Macrosomia is associated with an increased risk of several complications, particularly maternal and/or fetal trauma during birth and neonatal hypoglycemia and respiratory problems. Fetal macrosomia has been defined to include birth weight greater than 4000 g or greater than 4500 g. [ 1] Macrosomia may place the mother and fetus or neonate at risk for adverse outcomes. Above. The fetal abdominal circumference is the single most important measurement to make in late pregnancy. 33 A macrosomic fetus will have increased AC relative to gestational age, and an asymmetrically growth-retarded fetus will have diminished AC measurements. Fetuses with larger abdominal circumferences on antenatal ultrasounds are more likely to be macrosomic with birth weight >4000 grams (OR 2.496, p < 0.0001). Increasing fetal AC is predictive of primary cesarean delivery (OR 1.486, p=0.0023). The ratio was above the 95th centile limit in 22 (71%) of these fetuses and evidence is presented to suggest that the H/A circumference ratio can be used to distinguish between symmetrical and asymmetrical growth retardation. So that being said, if I were given a report of my boy having a 80% head and a 50% abdominal readings, I won't think twice. Create an account or log in to participate.

This topic covers fetal age and growth assessment for the second and third trimester (14 -40 weeks gestation). Mean gestational age was 31 weeks. The proportion of AC to HC difference of 50 mm was significantly higher in shoulder dystocia cases (8%) than controls (1%, p = 0.002).
