Infusion of saline (in the second lumen) following the contrast injection assists in the low dose CCTA initiative by improving contrast volume utilization, prolonging the peak of injection, and reducing perivenous
Chronic alcoholism is linked with hypoxia in hepatocytes, particularly the perivenous
Local intolerance reactions, including moderate irritation associated with infiltration of inflammatory cells were observed after perivenous
injection in rabbits suggesting the possibility of local irritation if the contrast medium leaks around the veins in a clinical setting [see Warnings and Precautions (5.
Functional heterogeneity of periportal and perivenous
Glutathione replenishment capacity is lower in isolated perivenous
than in periportal hepatocytes.
PML can be differentiated from many other demyelinating diseases by the absence of perivenous
inflammation and therefore a lack of enhancement on imaging.
14,21) In the majority of these (Pattern 2) cases, active lesions were typically perivenous
in location, characterized by the precipitation of activated complement and IgG on degenerating myelin sheaths and associated with the presence of remyelinating shadow plaques elsewhere in the CNS.
A high-sucrose diet increases gluconeogenic capacity in isolated periportal and perivenous
Features graded in fields 2-8 include haemorrhages and/or microaneurysms, hard exudates, cotton wool spots, venous calibre abnormalities, venous sheathing, perivenous
exudates, arteriolar abnormalities, IRMAs, arteriovenous nicking, neovasularisation elsewhere (NVE), fibrous proliferation, retinal elevation, preretinal haemorrhages, and vitreous haemorrhage.
Congestion and edema of the brain, widespread perivenous
demyelination mainly in the cerebral and cerebellar white matter, basal ganglia, brainstem, and spinal cord, and in severe cases, necrosis of vessels and perivascular tissue are the histologic characteristics.
Effect of chronic ethanol feeding on glutathione and functional integrity of mitochondria in periportal and perivenous
Distribution of hepatic glutaminase activity and mRNA in perivenous
and periportal hepatocytes.
