At 36 weeks of pregnancy, which is approximately 9 months, it is close to full-term gestation. If an ultrasound reveals that the umbilical cord is wrapped around the neck twice, it often indicates the presence of a W-shaped notch behind the neck. Having the umbilical cord wrapped around the neck twice is a normal physiological occurrence and does not affect the growth and development of the fetus. Many pregnant women, upon hearing about the umbilical cord around the neck, fear it might affect fetal growth and development or cause ischemia or hypoxia, and thus want to correct it through various methods. Firstly, it is unnecessary to correct the umbilical cord around the neck as it is a physiological change. Secondly, there is no known method to correct this condition; neither dietary activities nor any other methods can intervene with the umbilical cord being wrapped around the neck. Therefore, there is no need, nor is there a way, to intervene with the umbilical cord wrapping; it is sufficient to simply observe and wait.

How to prevent umbilical cord entanglement in late pregnancy

There are no effective prevention methods for nuchal cord, which is the most common form of umbilical cord entanglement where the cord wraps around the fetus's neck, limbs, or trunk. Nuchal cord occurs in 90% of these cases, frequently involving the cord wrapping around the neck once. This phenomenon can be observed in 20% of deliveries and is associated with factors such as an overly long umbilical cord, a small fetus, excessive amniotic fluid, and frequent fetal movements. An excessively long umbilical cord is mostly a physiological occurrence since the cord floats in the amniotic fluid and its actual length cannot be accurately measured, with no effective methods to prevent its occurrence. Excessive amniotic fluid and a small fetus are linked to certain pregnancy complications, such as diabetes-induced polyhydramnios and restricted fetal growth. Actively controlling blood sugar during pregnancy can prevent such issues. Frequent fetal movements are physiological for some pregnant women. Women who experience more frequent fetal movements throughout pregnancy are likely to encounter nuchal cord. Clinically, nuchal cord does not require special management unless it leads to obstructions in fetal descent, fetal distress, or variations in fetal heart rate. It does not impact delivery or fetal development.

Is it dangerous for the umbilical cord to be wrapped around the neck during the mid-stage of pregnancy?

During a mid-pregnancy ultrasound, it is sometimes indicated by the presence of a U-shaped or W-shaped notch behind the fetus's neck that the fetus may have the umbilical cord wrapped around its neck. During pregnancy, it is perfectly normal for the umbilical cord to wrap around the neck, and it generally does not affect the fetus or pose any danger. The length of the umbilical cord during pregnancy is approximately 30 to 80 centimeters, which is quite long relative to the size of the uterine cavity. Hence, many umbilical cords have excess length that can wrap around the neck or limbs of the fetus, leading to the umbilical cord being coiled around the neck or limbs. However, current research indicates that whether the umbilical cord is wrapped around the neck or limbs once or twice, it does not affect the fetus. It does not cause intrauterine hypoxia or affect the growth and development of the fetus, nor does it influence the mode of delivery. A natural childbirth can still be an entirely viable option.

The difference between U-shaped and W-shaped nuchal cords.

During pregnancy, through ultrasound examination, if echoes of the umbilical cord are found around the fetus’s neck in U-shaped or W-shaped patterns, this indicates the presence of nuchal cord. The difference between U-shape and W-shape primarily lies in the number of wraps around the neck. A U-shaped notch indicates the umbilical cord is wrapped around the neck once; a W-shape indicates it is wrapped twice. When nuchal cord is present, there is no need to be overly anxious; regular prenatal check-ups can be conducted at the hospital to monitor the development of the nuchal cord and the safety of the fetus inside the uterus.

Umbilical cord around the neck ultrasound manifestations

The impact of umbilical cord entanglement on the fetus is quite significant. If the entanglement is excessive and tight, it can lead to fetal hypoxia. Generally, fetuses with the umbilical cord wrapped around the neck once or draped on the neck do not show clinical symptoms. However, if the entanglement is tight, it can jeopardize fetal health. During an ultrasound examination, echoes can be seen on the fetus's neck where the umbilical cord is wrapped, and distinct pressure marks may appear on the skin. A single wrap around the neck appears as a U-shape, two wraps appear as a W-shape, and three wraps as a serrated shape.
