The umbilical coiling index, a review of the literature

Journal of Maternal-Fetal and Neonatal Medicine, 2005
Our aim was to review the literature on umbilical cord coiling. Relevant articles in English published between 1966 and 2003 were retrieved by a Medline search and cross-referencing. The normal umbilical cord coiling index (UCI) is 0.17 (+/- 0.009) spirals completed per cm. Abnormal cord coiling, i.e.

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).

Umbilical Coiling Index in Normal and Complicated Pregnancies

Obstetrics & Gynecology, 2006
To estimate the relation between undercoiling and overcoiling of the umbilical cord and adverse pregnancy outcome.Umbilical cords and hospital records of 885 patients were studied in a cross-sectional study design. The umbilical coiling index was determined as the number of complete coils divided by the length of the cord in centimeters, blinded for ...
