[How I explore… intrauterine growth restriction].

Intrauterine growth restriction (IUGR) is a common obstetrical condition (10 % of all pregnancies). Its origin is most often vascular, but it may also be a symptom of another fetal pathology (infectious, genetic, syndromic). Screening may be complicated due to the low sensitivity of the clinical examination as well as ultrasound. However, IUGR exposes the newborn to increased perinatal morbidity and mortality. In addition, various studies show that children born with low birth weight have a higher incidence of metabolic disorders in the long term. If an IUGR is discovered, an etiological development and management strategy must be carried out in a multidisciplinary manner.
