We assessed the hemodynamic effects induced by the thoracic pump in the intra-and
extracranial veins of the cerebral venous system on healthy volunteers. Activation of the …

Internal jugular veins are the major cerebral venous outflow pathway in supine humans. In
upright humans the positioning of these veins above heart level causes them to collapse. An …

In supine humans the main drainage from the brain is through the internal jugular vein (IJV),
but the vertebral veins (VV) become important during orthostatic stress because the IJV is …

This article discusses the biophysical aspects of venous outflow from the brain in healthy
individuals and in patients with chronic cerebrospinal venous insufficiency. Blood flows out …

We developed a mathematical model of the cerebral venous outflow for the simulation of the
average blood flows and pressures in the main drainage vessels of the brain. The main …

Objective: The gravitational gradient is the major component to face when considering the
physiology of venous return, and there is a growing interest in understanding the …

Mechanical ventilation with positive end-expiratory pressure (PEEP) may prevent venous air
embolism in the sitting position because cerebral venous pressure (Pcev) could be …

ABSTRACT BACKGROUND Although there exists a large body of knowledge on the
regulation of arterial cerebral hemodynamics, little is known about the cerebral venous …

The aim of this study was to analyse the cerebral venous outflow in relation to the arterial
inflow during a Valsalva manoeuvre (VM). In 19 healthy volunteers (mean age 24.1±2.6 …
