Association of Fetal Abdominal–Head Circumference Size Difference With Shoulder Dystocia: A Multicenter Study
Objective This study aims to determine if shoulder dystocia is associated with a difference in the fetal abdominal (AC) to head circumference (HC) of 50 mm or more noted on antenatal ultrasound. Study Design A multicenter matched case-control study was performed comparing women who had shoulder dystocia to controls who did not.

متن کاملUltrasonographic normogram of fetal kidney circumference and fetal abdominal circumference ratio for early prenatal diagnosis.
Serial ultrasound scans were done in 300 fetuses between 16 to 24 weeks of gestation to establish the normogram of fetal kidney circumference (FKC) and fetal abdominal circumference (FAC) ratio (FKC/FAC). Of 300 fetuses, 150 fetuses were in the high risk group for fetal malformation and 150 patients were in the control group. The value of FKC/FAC varied from 0.27 to 0.30 from 16 to 24 weeks of ...
متن کاملMid-arm circumference and mid-arm/head circumference ratio in term newborns.
CONTEXT Mid-arm circumference of the newborn is strongly associated with birth weight and is a very good indicator of low and insufficient birth weight. However, there are few Brazilian studies on the relationship between mid-arm and head circumferences and, thus, this does not form part of the routine evaluation for newborns. OBJECTIVES To establish the mid-arm circumference and mid-arm/head...
متن کاملFetal biparietal diameter, head circumference, abdominal circumference and femur length. A comparison by race and sex.
Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) were compared by race and sex in 5,405 ultrasound examinations done on 2,831 women. Black fetuses had significantly longer FL than white fetuses; male fetuses had larger BPD, HC and AC than females. The differences in BPD, HC and AC correlated with the different birth weights observed between ...
