Effect of temporary subdural-peritoneal shunt on subdural effusion with subarachnoid effusion
Insights
Subdural effusions with ruptured subarachnoid effusion in infants were diagnosed using CT and other imaging. Treatment via subdural-peritoneal shunt or conservative management showed good outcomes in most cases.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Diagnostic Imaging
Background:
- Subdural effusions, particularly with ruptured subarachnoid effusion, present a diagnostic challenge in infants.
- Understanding the dynamics of cerebrospinal fluid (CSF) is crucial in pediatric neurological conditions.
Purpose of the Study:
- To describe a series of pediatric cases with subdural effusion and ruptured subarachnoid effusion.
- To evaluate the efficacy of different treatment modalities for this condition in infants.
Main Methods:
- Diagnosis was established using computed tomography (CT), air study, and radioisotope (RI) cisternography.
- Treatment involved either temporary subdural-peritoneal (S-P) shunting for symptomatic cases or conservative management for asymptomatic cases.
- A cohort of 14 children up to 10 months of age was studied.
Main Results:
- Ten infants presented with symptoms of increased intracranial pressure (ICP) and underwent S-P shunt placement.
- Four infants were asymptomatic and managed conservatively.
- Successful outcomes were observed in 9 out of 10 shunted cases and 2 out of 4 conservatively treated cases.
Conclusions:
- Subdural effusion with ruptured subarachnoid effusion is a distinct entity observable in young children.
- Cerebrospinal fluid (CSF) absorption imbalance during transitional CSF dynamics may be a key pathogenetic factor.
- Both surgical (S-P shunt) and conservative treatments can yield favorable results depending on clinical presentation.
Abstract:
A special entity called subdural effusion with ruptured subarachnoid effusion, which was diagnosed by CT, air study, and RI cisternography, was observed in 14 children of up to 10 months of age. 10 cases that showed symptoms of increased intracranial pressure (ICP) were treated by temporary subdural-peritoneal (S-P) shunt, and the remaining 4 cases that showed no symptoms of increased ICP were treated conservatively. 9 of the 10 cases treated by S-P shunt and 2 of the 4 cases treated conservatively showed good results. Poorly balanced absorption of cerebrospinal fluid (CSF) during the special transitional period of the CSF dynamics may be thought to be a pathogenetic factor.
