متن کاملRecanalization of the falcine sinus after venous sinus thrombosis.
Thrombosis of the straight and transverse sinuses associated with a large hemorrhagic venous infarct developed in an infant with large chronic subdural fluid collections after drainage of the subdurals. CT and MR studies obtained before and after the onset of venous sinus thrombosis showed interval widening of a segment of the posterior falx between the vein of Galen and the superior sagittal s...
متن کاملVenography and venous pressure monitoring in dural sinus meningiomas.
This study was undertaken to determine the impact of dural sinus venography and pressure measurements in the evaluation of patients with meningiomas involving the dural sinuses. Of three patients who had MR imaging, arteriography, and dural sinus venography, the latter method better delineated the site and extent of tumor invasion in all three patients. Pressure measurement in one patient refle...
