[Diagnostic value of selective angiography in the pancreatic affections (author's transl)]

A retrospective study of selective angiography of the coeliac axis and superior mesenteric artery was conducted in 60 patients having a pancreatic disease. The purpose of this study was to precise the frequency, the specificity and the diagnostic value of each radiological sign in malignant and non malignant pancreatic affection. In patients with cancer of pancreas, the best radiological sign are the presence of an arterial obstruction, an irregular arterial stenosis, a venous obstruction or a parenchymal hypervascularization. In patients with benign affections, the most significant signs are á regular arterial stenosis alore or associated with an arterial involvement or the association of at least two of the three following signs: regular arterial stenosis, arterial involvement and venous compression. Using this signs, a correct diagnosis can be done, a posteriori, in 82% of the malignant pancreatic affections and in 76% of the benign pancreatic disease.
