Highlights
Many investigators have shown marked abnormalities of CSF and parenchymal pulse pressure in hydrocephalus, and Greitz, Bateman, and Egnor have proposed that abnormalities of pulsatility are at the root of the pathophysiology of hydrocephalus
We have studied the phase relations between the carotid arterial pressure pulse and the intracranial pressure (ICP) pulse in dogs as a function of mean intracranial pressure
With lowering of ICP, there was an increase in the lead of the ICP pulse with respect to the carotid pulse to about 100 degrees
Summary
Pressure phase relationships between carotid arterial pressure and intracranial pressure: the 'violin' analogy of intracranial pulsations.
