Case Discussion

The nuchal cord is a condition resulting from the wrapping of one or more loops of the umbilical cord around the fetal neck for equal or more than 360 degrees. It may be associated with a long umbilical cord and polyhydramnios.

It may be associated with many complications, like intrauterine growth restrictions (IUGR), fetal developmental delay, decreased amniotic fluid volume, formation of a cord knot, decreased fetal movement, neonatal anemia, hypovolemia and metabolic acidosis and in rare situations intrauterine fetal death (IUD).
