A single entanglement of the umbilical cord around the neck of the fetus

Однократное обвитие пуповины вокруг шеи плодаOften when carrying out ultrasound during pregnancy, the woman hears from the doctor that conclusion, as a single entanglement of the umbilical cord around the neck of the fetus. This fact causes panic in almost all expectant mothers who are faced with such a situation. Try to understand and figure out: just how scary this kind of phenomenon and what can be dangerous to the health of the baby once the umbilical cord entanglement around the neck.

What causes entanglement?

First we need to say that such phenomenon may occur and disappear on their own. It is because doctors are in no hurry to make any conclusions, and in most cases take a wait-and-see tactics. Generally, if the entanglement was discovered about the middle of gestation, then a second ultrasound is carried out prior to delivery, 37 weeks of pregnancy.

As for the causes of a single entanglement of the umbilical cord, usually experts name the following factors leading to this:

  • umbilical cord length is more than 70 cm;
  • the presence of a large amount of amniotic fluid – polyhydramnios;
  • oxygen starvation of the fetus — hypoxia.

So, when the baby polyhydramnios there is a large space for movements, which rarely increases the likelihood of entanglement of umbilical cord not only around the body and neck.

As for hypoxia, it is often regarded as a provoking factor, i.e. an insufficient supply of oxygen to the fetus through the umbilical cord can lead to an increase in his physical activity. Ultimately, the fruit just falls into one of the loops of the umbilical cord.

What to do with a single entanglement of the umbilical cord around the neck of the fetus?

According to statistics, only about 10 % of cases of this kind the phenomenon leads to complications. It is because the expectant mother is not necessary to worry and be nervous about it. Moreover, the excitement of the mother may be transmitted to the fetus, which will only aggravate the situation.

As for doctors, then, as mentioned above, if available on the neck loop squeezes the fruit that physicians prefer to use a wait-and-see tactics, and that means waiting almost until delivery.

To determine the status of the fetus in a single cord entanglement his neck may be appointed cardiotocography (CTG) and doplerometriya. The first study involves the registration of cardiac contractions of a baby, and using a second state determine the intensity of blood flow in the vessels located in the umbilical cord.

What are the dangers of this phenomenon?

Once loosely the entanglement of the umbilical cord, as a rule, does not pose any danger to the health and development of the fetus. During pregnancy this condition may occur repeatedly and independently disappear, which prove conducted during pregnancy ultrasound.

As a rule, the danger to the health of the future child is a double tight entanglement. When such a phenomenon is the development of oxygen starvation. This violation negatively affects the processes of intrauterine development of the fetus and on the development of brain structures in particular.

The degree of negative impact depends on the duration of oxygen starvation of the fetus.

It is also worth noting that a strong tension of the umbilical cord, in view of shortening its overall length because of entanglement, often results in premature detachment of the placenta, that requires intervention of doctors.

Thus, as can be seen from this article, a single entanglement of the umbilical cord of the fetus around his neck should not cause concern to the expectant mother, because in no way affects its development.
