Association of Umbilical Cord Coiling and Medical Disorders of Pregnancy: a Cross-Sectional Study.

The coiling of the umbilical vessels develops by about 28 days post-conception and is present in about 95% of foetuses by around nine weeks of conception. Umbilical coiling (UC) is associated with many maternal and fetal outcomes. The present study attempts to assess any associations between medical disorders of pregnancy with umbilical cord coiling.
