Atrophy and maldevelopment of the ipsilateral cerebral hemisphere after acute subdural hematoma in infants
Insights
Acute subdural hematoma in infants can lead to prolonged hemispheric swelling and increased intracranial pressure. Survivors often develop cerebral hemisphere atrophy, impacting long-term neurological outcomes.
Area of Science:
- Pediatric Neurosurgery
- Neurology
- Medical Imaging
Background:
- Acute subdural hematoma (ASH) in infants is a rare but serious condition.
- Understanding the long-term sequelae of ASH in this age group is crucial for effective management.
Observation:
- A study reviewed nine infants under 4 years with ASH between 1980 and 1991.
- Five infants required surgical hematoma evacuation.
- Eight infants survived beyond one month post-admission.
Findings:
- Infants requiring evacuation and surviving longer than one month experienced prolonged ipsilateral hemispheric swelling for two weeks.
- Elevated intracranial pressure (>25 mm Hg) was noted during this swelling period.
- Four surviving infants developed ipsilateral cerebral hemisphere atrophy post-hematoma evacuation.
Implications:
- Prolonged hemispheric swelling and elevated intracranial pressure are significant postoperative complications in infants with ASH.
- Cerebral atrophy following ASH may represent a long-term consequence impacting neurological development.
- Further research into the pathophysiology of ASH-related cerebral atrophy is warranted.
Abstract:
Among nine infants aged less than 4 years with acute subdural hematoma admitted between 1980 and 1991, five required evacuation of a hematoma. Eight of them survived longer than 1 month and the remaining patient who had a hematoma removal died 3 days postoperatively. The four infants who required evacuation of a hematoma and survived longer than 1 month had prolonged hemispheric swelling ipsilateral to the hematoma lasting for 2 weeks postoperatively. Intracranial pressure was higher than 25 mm Hg during this period. Diffuse high density was observed in the affected hemisphere in one patient 12 days after injury, which was assumed to be hemorrhagic infarction. Subsequently, these four infants developed atrophy of the cerebral hemisphere ipsilateral to the hematoma. The pathophysiology of the atrophy of the cerebral hemisphere ipsilateral to the acute subdural hematoma is discussed.
