The remarkable but basic concept of introducing a catheter percutaneously into an artery, with no first dissecting it loose, utilizing a versatile consultant cord, has ended in a very innovative leap forward in stomach x-ray diag nosis (SELDINGER, 1953). meanwhile, tools and strategies for injecting distinction media into quite a few vessels became principally standardized; innumerable guides have seemed which take care of each possible element of angiographic approach and interpretation. This quantity is designed to provide our event with belly angiography. We intentionally kept away from any systematic dialogue of the genitourinary tract, which has been properly handled within the literature, additionally with appreciate to angiographic findings. Our curiosity within the retroperitoneal sector is predicated in most cases on its value in differential prognosis. In ten years of angiographic task, our division had made winning use of an easy strategy which looks compatible additionally for smaller hospitals. we want to indicate its diagnostic capability and, whilst, to stipulate its barriers. Our adventure embraces 2804 belly angiograms, which now we have labeled in response to 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 found 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 got attempted to spot these gains which typify the person findings and to derive therefrom legitimate generalizations through easy sketches.

The cosmic radiation used to be came across by means of Hess in 1912 yet its foundation remains to be the topic of a lot controversy and significant examine. For numerous many years such a lot employees within the cosmic ray box have been attracted to the Nuclear actual point of the particle beam and lots of vital dis coveries have been made, significantly the id of the positron, the muon, the pion and the unusual debris.
Blood platelets lack a nucleus. for that reason their lifestyles span is brief and so they can't reproduce themselves. Platelets percentage those traits with the pink blood mobilephone. Plate we could and purple blood cells, however, serve important roles within the physique. One significant functionality of the platelet is its skill to mixture and thereby start up intravas cular coagulation which regularly underlies such significant illnesses as myocardial infarc tion, cerebral infarction, and pulmonary embolism.

For selective arteriography. we used catheters with only an end hole. Injections were manual in these examinations as well as in translumbar aortography. The contrast medium volumes ranged from 10 to 50 ml and. for survey aortographies. between 35 and 60 m!. Blood pressure was measured within the vessel with a Statham gauge and recorded on a Hellige four-channel recorder. A characteristic blood pressure curve with the corresponding roentgenogram is shown in Fig. 36. Here, two needles were introduced separately for injection of contrast medium and for measurement of blood pressure.

Other authors who have helped to perfect this angiographic method of localizing intestinal bleeding may be found in the English-language literature (ANNES et al.. 1967; BOUSEN and REUTER. 1967; KOEHLER and SALOMON. 1967; HALPERN et al.. 1968; REUTER and BOOKSTEIN. 1968).
