Sonographic evaluation of umbilical cord insertion with umbilical coiling index

Sonographic evaluation of umbilical cord insertion with umbilical coiling index Purpose The aim of this study was to investigate the association between umbilical cord hypocoiling and abnormal placental insertion of the umbilical cord. Methods Umbilical coiling was measured by sonography in 253 pregnant women in their second or third trimester. An umbilical coiling index, defined here as the reciprocal of the length of 1 umbilical vascular coil, of less than 0.1 was considered hypocoiled. The distance from the placental edge to the insertion of the umbilical cord was measured after delivery, and the results were used to classify cord insertion as normal, marginal, or velamentous. Results Cord insertion was abnormal in 66.7% of the fetuses with umbilical hypocoiling but in only 1.3% of those whose coiling index was ≥ 0.1 (p < 0.05). Conclusions Hypocoiling of the umbilical cord was highly associated with abnormal cord insertion. The presence of a hypocoiled umbilical cord may indicate the presence of abnormal cord insertion and thus may be useful for obstetric management. © 1999 John Wiley & Sons, Inc.
