A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck. [1] Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and bleeding in the whites of the eye. [1] Complications can include meconium, respiratory distress, anemia, and stillbirth. [1]
Occasionally, during pregnancy, there is a single umbilical artery (SUA) present in the umbilical cord, as opposed to the usual two. [1] This is sometimes also called a two-vessel umbilical cord, or two-vessel cord. Approximately, this affects between 1 in 100 and 1 in 500 pregnancies, making it the most common umbilical abnormality.
Nuchal cord, when the umbilical cord is (tightly) around the neck of the fetus [2] Entanglement of the cord [2] Knot in the cord [2] Cord prolapse, where the umbilical cord exits the birth canal before the baby, which can cause cord compression. [3] As a complication of oligohydramnios in which there is insufficient amniotic fluid
Screening for Down syndrome by a combination of maternal age and thickness of nuchal translucency in the fetus at 11–14 weeks of gestation was introduced in the 1990s. [7] This method identifies about 75% of affected fetuses while screening about 5% of pregnancies. Natural fetal loss after positive diagnosis at 12 weeks is about 30%. [6]
Umbilical cord compression can result from, for example, entanglement of the cord, [16] a knot in the cord, [16] or a nuchal cord, [16] (which is the wrapping of the umbilical cord around the fetal neck) [17] but these conditions do not always cause obstruction of fetal circulation.

Cord check. The presence of an umbilical cord (nuchal cord) is checked to determine if it is around the baby's neck. [22] [24] If it is present, an index finger is used to attempt to pull it over the baby's head. [22] [24] If this cannot be done, the cord is clamped/tied in two places. Then the cord is carefully cut, avoiding injury to the baby ...
Studies show that increased levels of hyperphosphorylated tau are associated with worse cognitive symptoms of Alzheimer’s. Because amyloid-beta tends to arrive on the scene earlier than NFTs ...
A hyperactive foetus should be evaluated with ultrasound to rule out cord entanglement. Cord entanglement – The umbilical cord can wrap around an extremity, the body or the neck of the foetus. When the cord is wrapped around the neck of the fetus, it is called a nuchal cord. These entanglements can cause constriction of blood flow to the fetus.
