RESUMEN
Objetivo:
Determinar los rangos de referencia de la translucencia intracraneal (TIC) en nuestra población. Material ymétodos:
Se ha realizado un estudio de regresión lineal sobre 471 gestaciones únicas sin anomalías asociadas para valorar la relación entre LCC y TIC.Resultados:
Se realizó la medición de TIC en el 98,9%. La TIC presenta una distribución normal con una desviación estándar de 0,4139. La media es 2,0502 mm (0,9-3,6 mm), los percentiles 5 y 95% corresponden con 1,4 y 2,7 mm. La TIC presenta una correlación lineal con la LCC (TIC 0,0125* LCC + 1,2628; R2 0,055 p < 0,0001). Se calcula la TIC estimada para el percentil 5 (0,0125* LCC + 1,2628) − 0,6505. El coeficiente de correlación intraclase es de 0,816 (0,606-0,921; IC 95%).Conclusiones:
La medición del cuarto ventrículo durante la ecografía del primer trimestre es posible y sencilla de realizar. Se recomienda realizar un estudio neurológico ampliado ante mediciones situadas por encima del percentil 95 o inferiores al 5 (AU)ABSTRACT
Objective:
To determine reference ranges for intracranial translucency (ICT) in our population. Material andmethods:
To assess the relationship between crown-rump length (CRL) and ICT, we performed a linear regression analysis of 471 singleton pregnancies without associated anomalies.Results:
ICT was measured in 98.9%. ICT had a normal distribution with a standard deviation of 0.4139. The mean was 2.0502 mm (0,9-3.6 mm), and the 5% and 95% percentiles corresponded to 1.4 mm and 2.7 mm. ICT had a linear correlation with CRL (ICT 0.0125 + 1.2628 * CRL; R20,055 P <0.0001). The estimated ICT was calculated for the 5th percentile (1.2628 + 0.0125 * LCC)- 0.6505. The intraclass correlation coefficient was 0,816 (0606-0921 CI 95%).Conclusions:
Measurement of the fourth ventricle during first trimester ultrasound examination is feasible and is simple to perform. An extended neurological evaluation should be carried out if measurements are above the 95th percentile or below the 9th percentile (AU)
