[Intrauterine growth retardation (IUGR) vs small for gestational age fetus (SGA). Diagnostic aspects].

Fetal growth deficiency and low birthweight requires an accurate assessment and may be divided into two groups: 1. Intrauterine growth retardation (IUGR) which is strongly associated with a fetal structural malformation, infections (TORCH) and utreoplacental dysfunction considered to be the most common cause. 2. Genetically, constitutionally small baby (SGA) classified as a well-nourished, healthy and short baby. Taking into account clinical data, medical history, health state of a patient, serial ultrasound growth scan, Doppler ultrasound, cardiotocography and enzymatic monitoring may proved to be useful to differentiate between these two problems.
