The umbilical coiling index

American Journal of Obstetrics and Gynecology, 1994
Our purpose was to objectively quantitate umbilical vascular coiling.In this prospective study the umbilical cords and delivery records of 100 consecutive liveborn neonates were studied. The umbilical coiling index of each cord was determined by dividing the total number of complete umbilical vascular coils by the umbilical cord length (in centimeters).

The umbilical coiling index in normal pregnancy

Journal of Maternal-Fetal and Neonatal Medicine, 2002
To provide reference values for the umbilical coiling index in uncomplicated pregnancy.Umbilical cords were collected from livebom singleton infants born after uncomplicated pregnancies. The umbilical coiling index (UCI) was calculated as the number of coils divided by the cord length in centimeters.

The umbilical coiling index and adverse perinatal outcome

International Journal of Gynecology & Obstetrics, 2006
AbstractObjective: Evaluation of the relationship between umbilical coiling index (UCI) and adverse perinatal outcome.Method: A prospective study was performed on 699 pregnant women who were 37–40 weeks. UCI was determined by dividing the total number of the complete vascular coiling by the total umbilical cord length in centimeters.
