Jugular venous reflux on magnetic resonance angiography and radionuclide venography
BACKGROUND The relationship between the signal from retrograde venous flow on magnetic resonance angiography (MRA) and retrograde upward flow from the left brachiocephalic vein has not been explored. PURPOSE To reveal the frequency of jugular venous reflux using MRA and nuclear venography in patients being evaluated for cerebral volume and blood flow. MATERIAL AND METHODS A total of 229 pat...
متن کاملVenography at insertion of tunnelled internal jugular vein dialysis catheters reveals significant occult stenosis.
BACKGROUND Tunnelled catheters are widely used to provide vascular access for haemodialysis. Percutaneous insertion of these catheters requires large calibre tissue dilators with the potential to cause trauma to central veins, particularly if anatomical abnormalities are present. METHODS We evaluated the use of venography to identify central vein anatomical abnormalities in 69 consecutive pat...
متن کاملValue of MR venography for detection of internal jugular vein anomalies in multiple sclerosis: a pilot longitudinal study.
BACKGROUND AND PURPOSE CCSVI was recently described in patients with MS. CCSVI is diagnosed noninvasively by Doppler sonography and invasively by catheter venography. We assessed the role of conventional MRV for the detection of IJV anomalies in patients with MS diagnosed with CCSVI and in healthy controls who underwent MRV and Doppler sonography examinations during 6 months. MATERIALS AND ME...
متن کاملPercutaneous portal venography.
Portal venography by percutaneous injection of the spleen was first performed in dogs (Abeatici and Campi, 195I) and the method was later successfully applied in man (Leger, 1951; Boulvin et al., 195I; Campi and Abeatici, I952). In the last few years the method has been routinely used at a number of centres in the British Isles. Atkinson, Barnett, Sherlock and Steiner (I955) have described abou...
