Causes of widening of the intra-abdominal umbilical vein

Everyone knows that when the fetus is in the pregnant woman's belly, it is completely connected to the pregnant woman by the umbilical cord, and various nutrients are supplied to the fetus through the umbilical cord. The umbilical cord plays a vital role in the normal development of the fetus. When pregnant women undergo prenatal checkups, they will check whether the umbilical cord is in normal condition. If the umbilical vein appears to be widened, close observation is required.

Causes of widening of the intra-abdominal umbilical vein

There are many reasons for the localized dilatation of the abdominal segment of the umbilical vein, such as chronic fetal hypoxia or umbilical cord compression. If the fetal development indicators are normal, there is probably no problem. You need to pay attention to check whether the fetus has developmental or nutritional abnormalities and do fetal monitoring on time, but you still need to go to the hospital for specific examinations.

Precautions

1. Widening of the umbilical vein. Compression of the umbilical cord can cause widening of the umbilical vein. Chronic fetal hypoxia can also cause widening of the umbilical vein. It is recommended to go to the hospital for fetal heart monitoring. If the fetal heart monitoring is normal, pay close attention to fetal movement.

2. The inner diameter of the umbilical vein is slightly wide, and further examination is needed to rule out other malformations. The general inner diameter is within 1 cm. If it is slightly wider, timely and close follow-up and reexamination of the fetal heart condition are required. Have regular checkups, take some time to rest, avoid excessive stress, and keep a happy mood.

Function of the umbilical vein

1. The navel is the "bond" connecting the fetus and the mother. Generally, the umbilical cord contains a vein, two arteries, and is surrounded by gelatinous tissue. This is the only way for the mother to supply nutrition to the fetus and for the fetus to excrete waste. Metabolites in the fetus, such as urea, uric acid, creatinine, creatine, etc., can be sent into the mother's blood through the placenta and excreted from the body. The umbilical cord is a band-like organ connecting the fetus and the placenta. One end is connected to the fetal umbilical cord and the other end is attached to the fetal surface of the placenta.

2. The umbilical cord of a full-term fetus is 30-7ocm long and contains one umbilical vein and two umbilical arteries. It is surrounded by water-rich embryonic connective tissue called Wharton's jelly, which protects the umbilical cord blood vessels. The fetus exchanges nutrients and metabolic substances with the mother through the umbilical cord blood circulation. That is to say, the mother delivers nutrients and oxygen to the fetus through the umbilical vein, and the umbilical artery transports the fetus's waste and carbon dioxide back to the mother. When the umbilical cord is compressed and blood flow is blocked, it may endanger the life of the fetus.
