Occlusion of the pig superior sagittal sinus, bridging and cortical veins: multistep evolution of sinus-vein thrombosis
1992
✓ Cerebral sinus-vein thrombosis may lead to severe hemodynamic changes, elevated intracranial pressure (ICP), and brain edema. It is supposed that progression of the thrombus from the sinus into bridging and cortical veins plays a key role in the development of these pathophysiological changes, but this hypothesis lacks experimental proof. The aim of this study, using a novel animal model of sinus-vein thrombosis, was to evaluate the effects of a standardized occlusion of the superior sagittal sinus and its bridging and cortical veins on hemodynamic alterations, on brain water content, and on ICP in domestic pigs. In 10 animals, the middle third of the superior sagittal sinus was occluded …
Myxoma of the orbit: a clinicopathologic report.
1990
A 27-year-old white man developed proptosis of his left eye over a period of 2 years. It was associated with vertical diplopia and displacement of the left globe down and laterally. Ultrasonography showed a cystic mass in the superior orbital region. Computed tomography (CT) demonstrated a solid, well-defined lesion behind the globe displacing the optic nerve medially. A transfrontal craniotomy revealed a nodular mass in the posterior and superior orbit, which extended anteriorly up to the globe. Histopathology, immunohistochemistry, and transmission electron microscopy proved the tumor to be a myxoma.
