NAZER H, Julio et al. RESTRICCIÓN DEL CRECIMIENTO INTRAUTERINO COMO FACTOR DE RIESGO PARA MALFORMACIONES CONGÉNITAS. Rev. chil. obstet. ginecol. [online]. 2009, vol.74, n.6, pp.366-371. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262009000600008.

Background: Fetal growth restriction (FGR) is the result of anomalies that prevent the normal development of the fetus, it is present in about the 5% of births. Objectives: To estímate the frequency of FGR in the Clini-cal Hospital of the University of Chile. To estímate the congenital malformation prevalence rate at birth and compare it among small (SGE), adequate (AGE) and large (LGE) newborns according their gestational age. Methods: All live births and stillbirths included in the ECLAMC (Estudio Colaborativo Latino Americano de Malformaciones Congénitas) registered from January 1997 and December 2008 were considered. Newborns with congenital malformations that modified per se the size of the child, like hydrocephaly anencephaly and hydrops were excluded. Results: 10.1% of newborns were SGE. Among live births 10% were SGE instead of the 33.5% found in stillbirths (p<0.05). Congenital malformation rate at birth was 12.9% in SGE, 8.5% in AGE and 9.3% in LGE newborns (p<0.05). The global congenital malformation prevalence rate at birth was 9.5%; 9.4% in live newborns and 33% in stillbirth. Conclusión: The FGR increase the risk of late fetal mortality and congenital anomalies.

Palabras clave : Fetal growth restriction; late fetal mortality; congenital malformations.
