ORBITAL VENOGRAPHY

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...

Metrizamide in venography

in psychopathology, which worsened after a three-day washout period and became similar to that seen before metoclopramide treatment. The patient was then treated with the classical neuroleptic haloperidol. At a dose of 45 mg/day the same extrapyramidal syndrome re-emerged and was completely responsive to trihexyphenidyl 2 mg by mouth three times daily. After haloperidol dosage was increased to ...

MR venography of multiple sclerosis.

BACKGROUND AND PURPOSE The distribution of multiple sclerosis (MS) lesions in the brain follows a specific pattern, with most lesions in the periventricular regions and in the deep white matter; histopathologic studies have shown a perivenous distribution. The aim of this study was to illustrate these distribution patterns in vivo using high-resolution MR venography. METHODS Seventeen MS pati...

MSCT venography finds cerebral thromboses

Digital subtraction angiography was traditionally considered the best modality for diagnosing CVT. The procedure's invasive nature, however, coupled with an associated risk of cerebrovascular complications, has led to its increasing replacement by MR imaging, and especially MR venography.2 But MR has a number of its own drawbacks. Several studies have reported limited accuracy of MR venography ...
