Transcranial Ultrasound in Evaluation of Brain Insults in High-Risk Neonates
Abstract: Background: Brain injury in high-risk neonates is a major cause of neonatal morbidity and mortality. Early detection of intracranial abnormalities is essential for timely intervention. Transcranial ultrasound (TCUS) is a bedside, non-invasive, radiation-free imaging modality widely used for neonatal neuroimaging. Objectives: To evaluate the role of transcranial ultrasound in the detection and characterization of brain insults in high-risk neonates and to identify clinical and perinatal predictors of abnormal neurosonographic findings. Methods: This prospective observational study was conducted at a tertiary care teaching hospital that included 100 high-risk neonates admitted to the NICU. All infants underwent transcranial ultrasound through the anterior fontanelle using a standardized imaging protocol. Clinical, demographic, and neurosonographic data were analyzed. Associations between ultrasound findings, gestational age, birth weight, clinical manifestations, and final diagnoses were assessed using chi-square tests, Cramer's V, and multivariable logistic regression. Results: The mean gestational age was 34.81 ± 4.40 weeks and mean birth weight was 2.26 ± 0.70 kg. Abnormal ultrasound findings were detected in 32% of neonates. Ventriculomegaly was present in 12%, periventricular echogenicity in 14%, ventriculitis in 7%, and germinal matrix hemorrhage in 3%. The most common diagnoses were periventricular leukomalacia (8%), hydrocephalus (7%), meningitis (6%), hypoxic ischemic encephalopathy (5%), and germinal matrix hemorrhage (3%). Significant associations were observed between gestational age and ventriculomegaly (p=0.014), gestational age and periventricular echogenicity (p<0.001), ventriculomegaly and hydrocephalus (p<0.001), ventriculitis and meningitis (p<0.001), and caudothalamic echogenicity and germinal matrix hemorrhage (p<0.001). Independent predictors of abnormal ultrasound findings included very preterm birth (AOR 5.8), seizures (AOR 4.6), low birth weight (AOR 2.9), and apnea (AOR 2.4). Conclusion: Transcranial ultrasound is an effective first-line neuroimaging tool for early detection of brain insults in high-risk neonates. Prematurity, low birth weight, seizures, and apnea significantly increase the likelihood of abnormal neurosonographic findings, supporting routine screening in these vulnerable groups.
