The great but basic inspiration of introducing a catheter percutaneously into an artery, with no first dissecting it unfastened, utilizing a versatile consultant cord, has resulted in a really innovative leap forward in belly x-ray diag­ nosis (SELDINGER, 1953). meanwhile, tools and strategies for injecting distinction media into a number of vessels became mostly standardized; innumerable courses have seemed which take care of each attainable element of angiographic approach and interpretation. This quantity is designed to give our adventure with stomach angiography. We intentionally avoided any systematic dialogue of the genitourinary tract, which has been correctly handled within the literature, additionally with recognize to angiographic findings. Our curiosity within the retroperitoneal quarter is predicated in general on its value in differential prognosis. In ten years of angiographic task, our division had made profitable use of an easy method which seems to be compatible additionally for smaller hospitals. we want to indicate its diagnostic strength and, whilst, to stipulate its barriers. Our event embraces 2804 stomach angiograms, which we've got categorised in accordance with medical and morphologic anatomical standards. Their diagnostic interpretation has been in comparison with the surgical or histopathological effects. this can aid others to prevent mistakes of the kind which we chanced on in our personal paintings. Angiographic analysis calls for not just familiarity with basic radiographic anatomy, but additionally particular wisdom of angiographic patho­ morphology. we've attempted to spot these good points which typify the person findings and to derive therefrom legitimate generalizations due to easy sketches.

No doubt, isolated observations of this kind do not by themselves constitute proof. However, SCHIMANSKI and SCHMIDT (1971) carried out a very critical review of the literature on occlusion or stenosis of a single visceral artery associated with clinical symptoms, and were able to cite a number of relevant papers (op. ). They themselves found among 16 cases of visceral circulatory insufficiency 9 patients with isolated stenosis or occlusion of the main trunk of a visceral artery. In seven cases, 2 or 3 arteries were stenosed.
