Management of fetal macrosomia is based on a suspicion of macrosomia (no certainty before birth). This management is an artificial induction of labour for an earlier delivery and therefore a lower fetal weight gain. Several studies have already shown that ultrasound performed during the third trimester of pregnancy was not a perfect tool for this screening.

The aim of the study is to describe management of women whose child is macrosomal but has not been screened g using ultrasound during the third trimester of pregnancy.
