Brief summary
Ultrasound measurement of cross sectional area of umbilical cord might offer advantage over Hadlock's formula for accurate estimation of actual birth weight at term gestation leading to prevention of large number of maternal and neonatal morbidity and mortality.
Detailed description
Umbilical cord is a vital structure of maternal-fetal life that can be used to evaluate pregnancy outcomes. In the past, sonographic investigations of the umbilical cord were limited to identification of the number of vessels and Doppler evaluation of the blood flow. Various formulas have developed to calculate Estimated Fetal Weight (EFW) using fetal biometry. While it is being accurate to a degree, they are associated with error especially with extreme birth weight. In this study using the ultrasound to look for a relation between the umbilical cord cross sectional area and estimated birth weight, as it's easy to use and readily available, comparing the estimated birth weight obtained by this method with that of Hadlock's formula measures at term gestation. Trying to prove that the umbilical cord area formula might gave advocacy for future usage for birth weight prediction.
