What is the consequence of an abnormal umbilical cord insertion?
Any abnormal cord insertion, including marginal cord insertion, can potentially result in placental development problems which can impact fetal development and growth. Marginal cord insertion can restrict or reduce the blood flow and circulation to the fetus during pregnancy.
What are the abnormalities associated with short or long umbilical cords?
Complications associated with long or short umbilical cord may explain this enigma. Excessively short cords have been associated with a delay in second stage of labor, irregular fetal heart rate, placental abruption, rupture of umbilical cord, inversion of uterus, birth asphyxia, and cord herniation.
What does an abnormal umbilical cord mean?
A number of abnormalities can affect the umbilical cord. The cord may be too long or too short. It may connect improperly to the placenta or become knotted or compressed. Cord abnormalities can lead to problems during pregnancy or during labor and delivery.
What are the abnormalities of umbilical cord?
Fetal anomalies most commonly associated with single umbilical artery include several anomalies like ventricular septal defects, hydronephrosis, cleft lip, ventral wall defects, esophageal atresia, spina bifida, hydrocephaly, holoprosencephaly, diaphragmatic hernia, cystic hygromas, and polydactyly or syndactyly.
When does umbilical cord develop?
The umbilical cord begins to form at 5weeks after conception. It becomes progressively longer until 28 weeks of pregnancy, reaching an average length of 22 to 24 inches (1). As the cord gets longer, it generally coils around itself. The cord contains three blood vessels: two arteries and one vein.
When should I be concerned about the umbilical cord?
Signs of a problem Much like a scab, the cord stump might bleed a little when it falls off. However, contact your baby’s doctor if the umbilical area oozes pus, the surrounding skin becomes red and swollen, or the area develops a pink moist bump. These could be signs of an umbilical cord infection.
What trimester does the umbilical cord develop?
The umbilical cord attaches to the baby at the abdomen and to the mother at the placenta. The cord forms during the fifth week of gestation (seventh week of pregnancy).
What does the umbilical cord develop from?
When an egg is fertilized, it divides into two components — one becomes the embryo, which develops into the fetus, and the other becomes the placenta, which grows along the lining of the uterus. The umbilical cord develops from embryonic tissue and will grow about 60 centimetres long.
Is single umbilical artery harmful for the baby?
Even with reassurances from the doctor that it was reasonably common and most babies have no impact as a result when having a Single Umbilical Artery pregnancy, your mind still spins and the fears seep in. Most babies are fine, but 25% could have heart or kidney defects.
What does umbilical cord occlusion mean?
Umbilical Cord Occlusion. Blockage of blood flow in the umbilical vessels. (NCI Thesaurus)
How many vessels in umbilical cord?
The umbilical cord is made up of three blood vessels: two smaller arteries which carry blood to the placenta and a larger vein which returns blood to the fetus.
What is a straight umbilical cord?
Straight Umbilical Cord. An abnormality that occurs in approximately 5% of all pregnancies, in which a fetus’s umbilical cord appears to be straight rather than coiled. Research shows that there is an increased risk of fetal abnormalities and/or stillbirth when a straight umbilical cord is present.
