[Pathogenesis of persistent subdural effusions in infants (author's transl)]

|January 1, 1978
Summary
Persistent subdural effusions in infants may be caused by cerebrospinal fluid (CSF) entering the subdural space. This suggests fluid derivation, not membranectomy, is the preferred treatment.
Area of Science:
- Pediatric Neurosurgery
- Cerebrospinal Fluid Dynamics
- Infant Pathophysiology
Background:
- Current theories on infant persistent subdural effusions lack clinical support.
- Investigating the physiopathology of subdural fluid accumulation in infants is crucial.
Observation:
- Daily electrophoretic analysis of drained subdural fluid revealed the presence of cerebrospinal fluid (CSF).
- Protein concentrations in subdural fluid suggest a direct communication between subarachnoid and subdural spaces.
Findings:
- Persistent subdural effusions are likely supplied or replaced by CSF due to a ruptured communicating hydrocephalus.
- Simple filtration cannot explain the observed protein concentrations in subdural fluid.
Implications:
- Membranectomy may not be the optimal treatment for these effusions.
- Fluid derivation is proposed as the treatment of choice for persistent subdural effusions in infants.
- Understanding CSF dynamics is key to managing infant subdural effusions.
