Bilateral opacification occurred in 12 subjects, eight of whom had pituitary tumors. Unilateral partial obliteration was encountered in...

متن کاملImpedance Phlebography
Impedance phlebography, a noninvasive approach to the diagnosis of venous thrombosis, depends on decreasing calf electrical impedance in normal subjects during inspiration. In order to assess the relationship between impedance changes and inspiratory volume, normal subjects were studied at various depths of inspiration. The mean inspiration volume required for a result indicating no evidence of...
متن کاملOrbital varix diagnosed by color Doppler flow imaging--case report.
A 66-year-old male presented with an angiographically occult orbital varix. Angiography and phlebography failed to demonstrate the lesion. Computed tomography angiography showed the varix, but not the vascular flow. Color Doppler flow imaging clearly demonstrated the well-defined varix with slow flow velocity, as well as the precise anatomical location. We recommend color Doppler flow imaging a...
متن کاملOrbital phlebography in idiopathic intracranial hypertension and chronic tension-type headache
BACKGROUND Pathologic signs in orbital phlebographies have been reported in various neurological diseases. PURPOSE To study if pathologic signs in orbital phlebography may be markers of inflammation primarily affecting intracranial capillaries, which would cause intracranial hypertension. MATERIAL AND METHODS Two groups with different intracranial cerebrospinal fluid pressures (Pcsf) were c...
