Why do we cut the umbilical cord?
Why Do We Cut The Umbilical Cord. The umbilical cord is the fetal lifeline. It links the placenta feeding the baby to the womb/uterus and keeps the fetus alive. Cutting it marks life outside of mom. During natural childbirth, this cutting of the umbilical cord is done by the father (although sometimes another relative or friend is selected for ...
How common is 2 vessel cord?
However, some babies have just one artery and vein. This condition is known as a two-vessel cord diagnosis. Doctors also call this a single umbilical artery (SUA). According to Kaiser Permanente, an estimated 1 percent of pregnancies have a two-vessel cord.
What does 3vc mean on ultrasound?
three-vessel cordA normal umbilical cord has two arteries and one vein. This is known as a three-vessel cord. It is covered by a thick gelatinous substance known as Wharton's Jelly. The vein brings in oxygen and nutrients to the baby from the mother.
How serious is marginal cord insertion?
Pregnancies complicated by marginal cord insertion are at higher risk to develop low birth weight (AOR = 2.89, 95% CI: 1.23–6.80), preterm birth (AOR = 4.00, 95% CI: 1.44–11.14), and emergency cesarean delivery (AOR = 3.68, 95% CI: 1.03–13.81).
What causes a Hypercoiled umbilical cord?
Risk factors for hypercoiling were extremes of maternal age; and for non-coiling were obesity, gestational diabetes mellitus and pre-eclampsia. Hypercoiled and non-coiled cords were significantly associated with adverse perinatal outcomes and caesarean delivery.
Does 2 vessel cord mean Down syndrome?
There used to be a belief that a two-vessel cord signaled an increased risk of chromosomal abnormalities like Down syndrome, but that's actually not true — those would be more likely to be signaled by other symptoms, and your doc would look at other factors to diagnose something like that.
Can an umbilical cord be mistaken for a boy?
We tend to overpredict boys more often than girls. This can happen, for example, if the baby is developing slowly and the tubercle hasn't begun to point up or the umbilical cord is mistaken for a penis. While gender prediction is much more accurate during the 20-week ultrasound, there's still a chance it can be wrong.
Can you have a healthy baby with marginal cord insertion?
Only 7% of pregnancies have what is known as “Battledore cord insertion” or marginal cord insertion. The umbilical cord connects within 2 cm of the placenta's edge instead of near the center. Usually, this is not a problem—many women with this condition deliver healthy babies.
Do you deliver early with marginal cord insertion?
(This study looked at the association between marginal cord insertions and adverse outcomes in singleton births. The researchers concluded that marginal cord insertions increased the risk for preterm deliveries, low birth weights, and emergency C-sections.
Can marginal cord insertion fix itself?
The good news is that sometimes marginal cord insertion will correct itself over time. In a velamentous cord insertion (VCI), the umbilical blood vessels insert into the amniotic sac instead of the placenta. This type of abnormal cord insertion is less common, occurring in only .
What does a Hypocoiled umbilical cord mean?
What is hypocoiling of the cord? The term “hypocoiling of the cord” refers to abnormal decrease in the coiling of the umbilical cord. This is defined as UCI less than the 5th percentile for the gestational age of the fetus.
What does a uncoiled umbilical cord mean?
Non-coiled umbilical vessels may represent a pathologic developmental process that places the fetus at risk. Moreover, absence of the normal coiled umbilical configuration may result in a cord that is structurally less able to resist external compressive forces.
What are the abnormalities of umbilical cord?

Does EIF always mean Down syndrome?
Could an EIF mean the baby has Down syndrome? Some studies raised concerns about a small risk for Down syndrome with this ultrasound finding. However, most studies do not find a higher risk for Down syndrome when an EIF is the only ultrasound finding.
How can you tell if its a boy or girl by the placenta?
According to the theory, the placement of your developing placenta – which must be determined in a very precise way – can reveal your baby's sex. If your placenta is forming on the right side of your uterus, the baby is most likely a boy, the theory claims. If it's forming on the left side, it's probably a girl.
Should I worry about echogenic focus?
But echogenic intracardiac focus (EIF) is almost never something to worry about. It shows up as a bright spot on the heart in imaging, and it's thought to be a microcalcification on the heart muscle. EIF occurs in as many as 5 percent of all pregnancies.
Should I be worried about echogenic bowel?
One of the known reasons for echogenic bowel is an early bleed in the pregnancy (which you may not have been aware of). Echogenic bowel may be caused by the baby swallowing some blood in the amniotic fluid. This is not harmful to the baby. Echogenic bowel can be associated with cystic fibrosis.
What is the umbilical cord?
What Is an Umbilical Cord? Your baby’s umbilical cord is a tube-like structure that connects your baby to you via your placenta. The umbilical cord carries nutrients and oxygen from your placenta into your baby’s body, and then carries waste material out. The umbilical cord has two arteries and one vein.
How many arteries does the umbilical cord have?

