How to prevent the widening of the posterior horn of the right lateral ventricle in the fetus

We all know that when pregnant women do fetal fetal anomaly screening in the second trimester, they will use four-dimensional color ultrasound to monitor the width of the fetal ventricles. If the ventricles widen by more than ten millimeters, it means there is a risk of hydrocephalus. Once hydrocephalus is suffered, doctors generally recommend that the mother terminate the pregnancy. This will have a certain impact on the physical and mental health of the mother. However, if some prevention methods can be mastered, such things can be effectively avoided. Let's learn how to prevent the widening of the posterior horn of the right lateral ventricle of the fetus.

The normal size of the fetal lateral ventricle should be less than 1 cm. 1 to 1.5 cm is considered mild, and more than 1.5 cm is abnormal. Hydrocephalus refers to the excessive accumulation of cerebrospinal fluid in the ventricular system, which causes the expansion of the lateral ventricular system and increased pressure, and manifests as enlarged ventricles on ultrasound examination. Generally, a widening of the trigone of the lateral ventricle by 1.5 cm is considered ventricular enlargement, and the wider the area, the more serious the enlargement. If the triangle is 1.2 to 1.4 cm wide and the choroid plexus occupies more than 50% of the ventricle, it is generally considered normal. If the choroid plexus is shrunk and becomes suspended, hydrocephalus is considered to be present.

There are many causes of hydrocephalus. In addition to excessive production of cerebrospinal fluid, it is also caused by absorption disorders or blockage of the cerebral aqueduct. Certain diseases such as intracranial hemorrhage, infection, etc., their sequelae can lead to hydrocephalus, and hydrocephalus can occur at any time during pregnancy. Therefore, even if the brain development is normal in the second trimester, hydrocephalus may occur in the third trimester. Therefore, ultrasound examination during pregnancy is very necessary. In addition, some situations may be mistaken for hydrocephalus. Experienced ultrasound doctors will compare relevant factors and make a well-founded diagnosis. Mild abnormalities found during pregnancy can be accurately diagnosed through dynamic observation.

The widening of the lateral ventricles is mostly caused by excessive cerebrospinal fluid in the fetus. Most of them can be absorbed by the fetus in the later stage. Do a B-ultrasound every few weeks to see if it continues to widen. Another point is that if the lateral ventricles widen too much, the doctor will suspect hydrocephalus. In addition to the widening of the ventricles, there is another obvious accompanying symptom of hydrocephalus, which is spina bifida. So when you do a B-ultrasound, let the doctor help you to see clearly whether the fetus has spina bifida. If not, the fetus should be healthy.

How to prevent the widening of the posterior horn of the right lateral ventricle in the fetus

1. Ensure safe delivery and prevent suffocation and birth injuries. When a pregnant woman is giving birth, she must do so in a hospital with good environmental conditions. She should not delay the delivery process and should be careful to prevent perinatal asphyxia and birth injuries. This is an important step in preventing the occurrence of perinatal hydrocephalus.

2 Strengthen early prenatal diagnosis and early termination of pregnancy to prevent the birth of children with hydrocephalus. Early prenatal diagnosis of hydrocephalus is an important way to prevent the birth of children with hydrocephalus. Since obvious hydrocephalus can be detected by B-ultrasound at 12-18 weeks of pregnancy, it is necessary to strengthen the application of B-ultrasound in prenatal diagnosis, terminate pregnancy early, prevent the birth of children with hydrocephalus, and reduce the birth rate of congenital hydrocephalus.

3. It is recommended to give birth at an appropriate age. Relevant data show that the incidence of hydrocephalus teratoma tends to increase with the age of the pregnant woman. Generally, the incidence rate is lowest in the 25-29 age group, but the difference is not significant. The incidence rate tends to increase after the age of 30. Therefore, advocating childbearing at an appropriate age has certain significance in preventing the occurrence of fetal hydrocephalus.

4Avoid radioactive contamination.

5. Avoid contact with harmful chemicals (especially those containing lead or benzene).

6 Avoid taking medications during pregnancy, including Western medicine and Chinese patent medicine, and pay special attention to avoid using Chinese patent medicine for traumatic injuries.

The above is an introduction on how to prevent the widening of the posterior horn of the right lateral ventricle of the fetus. After understanding it, we know that there are many reasons for such symptoms. If the mother can maintain a happy mood during pregnancy and maintain good living habits, such symptoms can be avoided to a large extent. In addition, I hope that many families preparing for pregnancy must do a prenatal physical examination before pregnancy, which can prevent the occurrence of many diseases to a large extent.
