Selection: intrauterine fetal demise, without gross congenital malformations
A requirement is a reliable gestational age at birth.
Criteria for fetal growth restriction - one of the following:
(1) evident antenatal clinical diagnosis of fetal growth restriction (FGR)
(2) birth weight less than 3rd percentile for gestational age
(3) >= 5 of the following:
(3a) body weight less than 10th percentile at delivery or autopsy
(3b) brain weight less than 10th percentile
(3c) foot length less than 10th percentile
(3d) liver weight less than 10th percentile
(3e) placental weight less than 10th percentile
(3f) ratio of weight for brain to liver weight > 4
(3g) ratio of weight for placental to body weight > 90th percentile
(3h) pathologic features of placental insufficiency (vascular malperfusion)
(3i) antenatal history includes imaging studies consistent with fetal growth restriction
where:
• The criteria include an entry for birth weight less than the 10th percentile and a weight at autopsy less than the 10th percentile. Since this relates to IUFD, then there would be neither live birth nor a chance for the 2 to differ.
• "Evident antenatal clinical diagnosis of FGR" without criteria seems to lack objectivity.
