During pregnancy, pregnant women need to undergo prenatal check ups. One of the procedures in prenatal examination is ultrasound examination. Some pregnant women may see a lot of data in the ultrasound report, such as lateral brain width, but many people cannot understand it and do not know what a certain data means or what impact it has on the fetus. So what does the width of the posterior horn of the fetal lateral ventricle mean?
The width of the posterior foot of the lateral ventricle is mainly used as an indicator to predict the development of fetal neurological function. It mainly refers to the width of the posterior horn of the lateral ventricle, and the normal value of the posterior horn width of the fetal lateral ventricle is 7.6 millimeters ± 0.6 millimeters. In general, an increase in this value may be caused by hydrocephalus, fetal spina bifida, or anencephaly. Of course, checking for its width increase is not necessarily an absolute issue, it may be related to the limited growth and development of the fetus, and there may be changes in the later stage. Therefore, it is recommended to have regular follow-up check ups for exceeding the limit.
After 33 weeks of pregnancy, the width of the posterior horn of the posterior ventricle will decrease. If the width still exceeds 14 or 15 millimeters after 33 weeks, a preliminary diagnosis of mild hydrocephalus can be made. So after pregnancy, it is important to have regular prenatal check ups, follow the advice of a specialist doctor, and take appropriate treatment measures in a timely manner.
The widening of the fetal lateral ventricle generally does not exceed one centimeter and is not a big problem. It is usually absorbed as the baby grows up. However, in rare cases such as genetic inheritance, it may not be absorbed. Therefore, pregnant women should not be too nervous and anxious to avoid affecting the development of the fetus. Regular prenatal checkups are sufficient.
