Umbilical cord torsion What causes umbilical cord torsion?

What is umbilical cord torsion

Umbilical cord torsion refers to the situation where the intrauterine movement of the fetus causes the umbilical cord to appear spiral or cord-like.

Umbilical cord torsion is a rare type of umbilical cord abnormality. Fetal activity can make the normal umbilical cord spiral, that is, the umbilical cord twists along its longitudinal axis. Physiological twisting can reach 6-11 weeks. Excessive torsion of the umbilical cord becomes thinner and becomes cord-like necrosis near the fetal umbilicus, causing vascular occlusion or the presence of thrombus. The fetus may die due to interruption of blood transportation.

Umbilical cord torsion The reason is not yet clear.

Umbilical cord torsion is a sudden condition in the uterus. So far, medical science still cannot detect the signs early. The real cause of umbilical cord torsion has not yet been clearly identified in medicine. Some scholars believe that It may be related to the underdevelopment of the umbilical cord and local weakness of Watong's glue. Wharton's glue is weak, and the umbilical blood vessels twist along the longitudinal axis, and the blood vessels twist and narrow, blocking the umbilical blood flow, which can easily cause intrauterine distress and sudden death of the fetus. . Other scholars believe that the torsion of the umbilical cord is related to the maternal and childbirth conditions and the sex of the fetus. They believe that the abdominal wall of multiparous women is loose, which facilitates fetal movement. Male fetuses are more mobile and prone to torsion. There are also some scholars who believe that torsion occurs only after fetal death. Although the cause of umbilical cord torsion is not yet clear, by strengthening perinatal monitoring, abnormal changes in umbilical cord blood flow can be discovered and the fetal life can be saved as early as possible. Therefore, the cause of umbilical cord torsion is not yet clear.

Color ultrasound examination: Color ultrasound is simply a high-definition black and white B-ultrasound plus color Doppler. First, let’s talk about the ultrasound frequency shift diagnostic method, which is D-ultrasound. Four-dimensional color ultrasound can observe the growth and development of intrauterine fetuses from multiple directions and angles, providing accurate scientific basis for early diagnosis of fetal congenital surface malformations and congenital heart diseases. Therefore, umbilical cord torsion can be detected with color ultrasound.

Counting fetal movements: From the 28th week of pregnancy, it is necessary to pay attention to changes in fetal movements and measure fetal movements for one hour each morning, noon, and evening while lying on the left side. Once the number of fetal movements is found to be lower than normal, timely examination should be carried out to save the fetus.

Fetal heart rate monitor: If possible, buy a fetal heart rate monitor. You can listen to the fetal heart rate monitor at home every day to detect the condition of the child in the belly as early as possible.

Strengthen perinatal monitoring

Umbilical cord torsion is rare. If not discovered in time, fetal mortality is high and it is extremely harmful to perinatal babies. And there is still a lack of special means for diagnosing this disease. Therefore, once abnormalities are found during pregnancy, especially when early symptoms of umbilical cord torsion appear, perinatal monitoring should be strengthened.

Immediate caesarean section

The umbilical cord was twisted for 4 weeks, the prenatal examination was unremarkable, and the B-ultrasound did not show that the umbilical cord was wrapped around the neck. After admission, the fetal heartbeat was found to be slowing down, so emergency cesarean section was performed. survivor.

Therefore, in addition to clinical B-ultrasound examination, color Doppler examination must also be used. At the same time, it is extremely important to strengthen fetal heart rate monitoring for abnormalities after labor. If abnormalities are found, cesarean section should be performed in time to terminate the pregnancy.

Perform surgical evacuation

Some fetuses die due to interruption of blood transportation. In this case, surgical evacuation is required, and there is no need to preserve the fetus. A stillbirth in the uterine cavity is only harmful, so you should strive for early surgery. Abortion surgery is simple because the embryo is so small that it has stopped developing long ago. Antibacterial treatment is given after the operation, and you can wait 1 year before becoming pregnant again. This ensures that the uterus is restored.

Basic knowledge about umbilical cord torsion

< p> How to prevent umbilical cord torsion

Stay away from passive smoking

Pregnant mothers who smoke must quit during pregnancy. Although some pregnant mothers do not smoke, they must Stay away from "second-hand smoke", the degree of pollution it causes is no worse than smoking yourself. Medical research shows that women's regular smoking or passive smoking, especially during pregnancy, can lead to deformities in the development of the baby's maxillofacial area or oral cavity, which can lead to many dental problems and periodontal disease, making it difficult for the baby to have a good health from the beginning of life. Without healthy and strong teeth, it is difficult to maintain physical and mental health.

Bathing time should be moderate

When bathing every day, in addition to paying attention to the water temperature not being too high, the bathing time should not be too long. This is because this can easily make pregnant mothers feel tired, dizzy and cold. In particular, taking a sitz bath for too long can cause uterine congestion, which may cause miscarriage.

Keep a happy mood every day

Ensure adequate sleep for more than 8 hours a day and develop a good habit of taking a nap at noon. In order to reduce the anxiety caused by early pregnancy reactions, you can adjust the color of the room to green to help relieve nervousness. In this way, the pregnant mother's heartbeat can be slowed down, her breathing can be calmed, and her mind can be relaxed.

Pay attention to moderation in sexual life

Pregnant mothers have low sexual response due to morning sickness, and they also intentionally avoid it, for fear that it will be detrimental to the fetus. Husbands should be fully considerate of pregnant mothers. The placenta has not yet been fully formed at this time, and the amount of progesterone secreted is not high enough. This is the time when miscarriage is most likely to occur. Therefore, you should try to reduce the frequency of sexual intercourse as much as possible, and pay attention to gentle movements during occasional intercourse, especially pregnant mothers who have habitual miscarriages or have had miscarriages. Sexual intercourse should be avoided on full moon nights as it is very easy to cause miscarriage. If bleeding or abdominal pain occurs, stop sexual intercourse immediately.
