20-22. weekly 
ultrasound screening

The Hungarian laws in force require 2nd trimester abnormality screening between the 18th and 19th. week, therefore expectant mothers should definitely not miss this examination.
The sizes of the fetal organs continue to grow as the gestational age advances, so it goes without saying that the assessment of fetal structures and chromosome markers with ultrasound also improves.
20-22. weekly ultrasound screening
The 20-22. during the weekly ultrasound screening, we measure the body parts of the fetus and determine the rate of development of the fetus. We observe the vital functions of the fetus, examine the body contours of the fetus, thoroughly and in detail check the integrity and healthy development of the organs and body parts, especially the heart, brain structure and spine of the fetus. We look for the small signs that may indicate the existence of some abnormality or chromosomal error. During the examination, the healthy functioning of the placenta is also checked and the amount of amniotic fluid is determined. If the pregnant woman requests, we perform the extended fetal echocardiogram screening test and test the length of the cervix (cervix measurement) to predict premature birth.
The 18-19. As a supplement to the ultrasound screening performed in week 20-22, we recommend weekly anatomical and extended fetal echocardiogram screening, during which, thanks to the larger fetal size and better visibility, 95% of developmental abnormalities can be screened out, while 94% of serious heart defects can be screened out, so we recommend it to all pregnant women. In addition, there is the possibility of 18-19. week to detect disorders that cannot yet be screened, such as lissencephaly, microcephaly, dwarfism, etc., so it is definitely recommended.

What other useful information does it provide
20-22 weekly ultrasound screening?

The 20-22. during a weekly ultrasound we examine:
  • the pie structure, so-called looking for signs of hematoma (bleeding) and placental cysts. Pancreatic hematoma is seen more often in pregnant women who had spotting bleeding in the 1st trimester. If a hematoma/cyst occupies >20% of the placental mass, the chance of fetal growth retardation increases and more frequent control of placental function is recommended in the 3rd trimester.
  • the pie position, so-called looking for a deeply adherent placenta (a placenta that reaches the inner cervix) and a placenta praevia (a placenta that covers the inner cervix). At this gestational age, we see these placental position abnormalities in 2-3% of pregnant women. In the 3rd trimester, their occurrence decreases with the "migration" of the placenta. The above two positional abnormalities of the placenta do not allow spontaneous vaginal delivery.
  • the placental implantation disorders (placenta accreta, increta, percreta spectrum), which can lead to life-threatening maternal blood loss after the birth of the fetus
  • the freely running umbilical cord vein (vasa praevia) in the area of the cervix presence. This vessel running in an abnormal location can rupture at the same time as the placenta ruptures (e.g. at the start of labor) and can cause serious or even life-threatening fetal blood loss. The exclusion of vasa praevia is therefore extremely important.
  • the benign uterine smooth muscle changes (fibroids) presence, their position and size. Although most fibroids do not cause any particular complaints during pregnancy, large fibroids or fibroids located in the lower segment of the uterus can cause fetal positioning and insertion disorders, and in rare cases can obstruct childbirth.
