In this article, by using the term "perivenous space" we refer to the parenchymal areas surrounding the hepatic veins.
The mechanism for potential vaccine damage could be the final common pathway for damage from other insults, which lead to similar pathology: edema, infiltration of the walls of veins, a perivenous inflammatory reaction, and perivenous hemorrhages.
In the meantime, hypertension could increase the collagen biosynthesis and deposition in perivascular spaces [55], which could have similar effect to the perivenous cuffs in MS patients [56].
However, collagen external scaffolds (CES), as a perivenous support for vein grafts, have not been reported to our knowledge.
When the hepatic tissues of the rats which were given paracetamol were examined, a moderate increase in the connective tissue, granular degeneration, necrotic cells, necrosis in the lobular center, early fibrosis in the perivenous region and portal vein congestion with periportal area infiltration characterized with increased inflammatory cells at moderate and severe levels were observed (Figure 2).
Ophthalmoscopic examination revealed vitritis (+1), widespread perivenous sheathing in the peripheral retina, and exudation in both eyes, but more pronounced in the right eye (Figure 1).
The liver indeed normally exhibits metabolic zonation, that is, heterogenous distribution of metabolic functions across the lobule; in particular, oxygen-dependent functions like gluconeogenesis, ureagenesis, and oxidative phosphorylation predominate in the periportal region, whereas glycolysis, lipogenesis, and xenobiotic metabolism take place predominantly in the pericentral (perivenous) region [22,23].
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 streak artifacts.
