Abstract Background Transcranial Doppler (TCD) pulsatility index (PI) has traditionally been
interpreted as a descriptor of distal cerebrovascular resistance (CVR). We sought to …

Continuous monitoring of mean intracranial pressure (ICP) has been 17 an essential part of
neurocritical care for more than half a century. Cerebrospinal 18 pressure–volume …

Understanding the dynamic relationship between cerebral blood flow (CBF) and the
circulation of cerebrospinal fluid (CSF) can facilitate management of cerebral pathologies …

Background Cerebrospinal compliance describes the ability of the cerebrospinal space to
buffer changes in volume. Diminished compliance is associated with increased risk of …

Introduction The purpose of this study was to investigate the relationship between pulsatility
index (PI) or optic nerve sheath diameter (ONSD) and intracranial pressure (ICP) in patients …

The critical closing pressure (CrCP) of the cerebral circulation depends on both tissue
intracranial pressure and vasomotor tone. CrCP defines the arterial blood pressure (ABP) at …

Abstract The Monro-Kellie doctrine describes the principle of homeostatic intracerebral
volume regulation, which stipulates that the total volume of the parenchyma, cerebrospinal …

Coupling of the cardiovascular and cerebrospinal fluid (CSF) system is considered to be
important to understand the pathophysiology of cerebrovascular and craniospinal disease …

BACKGROUND: Endoscopic third ventriculostomy (ETV) has been used predominantly in
the pediatric population in the past. Application in the adult population has been less …

Abstract Background Transcranial Doppler (TCD) has been used to estimate ICP
noninvasively (nICP); however, its accuracy varies depending on different types of …
