PURPOSE To determine the ability of transtemporal power- and frequency-based transcranial color-coded duplex sonography to aid in the assessment of cerebral veins and sinuses, as well as to provide reference data for flow direction and velocity. METHODS Using a color duplex device equipped with a 2.0/2.5-MHz sector scan, we insonated 120 healthy volunteers and three patients with cerebral ven...

thromboembolic phenomena are the serious consequences of assisted reproductive technology. we present a case of cerebral sinus vein thrombosis (cvst) following ovarian hyper stimulation syndrome (ohss). ten days after recovering from ohss, the patient presented in the emergency department with thunderclap headache. her magnetic resonance venography (mrv) showed occluded left transverse sinus an...

A case of multiple cerebral varices located in the superficial cerebral veins and ipsilateral internal jugular vein is reported.

The great cerebral vein of Galen extends from the junction of the two internal cerebral veins under the splenium of the corpus callosum to the commencement of the straight sinus. Arteriovenous aneurysms of this vein are rare congenital anomalies and only 22 cases have been found in a review of the literature. Other types of cerebral arteriovenous aneurysms are not so unusual. Their true inciden...

A technique for continuous measurement of cerebral venous outflow in the rat is described. The method involves cannulation of one retroglenoid vein close to its exit from the skull, and diversion of cerebral venous blood through a closed extracorporal circuit with a drop recording device, the blood being returned to the central venous circulation via a catheter in the external jugular vein. Occ...

The vein of Galen is the largest of the deep cerebral veins formed posterior to the pineal body by confluence of the two internal cerebral veins. It curves sharply upward around the splenium of the corpus collosum and drains the deep medially located veins of the diencephalon, basal ganglia, and mid brain. Dilatation of the vein of Galen results from the force of arterial blood either directly ...
