What is considered to be a normal umbilical cord?
Normal umbilical cord that connects the fetus with the placenta has two arteries and one vein. The vein carries oxygenated blood and nutrients from the mother to the fetus and arteries take the waste from the fetus to the mother to exclude from the body. Three blood vessels in a normal umbilical cord are separated and padded with a whirl jelly, a fungal tissue. Doctors often use ultrasonic technology to detect complications of umbilical cord during pregnancy. The abnormal cord can be too long, too short or the missing artery to name some of the most common complications.
The typical umbilical cord is about five weeks after conception and grows up to about 28 weeks of pregnancy, at this point the length of 22-24 inches (55.9-61 cm) should be. The diameter of the normal umbilical cord is usually about 0.4-0.8 inches (1-2 cm). A cord that is unusually short, for example 12 inches (30.5 cm) or less, may result in a small child or fetus during the deliver, and this may indicate a genetic problem. Umbilical cord that measures more than 27 inches (68.6 cm), may result in entanglement into the womb and may indicate that the fetus is hyperactive because the cord tends to stretch as the child moves.
Another common aspect of a normal umbilical cord is the presence of three vessels, the other is the vein that brings the fetus of nutrients and blood. Two more blood vessels are arteries that take the waste from the fetus after oxygenated blood circulates through its body. Although the average cord has two arteries, some have only one, which may not cause a problem. However, this may sometimes indicate the presence of chromosomal abnormality or congenital defects. In addition, complications of umbilical cord are observed in dead births, and therefore most doctors offer deep testing during pregnancy with an abnormal cord.
In most pregnancies, the umbilical cord is attached to the center of the placenta, but instead it could connect to the fertile membranes, so the blood vessels remain exposed. This makes themProbably a rupture because they are not protected by WHARON jelly, and the result is that the child suffers from low birth weight, premature delivery or dead birth. Another problem related to the location of the cord is Vasa Previa, in which the blood vessels pass through the cervix just below the fruit and leave them vulnerable damage when the cervix expands. This can be prevented when the problem is detected at the beginning of pregnancy, and therefore doctors often perform several tests when they do not see a normal umbilical cord.
