Cerebrospinal fluid pulse pressure and intracranial volume-pressure relationships.
In six anaesthetised and ventilated dogs the CSF pulse pressure was compared with the volume-pressure response (VPR) during continuous inflation of an extradural balloon. Both pulse pressure and VPR increased linearly with the ventricular fluid pressure (VFP) up to a mean VFP of 60 mmHg. At this pressure a breakpoint occurred above which the CSF pulse pressure showed a steeper linear increase, ...
متن کاملEffects of hypercapnia and arterial hypotension and hypertension on cerebrospinal fluid pulse pressure and intracranial volume-pressure relationships.
In twelve anaesthetised, ventilated dogs the effects of hypercapnia and pharmacologically induced arterial hypotension and hypertension on the interrelation between volume-pressure response (VPR) and cerebro-spinal fluid (CSF) pulse pressure were studied during continuous inflation of a supratentorial extradural balloon. Hypercapnia did not significantly affect the intracranial volume-pressure ...
متن کاملIntracranial pressure pulse waveform correlates with aqueductal cerebrospinal fluid stroke volume.
This study identifies a novel relationship between cerebrospinal fluid (CSF) stroke volume through the cerebral aqueduct and the characteristic peaks of the intracranial pulse (ICP) waveform. ICP waveform analysis has become much more advanced in recent years; however, clinical practice remains restricted to mean ICP, mainly due to the lack of physiological understanding of the ICP waveform. Th...
متن کاملIn-vitro Model of Intracranial Pressure and Cerebrospinal Fluid Dynamics
The intracranial cavity experiences complex biological as well as fluid-mechanical interactions. There, brain, blood and cerebrospinal fluid (CSF) cooperate to preserve the homeostasis of the central nervous system (CNS). The brain and spinal cord float within a bath of CSF that is pressurized with respect to the atmosphere. In healthy conditions, circulation of blood and CSF minister the optim...
متن کاملElevated intracranial pressure in patients with spontaneous cerebrospinal fluid otorrhea.
OBJECTIVES/HYPOTHESIS To determine the prevalence of elevated intracranial hypertension in patients with spontaneous cerebrospinal fluid otorrhea (SCSFO). STUDY DESIGN Case series with chart review at a tertiary care academic medical center following institutional review board approval. METHODS A retrospective review was performed of patients undergoing operative repair of SCSFO between Jan...
