[Experimental detection of hemorrhage in the circulation area of the superior mesenteric artery by intra-arterial nuclide angiography].

A new experimentally proven method for diagnosis and localisation of acute bleeding in the flow area of the arteria mesenterica superior is reported. By selective intra-arterial nuclide injection microhemorrhage below the proof limit of angiography can be registered and relatively exact localized by additional geometric procedure. Using this method, the exact location of angiographic, negative bleedings could be determined in experimentally produced bleedings in the jejunoileal transit and in the distal ileum. We explain the experimental arrangement and the results. The diagnostic value of the examination is discussed.
