First‐trimester sonographic umbilical cord diameter and the growth of the human embryo

Abstract

ABSTRACT

Ultrasonic Measurement of Fetal Parameters for Estimation of Gestational Age in Korean Black Goats

“…In human fetus, umbilical cord diameter (r=0.78), crownrump length (r=0.75) and biparietal diameter (r=0.81) were significantly correlated with gestational age [6]. Similar with these human results, umbilical cord (r=0.7074) and vein (r=0.7892) diameter were also significantly correlated with gestational age in Korean black goat.…”

Sonographic umbilical vessel morphometry and perinatal outcome of fetuses with a lean umbilical cord

“…Of note, it has been reported that morphometric alterations of the umbilical cord in the first trimester of gestation are frequently seen in cases that subsequently develop preeclampsia or early fetal demise. 8 In conclusion, the present study shows that an association exists between the reduction of the umbilical vein cross-sectional area in late gestation and adverse neonatal outcome or fetal death. The temporal relationship between the sonographic changes in the umbilical cord and vessel areas and the occurrence of complications of pregnancy and adverse neonatal outcome remains to be explored.…”

“…[3][4][5][6][7][8] It has been demonstrated that a lean umbilical cord is associated with growth developmental disorders, 3 preeclampsia, 4 oligohydramnios, 3,7 and fetal distress during labor. 3,7 Correspondence to: F. Ghezzi A thin umbilical cord might be determined by a reduction of the amount of Wharton's jelly, as suggested by Schumann 1 and Hall, 2 by a reduction of the umbilical cord vessels' cross-sectional area, or by both.…”

Is there any relation between umbilical artery and vein diameter and estimated fetal weight in healthy pregnant women?

“…Studies have shown that starting from the first trimester there is an association between umbilical cord diameter and anthropometric parameters. In a study by Ghezzi et al [14], umbilical cord diameter, crown-rump length, and biparietal diameter were measured in 439 fetuses at between 8 and 15 weeks of gestation. They found that umbilical cord diameter increased steadily as gestation advanced, and a significant correlation was found between umbilical cord diameter and gestational age, umbilical cord diameter and crown-rump length, and umbilical cord diameter and biparietal diameter.…”
