title: [Roentgen findings in the full-size abdominal radiograph in occlusion syndromes at the visceral aortic branches (author's transl)].
abstract: The acute visceral ischaemia syndrome (which, in typical cases, is caused by embolism or thrombosis of the arteria mesenterica cranialis or, in some cases, by a functional reduction of flow in that vascular area), is usually assigned to the roentgenologist under the heading "acute abdomen" for effecting an abdominal fullsize radiograph. Although this does not allow safe diagnosis and differential diagnosis, it does provide valuable pointers in quite a number of cases. One of the most specific symptoms is the so-called flexure cut-off symptom consisting of a pronounced accumulation of gas (wind) from the caecum to the left flexure. a typical case and one each similar case in a chronic visceral triple occlusion and a polycythaemia, are demonstrated. The mandatory diagnostic consequence of this symptom is immediate aorto-arteriography unless a functional cause is evident and can be successfully treated by conservative measures.
