The exceptional but basic notion of introducing a catheter percutaneously into an artery, with no first dissecting it unfastened, utilizing a versatile consultant cord, has ended in a very innovative step forward in belly x-ray diag­ nosis (SELDINGER, 1953). meanwhile, tools and strategies for injecting distinction media into a number of vessels became principally standardized; innumerable courses have seemed which take care of each feasible point of angiographic approach and interpretation. This quantity is designed to give our adventure with stomach angiography. We intentionally kept away from any systematic dialogue of the genitourinary tract, which has been safely handled within the literature, additionally with recognize to angiographic findings. Our curiosity within the retroperitoneal quarter is predicated generally on its value in differential analysis. In ten years of angiographic job, our division had made profitable use of an easy strategy which looks compatible additionally for smaller hospitals. we want to indicate its diagnostic strength and, whilst, to stipulate its boundaries. Our adventure embraces 2804 stomach angiograms, which we now have categorized in response to scientific and morphologic anatomical standards. Their diagnostic interpretation has been in comparison with the surgical or histopathological effects. this can support others to prevent blunders of the kind which we came across in our personal paintings. Angiographic prognosis calls for not just familiarity with general radiographic anatomy, but in addition particular wisdom of angiographic patho­ morphology. now we have attempted to spot these beneficial properties which typify the person findings and to derive therefrom legitimate generalizations using uncomplicated sketches.

As a result, the isotonic balance of the blood, disturbed by the high osmolarity of the contrast medium, is restored. Investigations by EFSEN and MUNKNER (I 968) demonstrated the effects of the osmolarity of the contrast medium by a measurable increase of cardiac output. This circulatory reaction is attributable solely to the hypertonic properties of the contrast medium. This is shown by the fact that injections of physiologic saline will cause a comparable, mechanically induced initial blood pressure rise without the subsequent hypotensive reaction or increase of cardiac output.

41 When we look into the question how such surveys are produced, the initial, relatively favorable impression is somewhat dimmed. Once the radiologist has made certain that there is no more bleeding from the puncture site and the foot or radial pulse is readily palpable, he generally loses sight of the angiographed patient very quickly. The patient is provided with a compression dressing and sand bag and returned to his ward or to the referring hospital; only if something out of the ordinary happens then is the radiologist notified of the complications, such as after bleeding, thrombosis, embolism, or the development of aneurysms at the puncture site (Fig.
