Intrauterine / fetal growth restriction (IUGR / FGR) is the most important cause of perinatal morbidity and mortality affecting normal pregnancies in approximately 7-15% or pregnancies complicated with hypertension in up to 30% of cases. Although "small" fetuses with intrauterine growth restriction are described in many ways, specialized literature defines it more commonly as a fetus with an estimated weight below the 10th percentile for its gestational age.
