Insights
Neonatal cerebral infarction is a significant cause of seizures in newborns, often presenting with subtle signs. Early diagnosis via imaging is crucial, as most infants have poor prognoses without timely intervention.
Area of Science:
- Neonatal neurology
- Pediatric neuroimaging
- Cerebrovascular disease
Context:
- Neonatal cerebral infarction is an under-recognized cause of neurological deficits in newborns.
- Convulsions are a common presentation, accounting for 20% of neonatal seizure events.
- Early clinical signs can be subtle, often limited to abnormal muscle tone.
Purpose:
- To analyze the clinical characteristics and prognosis of neonatal cerebral infarction.
- To highlight the importance of early diagnosis and intervention for improving long-term outcomes.
- To raise awareness of this condition among healthcare professionals.
Summary:
- Six cases of neonatal cerebral infarction were identified over one year (0.6% of inpatients).
- Causes included cerebrovascular malformations, intraventricular hemorrhage, and prematurity-related factors.
- Diffusion-weighted MRI (DW-MRI) proved highly valuable for early diagnosis, while cerebral ultrasound showed positive results in most cases.
- Convulsions were the primary presenting symptom in four infants.
- Prognoses were generally poor, with only one infant having a normal outcome at 6-8 months follow-up.
Impact:
- Neonatal cerebral infarction is not rare and should be considered in neonatal convulsions.
- Advanced imaging techniques like DW-MRI are essential for timely diagnosis.
- Delayed diagnosis and widespread lesions are associated with unfavorable long-term prognoses.
- Early detection and intervention are critical for potentially improving outcomes in affected infants.
Objective:
To analyze the relationship between clinical characteristics and prognosis of neonatal cerebral infarction and to draw attention to the disease to improve the long-term outcome through early diagnosis and intervention.
Methods:
The clinical characteristics of 6 confirmed cases were summarized. Perinatal conditions and other factors were analyzed for possible causes of the disease. The survived patients were followed-up for 6-8 months.
Results:
The authors diagnosed 6 cases of neonatal cerebral infarction in one year, which accounted for 0.6% (6/969) of all the in-patients in the same time period. Among them 3 cases were confirmed as cerebrovascular malformations by magnetic resonance angiography (MRA), In 1 case the infarction was due to severe bilateral intraventricular hemorrhage, and in another case the disease was related to comprehensive factors such as prematurity, maternal pregnancy induced hypertension and respiratory failure secondary to bronchopulmonary dysplasia (BPD), and in 1 case the cause was undetermined. Four out of the 6 patients presented with varied forms of convulsions, which became the second leading cause for all the neonatal convulsive events (20%). None of the patients had localized neurological signs in the early course except for abnormal muscular tone of some extent. Cerebral ultrasound scanning in 5 out of 6 cases showed positive results. The diffusion-weighted magnetic resonance imaging (DW-MRI) was highly valuable for early confirmative diagnosis. Only one case was found normal within one year of follow-up and all the other 5 cases had unfavorable prognoses of varied severity.
Conclusion:
Neonatal cerebral infarction is not a rare condition and should be considered as one of the important causes for neonatal convulsion. Imaging study is the main technique for diagnosis. The prognoses were poor for those cases for whom early diagnosis and treatment can not be made or those with widespread cerebral lesions.
