PORTAL VENOGRAPHY BY SELECTIVE ARTERIAL CATHETERIZATION

Percutaneous 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...

Tissue Selective Magnetic Resonance Subtraction Venography

We have developed a procedure to image the major veins of the brain using three dimensional magnetic resonance imaging sequences. This procedure is based on the selective enhancement of blood vessels following intravenous administration of contrast media such as gadolinium. A simple subtraction is performed between the post-contrast and pre-contrast MR images after correcting for overall intens...

New technique for portal catheterization in dogs.

Portal vein catheterization and selective angiography in diagnosis of total anomalous pulmonary venous connexion.

common pulmonary vein can beperformed using a small dose ofcontrast medium. This delineates the anatomical distribution of the pulmonary veins and site or sites of pulmonary venous obstruction more accurately than recirculation angiography. Direct pulmonary venous angiography eliminates the needfor the injection of contrast medium into the arterial phase of the pulmonary circulation. This, toge...

Vascular injury after arterial catheterization.

Twenty-three cases of arterial injury after 8,208 arterial catheterizations for diagnostic or therapeutic indications at Glasgow Royal Infirmary are reviewed. Clinical presentation included haematoma formation, development of an acutely ischaemic limb or a false aneurysm. Patients with valvular heart disease are identified as a high risk group. Nine cases were managed by simple suture of the pu...
