Coiling characteristics of umbilical cords in breech vs. vertex presentation.

چکیده
OBJECTIVE To compare selected umbilical cord parameters, especially cord coiling, between breech and vertex presentations. METHODS We prospectively collected umbilical cords from uncomplicated breech and vertex obtained during elective term cesarean deliveries. We compared various cord parameters between the two groups as well as data regarding obstetric history and pregnancy outcome. RESULTS We evaluated 55 umbilical cords from breech and 55 from vertex deliveries. Umbilical cord length (56.93 cm vs. 63.95 cm, P=0.05), number of coils (5.1+/-0.4 vs. 11.7+/-0.6, P<0.0001) and umbilical cord index (UCI) (0.09 coils/cm vs. 0.18 coils/cm, P<0.0001) were all significantly lower for breech presentations and remained significant following multivariate analysis. CONCLUSION We document significant differences in umbilical coiling and the UCI between breech and vertex presentation. The precise reason for these differences is still unclear.

Gross patterns of umbilical cord coiling: correlations with placental histology and stillbirth.
INTRODUCTION The purpose of this study was to define gross patterns of umbilical cord hypercoiling and determine correlations with histological features in the placenta and/or perinatal outcomes such as stillbirth. METHODS Gross images of placentas with hypercoiled umbilical cords (>3 coils/10 cm) were assigned a major umbilical coiling pattern and the direction (right or left) of the coiling...
متن کاملAbnormal Umbilical Cord Coiling Index and Its Relation to Adverse Perinatal Outcome
Background: The umbilical cord is vital to the development, well being and survival of the fetus. A coil of the cord is defined as a complete 360 degree spiral course of umbilical vessels around Wharton’s jelly. Sonographically, the Umbilical Coiling Index (UCI) is defined as the reciprocal of the average distance between a pair of coils. Hypocoiled cords are those with UCI < 10 centile while h...

متن کاملDelivery of breech presentation infants at term. An analysis of 304 breech-deliveries.
304 breech presentation infants greater than or equal to 2.500 g were delivered at the University Women's Clinic, Kiel, between 1984 and 1987. Only 2 of the vaginally delivered infants died; both had severe malformations sonographically diagnosed prior to delivery. The umbilical cord arterial PH was found to be significantly (p less than 0.001) higher in infants delivered per Caesarean Section ...
