civickiller is right.
Yes, obstructions of the cerebral outflow can be significant. Can cause symptoms of cerebral hypertension.But just to clarify, by the Schelling model, it doesnt cause ccsvi. Schelling suggests that forceful meck movements that activate the neck strap m uscles compress dilated IJV and, in the prsence of J1 obstructions causes forceful reflux above the valve into the deep cerebral veins. If this is true, then obstructions at the skull base protects against that because that forceful reflux cannot get above the obstructions.
All hypothetical thoughts on my part.
Thanks Cece, these are very helpful. You can help me on my papers anytime
