[Comparative echoventriculographic studies in premature, low weight and mature infants]
Insights
Preterm infants show smaller cerebral matter and wider lateral ventricles compared to healthy newborns. This may indicate delayed brain maturation, which can improve over time.
Area of Science:
- Neuroscience
- Pediatrics
- Medical Imaging
Context:
- Evaluating brain development in preterm and low-weight infants is crucial for early intervention.
- Cranial ultrasound (echoencephalography) is a non-invasive tool for assessing brain structures in neonates.
Purpose:
- To compare the dimensions of lateral and third ventricles and parietal cerebral matter in preterm infants versus healthy controls.
- To investigate potential causes for observed differences, including atrophic changes and delayed brain maturation.
Summary:
- Measurements of lateral and third ventricles and parietal cerebral matter were taken using one-dimensional echoencephalography in 135 preterm and 17 low-weight infants up to 30 months.
- Preterm infants exhibited significantly smaller parietal cerebral matter diameter and body region index, with wider lateral ventricles compared to healthy controls.
- Findings suggest that reduced cerebral matter and enlarged ventricles in preterm infants may stem from delayed brain maturation rather than solely atrophic changes, with potential for developmental compensation.
Impact:
- Provides insights into the neurodevelopmental trajectory of preterm infants.
- Highlights the importance of considering delayed maturation as a factor in brain structure variations.
- Informs clinical assessment and potential therapeutic strategies for optimizing neurodevelopmental outcomes in high-risk infants.
Abstract:
In 135 preterm and low-weight prematures and in 17 low-weight infants with normal time of gestation the diameter of the body region (= Cella media region) of the lateral ventricles and the width of the third ventricle were measured by means of one-dimensional echoencephalography. The observations were made during the period of the first 30 months. The diameter of the parietal cerebral matter was defined as difference of the biparietal skull diameter minus width of the body region of both lateral ventricles. By comparing healthy, maturely born children with preterm children the fetal age was taken as a basis. Statistics were taken from the age of one month onward. The preterm children showed significant lower values for the diameter of the cerebral matter and the index of the body region. Accordingly the values for the width of the body region were higher. The results are explaned not only with atrophic changes. According to our investigations they also can be caused by a retarded maturation of brain, which can be compensated partly or completely in the course of the child's development.
