PURPOSE To assess the effectiveness of self-expanding, cobalt-alloy stents in the treatment of aneurysms in a canine model and to observe the pattern of blood flow and formation of fibrotic scar tissue. METHODS Porous metallic stents were endovascularly placed across the necks of experimentally created side aneurysms in the carotid arteries of three dogs;(More)
PURPOSE To evaluate the biologic response to transjugular intrahepatic portosystemic shunts (TIPS) lined with polycarbonate urethane endografts and the effects of different porosity formulations. MATERIALS AND METHODS Seventeen TIPS were created in non-modified portal hypertensive miniswine with use of porous (n = 6), nonporous (n = 7) polycarbonate(More)
PURPOSE To determine the efficacy of porous metallic stents in the treatment of experimentally created carotid-jugular fistulas. METHODS Carotid-jugular fistulas were constructed surgically in five mongrel dogs. Porous metallic stents were placed endovascularly across the fistula holes within the carotid artery; carotid angiography was performed before,(More)
PURPOSE To determine the efficacy of silicone-covered metallic stents in the treatment of experimentally created carotid-jugular fistulas. METHODS Carotid-jugular fistulas were surgically constructed in six mongrel dogs. Silicone-coated, self-expanding metallic stents were placed across the fistula holes within the carotid artery, and carotid angiography(More)
BACKGROUND AND PURPOSE Carotid fusiform aneurysms are most commonly treated with occlusion of the parent vessel. The purpose of our study was to assess the effectiveness of self-expanding, cobalt-alloy stents in the ablation of experimental fusiform aneurysms with preservation of the parent vessel in a carotid artery model. METHODS Porous metallic stents(More)
Based on tests with Falisan-Universal fluid caustic the authors report on measuring results of laboratory tests and analyses of utilization. The air pollution caused by the active agent phenyl mercury acetate and the formulation remedy dimethylformamide is assessed. Conclusions are made for the caustic's application and for its tests.