The arteries are responsible for transporting your baby’s waste material, which are eventually disposed of through your kidneys. The umbilical cord’s arteries and veins are surrounded by a gelatin-like substance ...
How many women have umbilical cord cysts?
Umbilical cord cysts occur in about 3.4% of pregnancies. In and of themselves, they are usually not an issue. But they are known to occur with other congenital abnormalities such as trisomies of chromosomes (13 and 18), angiomyxoma of the cord, and imperforate anus .
What is the condition where the umbilical cord drops into the space between the baby and the cervix?
Umbilical Cord Prolapse. In this condition, the umbilical cord drops into the space between your baby’s body and the cervix prior to delivery. This may happen before birth or during labor.

For terms of location, the proximal part of an umbilical cord refers to the segment closest to the embryo or fetus in embryology and fetal medicine, and closest to the placenta in placental pathology, and opposite for the distal part, respectively.
How much blood flow through umbilical cord at 20 weeks?
The blood flow through the umbilical cord is approximately 35 ml / min at 20 weeks, and 240 ml / min at 40 weeks of gestation. Adapted to the weight of the fetus, this corresponds to 115 ml / min / kg at 20 weeks and 64 ml / min / kg at 40 weeks.
Why does the umbilical cord occlude after birth?
In absence of external interventions, the umbilical cord occludes physiologically shortly after birth, explained both by a swelling and collapse of Wharton's jelly in response to a reduction in temperature and by vasoconstriction of the blood vessels by smooth muscle contraction .
Where does the umbilical cord enter the fetus?
The umbilical cord enters the fetus via the abdomen, at the point which (after separation) will become the umbilicus (or navel). Within the fetus, the umbilical vein continues towards the transverse fissure of the liver, where it splits into two.

The umbilical cord is the connection between your baby and the placenta. A normal umbilical cord has two arteries and one vein. This is known as a three-vessel cord. It is covered by a thick gelatinous substance known as Wharton's Jelly.
What is velamentous insertion?
Velamentous Insertion. A velamentous insertion of the cord means that it inserts into the actual membranes rather than the center of the placenta. This leaves the vessels exposed in places, making it possible for them to become compressed as the baby gets bigger.
What is the purpose of the three vein cord?
It is covered by a thick gelatinous substance known as Wharton's Jelly. The vein brings in oxygen and nutrients to the baby from the mother. The arteries are used to transport waste away from the baby to the mother via the placenta.

The good news is that the vast majority of the time there are no complications with the umbilical cord. It is a fascinating structure that works with the placenta and baby.
Overview
In placental mammals, the umbilical cord (also called the navel string, birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich bl…
Structure and development
The umbilical cord develops from and contains remnants of the yolk sac and allantois. It forms by the fifth week of development, replacing the yolk sac as the source of nutrients for the embryo. The cord is not directly connected to the mother's circulatory system, but instead joins the placenta, which transfers materials to and from the maternal blood without allowing direct mixing. The length of the umbilical cord is approximately equal to the crown-rump length of the fetus thro…
Function
The umbilical cord enters the fetus via the abdomen, at the point which (after separation) will become the umbilicus (or navel). Within the fetus, the umbilical vein continues towards the transverse fissure of the liver, where it splits into two. One of these branches joins with the hepatic portal vein (connecting to its left branch), which carries blood into the liver. The second branch (known as the ductus venosus) bypasses the liver and flows into the inferior vena cava, which ca…
Clinical significance
A number of abnormalities can affect the umbilical cord, which can cause problems that affect both mother and child:
• Umbilical cord compression can result from, for example, entanglement of the cord, a knot in the cord, or a nuchal cord, (which is the wrapping of the umbilical cord around the fetal neck) but these conditions do not always cause obstruction of fetal circulation.
The umbilical cord in other animals
The umbilical cord in some mammals, including cattle and sheep, contains two distinct umbilical veins. There is only one umbilical vein in the human umbilical cord.
In some animals, the mother will gnaw through the cord, thus separating the placenta from the offspring. The cord along with the placenta is often eaten by the mother, to provide nourishment and to dispose of tissues that would otherwise attract scavengers or predators. In chimpanzees, …
Other uses for the term "umbilical cord"
The term "umbilical cord" or just "umbilical" has also come to be used for other cords with similar functions, such as the hose connecting surface-supplied divers to their surface supply of air and/or heating, or space-suited astronauts to their spacecraft.
