Central thalamic areas drain via a series of small veins into the internal cerebral veins superiorly and the basal veins of Rosenthal inferiorly.
Abdominal causes Relieve causes of intra-abdominal hypertension. Failure of venous efferent flow to precisely match arterial afferent flow will yield immediate and dramatic changes in intracranial blood volume and pressure. Concepts of cerebral perfusion pressure and vascular compression during intracranial hypertension. Diffuse compression of the venous system Diffuse brain swelling can also cause generalised venous compression creating an internal starling type resistor.

While the traditional Kellje doctrine holds, imbalances in arterial inflow and venous outflow also affect ICP. The full legend is within the figure.
The Monro-Kellie hypothesis: applications in CSF volume depletion.
It is our experience that occipital skull fractures over the right transverse sinus are more significant since this is the dominant sinus in most people. Ulus Travma Acil Cerrahi Derg ; Archived from the original on April.

Depressed skull fracture overlying the superior sagittal sinus as a cause of benign intracranial hypertension. As you assess his pupils what reaction would confirm your suspicion of increasing intracranial generalized seizure client which nursing assessment priority for detailing the eventSeizure was minute duration including tonicclonic activity [ View of a coronal section through the head, showing the falx cerebri, the tentorium cerebelli, and the associated venous sinuses.
It is important to note that most of monri blood in the cranial cavity is contained in the low-pressure venous systemso venous compression serves as a means of displacing blood volume 2. Post-traumatic superior sagittal sinus thrombosis.

This description fails to explain the importance of volume flow. Multiple clinical conditions and the cerebral effects of altitude and microgravity relate to imbalances in this dynamic rather than ICP per se.
