Question
Hello doctor,
I went to a 26-week-old fetal ultrasound and found a malformation with 11mm and 13mm bilateral ventricular dilatation and no transparent walls (capsular aplasia). The doctor told me to ask the fetus at 26 weeks of fetal dilation of the ventricles, not seeing the transparent wall, is it dangerous? Thank you doctor.

Hello,
With the question "26 weeks pregnant with bilateral ventriculomegaly, is it dangerous to not see the transparent septum? ", the doctor would like to answer as follows:
Aplasia of the corpus callosum is a severe malformation of the central nervous system because the corpus callosum structure is not formed from the embryonic period. The corpus callosum is a large white matter structure that plays an important role in movement, sensation, perception,... The disease may be accompanied by chromosomal abnormalities or, more commonly, genetic or group abnormalities. genes (smaller chromosome level). This malformation mainly causes mental retardation of children. Children have reduced intelligence quotient (IQ), reduced cognitive ability, slower body movement than usual. This disorder cannot be treated and will not go away on its own.
You need to do prenatal diagnosis, ultrasound consultation, do some more tests such as MRI to evaluate other brain abnormalities, amniocentesis to rule out chromosomal abnormalities, non-invasive prenatal screening. From there, doctors of obstetrics, genetics, paediatricians can advise and predict your pregnancy.
To reduce unwanted risks from amniocentesis, Vinmec International Hospital currently applies non-invasive prenatal screening (NIPT). This is the most effective and safe test method available today, performed right from the 10th week of pregnancy through a mother's blood sample. Non-invasive prenatal screening (NIPT) analyzes fetal free DNA in maternal blood to screen for birth defects syndromes that the fetus may have. Just 7-10 ml of mother's peripheral blood to test for Down syndrome, Edwards, Patau,... and many other syndromes for the fetus with high accuracy surpassing conventional tests.
If you still have questions about the 26-week fetus with bilateral ventricular dilatation, no transparent walls, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
