The great but uncomplicated suggestion of introducing a catheter percutaneously into an artery, with no first dissecting it loose, utilizing a versatile advisor cord, has resulted in a very progressive 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 guides have seemed which take care of each available element of angiographic procedure and interpretation. This quantity is designed to provide our event with belly angiography. We intentionally avoided 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 zone relies often on its value in differential prognosis. In ten years of angiographic task, our division had made winning use of an easy method which seems compatible additionally for smaller hospitals. we want to indicate its diagnostic capability and, even as, to stipulate its barriers. Our adventure embraces 2804 stomach angiograms, which we've categorized 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 sort which we came across in our personal paintings. Angiographic prognosis calls for not just familiarity with common radiographic anatomy, but additionally particular wisdom of angiographic patho­ morphology. we've attempted to spot these positive factors which typify the person findings and to derive therefrom legitimate generalizations simply by basic sketches.

Example text

In the case of selective arteriography it is often possible to catheterize the celiac artery. Since the catheter tip lies beyond the stenosis, no abnormalities may be seen on such an angiographic series (REUTER and REDMAN, 1972). Injection of the superior mesenteric artery, however, generally shows filling of some or all of the celiac distribution through dilated, elongated pancreaticoduodenal arcades. Among chronic stenosing vascular diseases, arteriosclerosis (4) of degenerative or mixed degenerative-inflammatory origin occurs most frequently , at a 90% incidence as compared with about 10% for arteritis.

Among these factors, arterial embolism and thrombosis are about equally common, while the other causes are rare events (ZAHN and GOERTTLER, 1971). One possible exception is vascular injury due to abdominal trauma; at any rate, we have seen an increasing number of such alterations on our angiograms, notably in cases of ruptured spleen (cf.
