Does high SD have any effect on the fetus?

Many pregnant women have a high SD. There are many reasons for this, it may be caused by the umbilical cord around the neck or the umbilical cord is too short. When this happens, it will have a certain impact on the fetus in the pregnant woman's belly, such as affecting physical development. If the situation is serious, it may also affect the life safety of the fetus. So, does a high SD have a big impact on the fetus? Let's introduce it below.

What are the hazards of high SD value to the fetus?

If the SD value is high, it is very harmful to the fetus. The fetus may suffer from developmental delay in the uterus, fetal reserve or fetal maldevelopment, the placenta may not increase, and the vascular resistance may not decrease. Clinically, if the SD value does not decrease according to a regular pattern, or if it increases, it means that the fetus is maldeveloped. Because the umbilical cord is wrapped around the neck, fetal movement should be observed frequently, and if there is any abnormality, you must seek medical attention in time.

Causes of high umbilical artery SD

There are many reasons for the high umbilical artery SD, so when dealing with it, it is necessary to find out the cause and do targeted treatment. Fetal malformation will cause a high SD value. Congenital fetal diseases are closely related to the resistance of the umbilical artery, so further B-ultrasound examination is necessary.

Abnormalities in the umbilical cord can also cause high SD values, such as the umbilical cord being too long or too short, or the umbilical cord being entangled. Abnormalities in the blood flow impedance index may also occur. If the SD value is higher than normal and the umbilical cord is wrapped around the neck, close observation must be carried out according to the pregnancy cycle.

What are the hazards of a high SD value to the fetus? During pregnancy, the fetus may be in various situations. If the SD value is high, the development of the fetus will be greatly harmed, and fetal maldevelopment may occur. The reason for the high SD value of the umbilical artery may be due to fetal malformation or abnormalities in the umbilical cord. Close observation should be done.
