Pancreaticoduodenal artery aneurysm can occur from occlusion or stenosis of the celiac artery due to arteriosclerosis or median arcuate ligament compression. The risk of rupture of the aneurysm is independent of the aneurysmal diameter. A 78-year-old woman presented with multiple large aneurysms of the anterior superior pancreaticoduodenal artery. To preserve arterial flow to the liver, bypass grafting from the supra-celiac aorta to the common hepatic artery was performed at first. Coil embolization was successfully performed 10 days later with a dual approach through both the superior mesenteric artery and bypass. It was considered that the combination of the aorto-hepatic bypass and coil embolization was effective for the pancreaticoduodenal artery aneurysms due to celiac artery occlusion.
The pathogenesis of psoriasis is still an enigma, although deregulation of nuclear factor κB signaling and resulting abnormal cytokine secretion are speculated to be involved. Ceramics may affect these signaling events and cause the onset of psoriasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
