We describe the neuroradiologic findings in a 7-year-old boy with anomalous intracranial venous drainage and cerebral calcification. CT scans demonstrated that his scalp mass was a plexus of scalp veins filled through the emissary foramen, and there were cerebral calcifications. Angiography revealed bilateral sigmoid sinus atresia with most of the intracranial venous drainage via the prominent ...

The venous efflux from cerebral dural venous sinus into the extracranial venous drainage is predominantly based on sigmoid venous sinus draining into the internal jugular vein. In the fetal stage, the rapid growth of cerebral hemispheres leads to an enlargement of transverse venous sinuses in somewhat disproportionate manner to growth of sigmoid venous sinus and internal jugular vein. Therefore...

Many cases of patients who have died from air embolism during surgical operations have been reported, and in some of these the mode of death has suggested a cerebral lesion, but in very few have the brains been carefully examined at necropsy. As a result there is at present a state of uncertainty as regards the nature and pathology of cerebral air embolism. Bohorfoush (1943) described finding "...

Cerebral blood volume and intracranial pressure may be modified by influences on cerebral veins. The known adrenergic innervation of cerebral veins and their sensitivity to norepinephrine raised the question, whether pial veins can be selectively influenced through adrenoceptors in vivo. Therefore, alpha] and alpha2 adrenoceptor agonists and antagonists were locally injected into the perivascul...

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

Cerebral blood volume and intracranial pressure may be modified by influences on cerebral veins. The known adrenergic innervation of cerebral veins and their sensitivity to norepinephrine raised the question, whether pial veins can be selectively influenced through adrenoceptors in vivo. Therefore, alpha 1 and alpha 2 adrenoceptor agonists and antagonists were locally injected into the perivasc...

Venous system can be classified as pulmonary veins, systemic veins and venous sinuses that are present only within the skull. Cerebral venous system is divided into two main parts, the superficial and the deep system. The main assignment of veins is to carry away deoxygenated blood and other maleficient materials from the tissues towards the heart. Veins have thinner walls and larger lumina tha...

Cerebral venous thrombosis, including thrombosis of cerebral veins and major dural sinuses, is an uncommon disorder in the general population. However, it has a higher frequency among patients younger than 40 years of age, patients with thrombophilia, pregnant patients or those receiving hormonal contraceptive therapy or has foreign body such as catheter in their veins or arterial system. In th...
