Venous malformations (VMs) are the most common vascular developmental anomalies
(birth defects). These defects are caused by developmental arrest of the venous system …

Assessment of cerebral venous return is growing interest for potential application in clinical
practice. Doppler ultrasound (DUS) was used as a screening tool. However, three meta …

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 …

Under the auspices of the International Society for Neurovascular Disease (ISNVD), four
expert panel committees were created from the ISNVD membership between 2011 and …

BACKGROUND AND PURPOSE: The hypothesis that MS could be provoked by a
derangement of the blood outflow from the brain has been largely discredited. In part, it was …

Background The quantification of the flow returning from the head through the cervical veins
and the collaterals of the internal jugular vein (IJV), is becoming of prominent interest in …

To analyze the presence of chronic cerebrospinal venous insufficiency parameter and
vascular abnormalities, in the internal jugular veins (IJVs) and/or vertebral veins in sitting …

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 …

BACKGROUND: Magnetic resonance imaging and echo color Doppler (ECD) scan
techniques do not accurately assess the cerebral venous return. This generated …

Purpose To evaluate relationship between Meniere disease (MD) and chronic cerebrospinal
venous insufficiency (CCSVI) using ultrasound, magnetic resonance (MR) imaging, and …
