ABSTRACT

SUMMARY:

To establish an unprovable diagnostic indicative index reference for ultrasound examination of the fetal cerebral ventricles, based on the morphological characteristics throughout fetal nervous system development. Key ultrasonic morphological indicators of fetal ventricular development, which includes frontal horn width (FHW), occipital horn width (OHW), width of 3rd ventricle, cavity of septum pellucidum (CSP), width and length of 4th ventricle and thalamo-occipital distance (TOD) had been measured and analyzed collectively. All data of the indicators was collected on singleton pregnant woman between 16-39 weeks of gestational age (GA), between November 2017 and June 2021 at the Second Hospital of Dalian Medical University. A total of 235 pregnant women were enrolled in the cross section study; another 36 pregnant women voluntarily joined a timeline-tracking follow-up study (cohort study) under the same examining criteria. A decrease of FHW and OHW of the lateral ventricles was observed as GA increased; while dimensional values of TOD, 3rd ventricle, CSP, as well as 4th ventricle increased with GA. Most of these indicators showed an enhanced variation tendency within a certain period of GA. Moreover, values of FHW and TOD showed asymmetry of the two hemispheres within the whole GA. Our findings revealed the morphological regularity of fetal ventricular development, which would instructively enhance the relative clinical ultrasound diagnosis; moreover, TOD also showed regularly changes as GA increased, suggesting that TOD should be considered as an additional routine ultrasonic indicator for fetal ventricular development.
RESUMEN
RESUMEN El objetivo del estudio fue establecer un índice de referencia indicativo diagnóstico no demostrable para el examen ecográfico de los ventrículos cerebrales fetales, basado en las características morfológicas a lo largo del desarrollo del sistema nervioso fetal. Indicadores morfológicos ultrasónicos clave del desarrollo ventricular fetal, que incluyen el ancho del cuerno frontal (FHW), el ancho del cuerno occipital (OHW), el ancho del tercer ventrículo, la cavidad del septo pelúcido (CSP), el ancho y el largo del cuarto ventrículo y la distancia tálamo-occipital (TOD) fueron medidos y analizados conjuntamente. Todos los datos de los indicadores se recopilaron en mujeres embarazadas de un solo feto entre 16 y 39 semanas de edad gestacional (EG), entre noviembre de 2017 y junio de 2021 en el Segundo Hospital de la Universidad Médica de Dalian. Un total de 235 mujeres embarazadas se inscribieron en el estudio transversal; otras 36 mujeres embarazadas se unieron voluntariamente a un estudio de seguimiento de línea de tiempo (estudio de cohorte) bajo los mismos criterios de examen. Se observó una disminución de FHW y OHW de los ventrículos laterales a medida que aumentaba la GA; mientras que los valores dimensionales de TOD, tercer ventrículo, CSP y cuarto ventrículo aumentaron con GA. La mayoría de estos indicadores mostraron una tendencia de variación mejorada dentro de un cierto período de GA. Además, los valores de FHW y TOD mostraron asimetría de los dos hemisferios dentro de toda la AG. Nuestros hallazgos revelaron la regularidad morfológica del desarrollo ventricular fetal, lo que mejoraría de manera instructiva el diagnóstico clínico de ultrasonido relativo; además, TOD también mostró cambios regulares a medida que aumentaba la GA, lo que sugiere que TOD debe considerarse como un indicador ultrasónico de rutina adicional para el desarrollo ventricular fetal.
