When I was pregnant, I went for a large row malformation examination. As a result, several ultrasound doctors gathered to discuss my ultrasound results. This scene scared me. I just felt my brain buzzing. I just remember that the doctor said to me at the end, "Let's do a fetal heart color Doppler ultrasound again, to be clear." Since I was a medical student,
immediately understood the doctor's intention. But then I discovered that many pregnant mothers have some questions about this fetal heart color Doppler ultrasound. What exactly is fetal heart color Doppler ultrasound? Why am I doing this? Why don't others need to do it? Today we answer one by one. What is
fetal heart color Doppler ultrasound?
fetal heart color Doppler ultrasound is a preliminary prenatal ultrasound screening of the fetal heart from 22 to 28 weeks of gestation. It mainly uses ultrasound imaging technology and color Doppler blood flow imaging technology to observe the general morphological structure of the fetal heart in order to detect most fetuses. Reliable prenatal screening and evaluation for congenital cardiovascular structural abnormalities.
What is the main examination of fetal heart color Doppler ultrasound?
Currently, the International Society of Ultrasound in Obstetrics and Gynecology has standardized the ultrasound screening of prenatal cardiac malformations. The basic items include: heart position, heart rate, heart rhythm, four-chamber view, left ventricular outflow tract and right ventricular outflow tract. For color Doppler ultrasound of high-risk fetuses, the three-vessel plane, aortic arch and catheter arch plane are added to the above-mentioned examination content. Early detection, early diagnosis and early treatment of heart malformations can be achieved.
Under what circumstances must pregnant mothers undergo fetal cardiac ultrasound examination?
We recommend that pregnant mothers with the following high-risk factors have a fetal heart ultrasound examination to ensure the health of the fetus:
maternal factors
1, pregnant women with a family history of congenital heart disease
2, pregnant women with congenital heart disease
3, The mother has a history of abnormal pregnancy, excessive or oligohydramnios, etc.
4, early pregnancy taking teratogenic drugs (such as antipyretic drugs, lithium oxide, dalentine, etc. and certain Chinese medicines) and exposure to teratogenic substances (radiation and new Paint, etc.)
5, mother suffering from diabetes, immune connective tissue disease
6, early pregnancy virus infection (especially TORCH virus)
fetal factors
1, ordinary ultrasound examination found that the fetus has organ abnormalities other than the heart
2, ordinary ultrasound Suspected cardiac abnormalities
3, fetal arrhythmia
4, non-immune fetal edema
5, thickening of the hyaline layer of the neck (NT≥2.5mm)
6, early-onset obvious symmetrical growth restriction
7, moderate to severe amniotic fluid abnormalities
fetal heart What is the role of color Doppler ultrasound?
Approximately 150,000 newborns with congenital heart disease are born in my country every year. If they are not treated, about one-third of the children can die due to serious illness and complex deformities within one year after birth. In order to avoid scenes of family tragedies, and for the health of the baby, it is very necessary to have a fetal heart ultrasound examination before delivery, especially for pregnant mothers with the above high-risk factors.
We recommend that pregnant mothers go to a large hospital as much as possible to find an expert in congenital heart disease to do a special fetal heart ultrasound examination. A comprehensive and accurate fetal echocardiogram report is an important basis for clinicians to predict the condition and formulate treatment plans.
