Presentation
The patient had a previous history of polyhydramnios and presented for a routine third-trimester ultrasound examination.
Patient Data
Color Doppler ultrasound images show wrapped the umbilical cord around the fetal neck in multiple turns. A normal upper limit of amniotic fluid is noted (not shown in these images of the engaged fetus).
No other anomalies could be detected.
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).
