Pregnant mothers can perform an ultrasound test of the foetal aneurysm during the 18-24 week of pregnancy if they want to know about the development of the foetal heart and whether it is combined with congenital cardiac malformations. At this stage, the foetal heart structure is clear, most congenital cardiac malformations have been formed and, at this time, a relatively high volume of sheep water is a good observation of the foetal heart.
I. Is there a harm in performing an ultrasound check?
Many mothers care about the radiation from fetal ultrasound. The fetus ultrasound is based on the use of ultrasound resonance, where ultrasound pulses constantly penetrate the chest wall, and the heart tissue produces a echo, showing the heart structure on the screen. The fetal ultrasound is therefore an ingenuity, safe and reliable method for the diagnosis of pre-cardiatric diseases, which allows detailed observation of the structure and function of the foetus ‘ s heart in the prenatal period.
II. What should be done to detect foetal preconceptions?
Once an ultrasound examination reveals that the foetus suffers from a preconception, mothers and fathers are often anxious and helpless, but blind terminations of pregnancy should be avoided. At this point, there is a need for timely visits to the cardiovascular and foetal medicine sections of the child and for consultations with the relevant doctors. In fact, it’s good for a child to find out earlier and be more active! At present, with the development of pediatric heart therapy, many pre-cardiatric diseases are more likely to be treated with root causes, such as loss of space, loss of room spacing, loss of room spacing, single-heart room, tricardial room, constriction of the aorexus, loss of the right-room double-exit, inverted pulmonary anatomic insulation and loss of space spacing of the more developed valves; termination of pregnancy at the appropriate time with respect to serious pre-cardiatric disorders, which cannot be cured after birth, recommendations of poor post-pregnosis, such as left-cardial development syndrome, some types of permanent artery, single-cardiology, and three-strength valve locks;
III. Does the method of delivery have an impact on the pre- and post-pregnancy of the foetus?
Preconceptions of the foetus are most likely to be carried out in a favourable manner, with the exception of serious pre-cardiatric diseases, especially those on which the artery is dependent, with the exception of obstetrical factors, and the method of delivery is not pre-emptive.
IV. What should we do when induced?
Even if induced abortion is necessary, it is recommended that it be accompanied by a genetic examination of the foetus to guide the next pregnancy. Common foetal genetic tests include ultrasonicly induced velvet piercing for pregnancy 11-13 weeks and ultrasonicly directed pelvis for pregnancy 16-22 weeks, chromosomal nucleotype analysis and chromosomal microarray analysis.
Limitations of ultrasound motion maps
None of the methods currently used internationally for the detection of foetal cardiac ultrasound exclude 100 per cent foetal heart malformations. For example, total pulmonary inflammation occurs immediately after the birth of avil and respiratory difficulties, and early mortality rates are extremely high, but prenatal diagnosis is very difficult. This is related to the specific pulmonary cycle of the fetus, which makes ultrasound observation extremely difficult by the high pulmonary vascular resistance of the foetus, the low flow of blood within the lung and the small size of the pulmonary vein. Some asked whether it was a doctor’s question that my child had diagnosed the lack of space or the unsealed arterial catheter after birth, and why the ultrasound chart had not been checked. Here, I would like to tell you that normal fetuses are defective room compartments and open artery catheters, which are important blood circulation routes, open to the development of the foetus, so the loss of space in the foetal room and the failure of the artery catheters to close are not diseases. Early closure of the foetal ovulation or artery catheters endangers the life of the foetus.
Summary
With the development of ultrasound treatment techniques, most pre-conceptional diseases can now be diagnosed before birth, with a pre-diagnosis rate of over 90 per cent for complex pre-conceptional diseases. This helps to reduce the burden on families and the community by early detection of pre-conceptions and early and appropriate pre- and post-natal interventions to improve the long-term prospects for children.
