Hypothesis
Can the cavernous sinus veins play a role in cerebrospinal fluid absorption?
Conclusion
The study suggests that cerebrospinal fluid may be absorbed through unconventional pathways involving the cavernous sinus veins.
Supporting Evidence
- Microfil was observed in the cavernous sinus and surrounding tissues.
- CSF may be absorbed into veins and lymphatics outside the skull.
- Unconventional pathways for CSF absorption were identified.
Takeaway
The study found that fluid can move from the brain to the veins in the head, which might help explain how the body gets rid of brain fluid.
Methodology
Microfil was infused into the subarachnoid space of sheep, and tissues were examined for fluid distribution.
Limitations
The study was conducted post mortem, which may limit the physiological relevance of the findings.
Participant Demographics
Randomly bred sheep, including newborns and adults.
