Le contrôle de qualité en échographie prénatale : intérêt de la biométrie

Objective We examined the outcomes of pregnancies in which the fetal head circumference (HC) was below the 5 th centile at the routine second-trimester scan. Materials and MethodsWe retrospectively analysed outcomes of 18 377 women according to HC Z scores at secondtrimester ultrasound examination between 2001 and 2008. We collected all major malformations, intrauterine deaths and other abnormal outcomes.Results Six hundred seventy-four fetuses (3.7%) had an HC below the 5 th centile. Twenty-one major malformations were noted, consisting mainly of neurological abnormalities (3.1%). There were seven intra uterine fetal death (1.3%). Of all the fetuses, 26% were lost to follow-up. Outcome and neurological development was normal in 467 cases, based on neonatal examination and/or parent or general practitioner reports. Major abnormalities were noted in respectively 26.2%, 3.0% and 1.1% of fetuses with Z scores < À2.5, -2.5 to À2.0, and À2 to À1.645, compared with 0.3% of fetuses with normal HC (p < 10 -4 ).Conclusion A head circumference below the 5 th centile at second-trimester scan is associated with various abnormalities, especially neurological disorders. The outcome was worse when the HC was smaller. An HC Z score below À2.5 was strongly associated with neurological and chromosomal abnormalities. Conversely, an HC Z score below À1.645 but above À2, excluding cases with prenatally diagnosed malformations, seems to be reassuring for favorable neonatal outcome.
