?

Speaking of possibilities, there is still a certain chance of it happening. After all, many people have seen such reports, which makes many mothers very worried that such a thing will happen to them. So The most innocent thing is the fetus.

What does four-dimensional color Doppler ultrasound check?

The four-dimensional color ultrasound examination mainly checks whether the development of the fetus is normal and whether there are developmental malformations in the fetus.

What are the items of four-dimensional color ultrasound examination?

1. The face of the fetus

Observe the measurement of the distance between the fetus' eyes and orbits. You can also observe the soft palate and hard palate in detail, whether the upper lip arc curve is continuous or interrupted, mainly Screening for cleft lip deformity.

2. Fetal neck

Check whether there are any abnormal masses in the fetus, mainly to prevent the fetus from appearing strange after birth.

3. Fetal spine

Check whether the fetal spine is continuous and whether there are any interruptions.

4. Urinary system

Check the fetal system to see if there is hydronephrosis, polycystic kidney disease and bladder malformations.

Fetal malformation examination is divided into these stages

1. The first time is in 3-4 months of pregnancy, which is 11-14 weeks.

2. The second check-up is in April-May, which is 17-20 weeks.

3. The third examination is in May-June, that is, 20-26 weeks.

4. The fourth examination is in July-August, which is 32-34 weeks.

5. The fifth examination is from 9 months of pregnancy to before delivery.

There are different risks at different stages, and it cannot be said that just one examination can accurately detect whether the fetus will be malformed in the future. In short, mothers should pay attention to getting a good rest. If there are no other harmful factors, the fetus will generally not have malformations.

It is really not easy to be pregnant for ten months. I hope every mother can get through this time easily and happily, waiting for the arrival of the baby!

The four-dimensional color ultrasound examination that everyone generally refers to is fetal system ultrasound examination. The four-dimensional color ultrasound is all normal. There will definitely be no major deformities in the baby born, but there is no guarantee of 100% minor deformities. Can’t you detect missing arms and legs in the news?

We often see reports in the news that a certain mother gave birth to a fetus with only one arm or only one leg. If the mother had a four-dimensional malformation, this would definitely be visible. If the patient was not detected after this examination, it would definitely be a serious dereliction of duty on the part of the doctor. Limb loss is a relatively simple test. Therefore, as long as a regular hospital has done a four-dimensional malformation examination, you can definitely see whether there are missing arms or legs.

Can you see your fingers and toes clearly?

According to the requirements of the third-level prenatal diagnosis screening, fingers are not required. Therefore, fingers and toes are not included in the screening scope. In my daily work, I would look at the baby’s fingers and toes. However, since the fetus is often in a fist-clenching state, there is no way to observe it. So I would at least look at my thumb. But due to technical limitations, he said there was really no way to see it. And there are no standard requirements for fingers and toes, so you know.

Can the ears be checked?

Ears are also not included in the tertiary screening for prenatal diagnosis. Ultrasound examination can only see the presence or absence of one auricle. There is no way to check for malformations of the internal auditory canal, and there is no way to judge whether the external auditory canal is abnormal.

What small anomalies cannot be detected?

Fetal system ultrasound also has some limitations, and it cannot completely guarantee that all abnormalities can be detected. Among them, the thyroid gland, internal and external genitalia, and esophagus are not within the scope of screening. Small ventricular septal defects, pulmonary valve and aortic valve stenosis, coronary artery abnormalities, and ectopic pulmonary vein drainage cannot be guaranteed to be seen. Although fetal system ultrasound is not omnipotent, it can still screen for most fetal malformations. For the health of your baby, you must do this examination! The four-dimensional color ultrasound examination is normal. Is it possible that the baby will be born with deformities?

Four-dimensional color ultrasound is one of the most important items in prenatal examination. Its purpose is to check whether the baby is at risk of malformations.

Why is it possible that if a four-dimensional color ultrasound passes with low risk, the baby born will be deformed?

Generally speaking, the accuracy rate of four-dimensional color Doppler ultrasound is as high as 90%. In other words, even if the four-dimensional color Doppler ultrasound passes with low risk, there is still a 10% chance of malformation.

What are four-dimensional color ultrasound doing?

Four-dimensional color ultrasound is generally most suitable to be performed at 22-28 weeks of pregnancy to check whether there are any deformities in the appearance of the fetus, such as generally checking whether the fetus has short limbs, cleft lip and palate, spina bifida, hydrocephalus, and biliary atresia. Internal organs, brain and other examinations.

Four-dimensional color Doppler ultrasound can rule out most babies with malformations, and it is a very necessary project to prepare for prenatal and postnatal care.

What causes deformities in children during four-dimensional color ultrasound examination?

It can be said that all examining doctors cannot guarantee 100% that there will be no problem, and there is no absolute in everything.

If the baby is deformed even after a low-risk four-dimensional color ultrasound, it may be due to these two reasons.

First, doctors lack experience and misdiagnosis

Doing four-dimensional color ultrasound requires very high technical skills from doctors. Therefore, doctors who can perform four-dimensional color ultrasound in general hospitals are professors or even more senior doctors. They have rich experience and superb skills, and generally do not make misdiagnoses.

Therefore, when having a prenatal check-up, you must go to a regular hospital, such as a maternal and child hospital or a provincial people's hospital. Don't go to small clinics or small hospitals.

Second, the maternal diet is improper and the influence of external pollutants

After passing the low-risk four-dimensional color ultrasound, there are basically no major problems.

After completing the fourth dimension, pregnant women will also be affected if their usual diet structure is uneven and some external factors.

For example, pregnant mothers often eat some irritating foods during pregnancy, such as fried and barbecued foods, as well as some foods that are easy to cause allergies, such as seafood. Therefore, there are many things that pregnant women need to pay attention to during pregnancy.

There are also some external factors, such as the smell of new house decoration paint, the smell of chemical pollution from chemical plants, etc. Therefore, if you are a pregnant woman working in a factory, it is best to adjust your position or take leave in advance.

Don’t know. . . When I was in the middle of the Tang Dynasty and was at high risk, I had sheep crossing [tears running], and then I had four-dimensional surgery. The amniotic test is for checking chromosomes, and the four-dimensional test is for checking external abnormalities.

Hello, this is also possible, but the probability will be smaller.

The baby born is indeed deformed. Therefore, even if the four-dimensional examination is normal, the baby may be born with deformities.

This should not happen. Medical technology is very advanced now. I believe it will be a healthy baby
