Insights
The grading of periventricular echodensities (PVE) in preterm infants correlates with the risk and timing of white matter cystic lesions. Higher PVE grades indicate increased morbidity and earlier lesion development.
Area of Science:
- Neonatal neurology
- Pediatric imaging
- Neurodevelopmental disorders
Background:
- Periventricular echodensities (PVE) are common in preterm infants.
- Understanding PVE grading's impact on white matter injury is crucial for prognostication.
Purpose of the Study:
- To investigate the association between PVE grading and the morbidity and timing of periventricular white matter cystic lesions.
- To determine if PVE severity predicts adverse outcomes in preterm neonates.
Main Methods:
- Retrospective cohort study of 120 preterm infants diagnosed with PVE via ultrasonography.
- Analysis of PVE grading (I, II, III) in relation to gestational age, birth weight, and cystic lesion development.
Main Results:
- PVE grading correlated with birth weight but not gestational age.
- Overall morbidity of cystic lesions was 24%.
- PVE III showed significantly higher morbidity (65%) and earlier onset of cystic lesions compared to PVE II (21%).
Conclusions:
- PVE grading is a significant predictor of periventricular white matter cystic lesion morbidity.
- The severity of PVE influences the timing of cystic lesion occurrence in preterm infants.
Objective:
To understand the relationship of the grading of periventricular echodensities (PVE) with the morbidity and the occurrence time of periventricular white matter cystic lesions in preterm infants.
Methods:
A retrospective, single-centre cohort study of 120 preterm infants with PVE diagnosed by ultrasonography between February 2005 and May 2008 was performed. The infants had a median gestational age of 32 weeks and a median birth weight of 2 230 g.
Results:
Fifty-two infants (43%) were diagnosed as having PVE I, 42 infants (35%) having PVE II, and 26 infants (22%) having PVE III. The grading of PVE was closely related to birth weight, but not with gestational age. The total morbidity of periventricular white matter cystic lesions was 24% (29/120). The morbidity of the cystic lesions in PVE III patients (65%) was significantly higher than that in PVE II patients (21%) (<0.01). The PVE III patients developed the cystic lesions earlier than the PVE II patients.
Conclusions:
The grading of PVE is closely related to the morbidity and the occurrence time of periventricular white matter cystic lesions in preterm infants.
