[The use of magnetic resonance venography in diagnosis of cerebral venous blood flow disorders].
The paper presents an examination of 85 patients aged 16-72 years with cerebral venous dyscirculation resulted from the obstruction of cerebral venous sinuses, major veins of the neck and upper regions of the mediastenum. 70 healthy volunteers were also observed. Magnetic-resonance venography of brachyocephal veins and venous sinuses and ultrasound duplex scanning of internal jugular veins together with colored mapping of the blood flow were performed. Both the causes and the magnetic-resonance semiotics of the obstructive damages of brachyocephal veins and of the cerebral venous sinuses were described. The criteria for hemodynamic significance of the obstruction of brachyocephal veins were defined in case of extravasal compression of brachyocephal veins.
