ABSTRACT
INTRODUCTION:
Transfontanellar brain ultrasound is an essential tool for monitoring the size of the ventricles in preterm neonates and has many advantages over other alternative diagnostic techniques, including its accessibility and non-use of ionizing radiation. When considering the normal ventricular size, it is essential to have reference measurements based on age-matched populations. The objective of this article is to present our reference measures, based on a sample of preterm infants that we have studied.METHODS:
A retrospective observational study was conducted. Measurements of the Levene index, frontal horn thickness, and Evans index were obtained in preterm neonates from 25 to 45 weeks, over a period of 5 years, between January 2016 and December 2020. After applying the exclusion criteria, a sample of 199 patients and 350 ultrasound scans were obtained. The independent samples t-test and the Mann-Whitney test were used for the comparison of samples.RESULTS:
The distribution of the right and left Levene indices was normal (Shapiro-Wilk test with pâ¯=â¯0.16 and 0.05, respectively), unlike the thickness distribution of the frontal horns (pâ¯<â¯0.05 on both sides). No significant differences were detected between the sexes (pâ¯=â¯0.08). A linear correlation was found between the biparietal diameter and the Levene index.CONCLUSION:
From the results obtained in our study, we present reference tables for ventricular size, with the 3rd, 25th, 50th, 75th, and 97th, being the first ones made in our country.Palabras clave
