Moms are no stranger to the umbilical cord, and the umbilical cord is directly related to the safety and health of the fetus.The umbilical cord is connected to the mother and the fetus, and its main role is to transport nutrients and metabolites for the baby.However, there are many problems with umbilical cords. Whether it is too long, or the fetal size is small, or the fetal movement is too frequent or the amniotic fluid can cause the umbilical cord to wrap.Caused the fetus in the palace.The most common umbilical cord abnormalities are the following types. Let’s take a look at it.
1. The umbilical cord is too long or too short
In health, the umbilical cord of the full moon fetus is about 55cm.The umbilical cord is too long greater than 70cm. In this case, the umbilical cord winding or knotting problem is prone to occur. The umbilical cord prolapse may occur.It may cause the fetus to decrease difficulty, or the umbilical cord is too tight to cause the fetal distress, which can cause early peeling of the placenta.
2. Umbilical cord drooping
After the fetal membrane ruptured, the umbilical cord had fallen off before the fetus was born.This is a relatively serious complications. No timely rescue may cause fetal death due to blood flow blocking.
3. umbilical cord entanglement
The incidence of umbilical cord windings is the highest. Most pregnant women will have this situation, as well as umbilical cord around the body or around the limbs.If the entanglement is too tight, it can easily cause the fetal distress, especially during the childbirth, the umbilical cord is insufficient after the fetal head decreases. The tightening of the umbilical cord can block the blood circulation, or cause the fetal head to decrease difficulty, prolong the birth and premature placenta.
4, umbilical cord first exposure
The umbilical cord is first exposed in the umbilical cord prolapse. Because the fetal membrane is not broken, the umbilical cord is first exposed below the tire, and the pulp is prone to lust after the fetal membrane is ruptured.
5, umbilical cord knot
The umbilical cord knot is divided into pseudo and true. The former is caused by the different lengths of the umbilical blood vessels and umbilical cord. The blood vessels in the umbilical cord are distorted, which will hardly affect the safety of the fetus;At first it was the umbilical cord around the body, and then the fetus was worn out of the umbilical cord around the body, causing the umbilical cord knot.If the umbilical cord is tightened, the blood circulation can be blocked, which can easily lead to suffocation in the palace, and even die during childbirth.
6, umbilical cord reversing
The umbilical cord twist is also rotating and twisting in a certain direction. Generally, rotation in the opposite direction can return to normal.Umbilical cord reversing is closely related to fetal activity. Most fetuses will have umbilical cord twisting. However, excessive reversal may interrupt blood circulation and raise the fetal mortality.
7, single umbilical artery
Generally, there are umbilical veins and umbilical arteries in the umbilical cord. The former has only 1 and the latter has 2.If the embryo develops abnormal, there is only one umbilical arteries, which is known as a single umbilical arteries in medicine.When a single umbilical arteries can affect the blood supply of fetal fetus, it is not enough to obtain enough blood, nutrition and oxygen supply. Therefore, it is easy to cause premature fetal birth, which makes the fetus grow slowly, which can cause hypoxia in the fetus in severe cases.
8, umbilical cord sail -like adhesion
Generally, the umbilical cord is attached to the middle of the placenta or on one side. If the umbilical cord grows on the placental membrane outside the placenta, the umbilical blood vessels will be exposed in the uterine cavity. This is the so -called umbilical cord -shaped adhesion, which can easily appear on the twins.During childbirth, the umbilical cord is pulled, or the umbilical cord attachment occurs at the attachment of the umbilical cord during delivery, which will cause severe bleeding.
Pregnant women should regularly do B -ultrasound to obtain umbilical cord images clearly, and understand whether there is a neck tenta caused by the umbilical cord neck.In some cases, it is necessary to do a color Doppler examination. It can diagnose a variety of umbilical cord abnormalities, and can distinguish the umbilical cord around the neck or neck.
