Four-dimensional color Doppler ultrasound can rule out Down syndrome

Down syndrome is also called Down screening. In daily life, it is mainly carried out through some other examinations, prenatal prevention for pregnant women and treatment of low immunity in children to prevent infection. Common sense examination in daily life is very important. Down screening mainly checks some examination-type diseases. It is mainly a method of calculating some risk factors of babies with congenital defects based on the expected date of delivery, weight, age or gestational age of the pregnant woman when blood is drawn.

Mainly those with severe intellectual disabilities and some congenital diseases will cause some economic burden to the family. The four-dimensional color ultrasound is mainly used to diagnose new diseases, mainly facial deformities and other models, so in daily life, one can screen for Down syndrome mentally and the other for appearance.

Down syndrome screening is a detection method that extracts serum from pregnant women, tests the concentrations of alpha-fetoprotein, chorionic gonadotropin and free estriol in the maternal serum, and calculates the risk of giving birth to a fetus with congenital defects based on the pregnant woman's due date, weight, age, weight and gestational age at the time of blood collection. Children with Down syndrome have severe intellectual disabilities, congenital idiocy, tongue-protruding dementia, are unable to take care of themselves, and have complex cardiovascular diseases. They require long-term care from their families, which places a great mental and financial burden on the family.

Four-dimensional color ultrasound diagnosis of fetal congenital malformations mainly includes: fetal facial deformities: such as cleft lip and palate; nervous system: anencephaly, hydrocephalus, microcephaly, spina bifida and meningocele; digestive system: umbilical enterocele, visceral exstrophy, intestinal atresia and megacolon; urinary system: hydronephrosis, polycystic kidney and megacystis, urethral obstruction; other deformities: short limb deformity, conjoined twins, cleft lip, four-chamber heart; too much or too little amniotic fluid, etc.

The above is whether the four-dimensional color ultrasound can rule out Down syndrome screening. Down syndrome screening mainly involves some examination-type diseases. It is mainly a method of calculating some risk factors of babies with congenital defects by combining the expected date of delivery, weight, age or gestational age of the pregnant woman at the time of blood sampling. It may not be detected by color ultrasound, so the two examinations are carried out reasonably every second.
