Sonographic evaluation of the umbilical cord coiling can be performed during routine foetal anatomic survey in the second trimester of pregnancy. Umbilical coiling index can be determined by dividing 1 by the intercoil distance in centimetres. Umbilical coiling index has been reported to be around 0.21 + 0.07 (standard deviation) coils per centimetre. Abnormal coiling in its two forms, hypercoiling and hypocoiling, have been reported to be more frequent in gestational diabetes and pre-eclampsia.
