Floating viscera sign
Updates to Article Attributes
TheFloating Viscera Sign floating viscera sign is an angiographic signs manifested by visulaizationsign that occurs when there is visualisation of brnachesbranches of the abdominal aorta including celiac (e.g. coeliac axis, superior mesenteric artery, and renal arteries) during aortographywith little or no clear visualizationvisualisation of aortic lumen while the cather within aortic true lumen.
it indicates the presence of an aortic dissection and associated dynamic compromisecompression of the aortic true lumen and associated visceral branch vesselsby the false lumen upstream from the origins of the mesenteric arteries. When it occurs, it indicates that the catheter is located within aortic true lumen, downstream from a hemodynamically significant false lumen.
