Summary
Craniosynostosis, premature skull fusion, can reduce cerebral blood flow. Surgical correction normalizes blood flow, suggesting it
Area of Science:
- Pediatric Neurosurgery
- Radiology
- Developmental Biology
Background:
- Craniosynostosis involves premature fusion of cranial sutures.
- Isolated cases were previously considered cosmetic.
- Potential for neurological impact was unclear.
Observation:
- This study assessed cerebral perfusion using SPECT scans before and after surgery.
- Seven infants (3-28 months) with craniosynostosis were included.
- Preoperative scans showed perfusion asymmetry in compressed areas.
Findings:
- Five of seven patients exhibited normalized cerebral blood flow post-surgery.
- Preoperative perfusion asymmetry ranged from 0-30% (mean 13%).
- No new perfusion defects were observed after reconstruction.
Implications:
- Craniosynostosis may cause decreased cerebral blood flow due to brain compression.
- Cranial reconstruction corrects perfusion asymmetry, indicating functional benefits beyond aesthetics.
- Early surgical intervention is supported to prevent potential CNS compromise.
