It has been recently proposed that intracranial volume being less than skull volume allows the brain to be to be mobile inside the skull. In the presence of head trauma the brain may move relative to, and collide with, the skull (“rattle”) or be internally deformed by pressure waves (“slosh”), resulting in traumatic brain injury. Both mechanisms can be mitigated, or eliminated by increasing the intra-cranial compartment volume, forcing all parts of the brain and skull to move as a unit. In addition, if the intracranial volume fills the skull, the brain will conduct blast energy waves through with minimal energy absorption by the brain, avoiding tissue displacement and shear. It has been proposed that a way to expand the intracranial volume is to fill it with venous blood. Since the brain blood flow is large, a small degree of resistance to drainage will quickly fill the cerebrovascular compliance. The major route of venous drainage in humans is via the internal jugular veins (IJV). In contrast, most quadrupeds have their head at near heart level and the vertebral venous plexi are the main venous outflow conduits (Lavoie et al., 2008). Therefore, studies of the effects of jugular venous compression on brain blood flow and intracranial blood distribution must be performed in humans.
Aims of the study
Our aim was to study the effects of venous backpressure implemented via jugular vein
Is there a reason they buried it in the article pdf?
