What causes fetal neck twisting?

Fetal umbilical cord around the neck means that the umbilical cord connecting the fetus to the mother is wrapped around the fetus' neck, which is very likely to cause the fetus to suffer from suffocation. Therefore, pregnant women must pay special attention to whether the fetus has the umbilical cord wrapped around the neck during prenatal checkups. If found, special situations must be handled separately. So, what causes the fetal umbilical cord to wrap around the neck?

What causes the fetal umbilical cord to wrap around the neck?

Umbilical cord around the neck is a common condition during childbirth. It is generally believed that this is related to the umbilical cord being too long and the fetal movements being frequent. The fetus will often move around in the pregnant mother's body, rolling and turning in the small space of the uterus, and each fetus has different characteristics. Some fetuses have relatively gentle movements, while some fetuses have strong movements. They like to exercise and will move, play games, move their arms, stretch their legs, and turn around in the uterus. At this time, the umbilical cord may be entangled.

Umbilical cord around the neck is a high-risk pregnancy, which can cause confusion in the fetal uterine cavity at any time and anywhere. If the umbilical cord of the fetus has several entanglements in the late pregnancy, it is very dangerous for the fetus. Tight entanglements can affect the flow of umbilical cord blood, thereby affecting the metabolism of oxygen and carbon dioxide in the fetus, causing the fetus to have a slow heart rate. In severe cases, the fetus may suffer from insufficient oxygen and even fetal death. The impact of fetal umbilical cord coiling on the fetus is related to the number and tightness of the coiling, the length of the fetal umbilical cord, and the amniotic fluid flow. It is also related to whether you are giving birth. After delivery, if the fetus's head is in a downward position during childbirth, the umbilical cord of the fetus, which was originally coiled loosely, will gradually tighten.

Generally speaking, for fetuses with the umbilical cord entangled or around their necks, clinical symptoms are not likely to occur because the degree of entanglement and compression of the umbilical cord is mild. This type of entanglement does not pose a great risk to the mother and child, and the mother can still give birth successfully vaginally. Even if the umbilical cord is around the neck, because the fetal head is less active, as long as the umbilical cord is not strangled, it will generally not harm the health of the fetus. During pregnancy, if the umbilical cord is found to be entangled, pregnant women do not need to worry too much as long as the fetus is still moving. However, for fetuses with a large number of coils and severe compression, the umbilical cord may be too short due to the coiling of the fetal umbilical cord. If the coiling is too tight, it will affect the umbilical cord blood flow, which will first affect the fetal oxygen and carbon dioxide metabolism, causing the fetus to have a slow heartbeat. In severe cases, fetal hypoxia may occur, or even fetal death, which is relatively difficult and complicated to deal with.
