Value of vascular morphology for the selection of catheters in selective celiacography and mesentericography

Abstract

By means of 192 lateral aortograms the vascular morphology of the coeliac and superior mesenteric artery were correlated to age, sex and body weight. Independently of these parameters 90% of the exit angles of the coeliac artery were situated between 15 degrees and 90 degrees with a median of 45 degrees. In persons with less than 65 kg body weight the median origin angle of the superior mesenteric artery corresponded to 45 degrees, too, whereas in heavier patients they were bigger (60 degrees). The vascular diameter and the further course of the superior mesenteric artery significantly depended on the constitutional type. In 40.5% we saw a cranial eccentric stenosis of the coeliac artery. Frequency and intensity were not influenced by age, sex or body weight, but accompanied by smaller origin angles of the coeliac artery and bigger ones of the superior mesenteric artery. In conclusion different catheter shapes in dependence of the constitutional type are recommended for combined coeliac and mesenteric angiography.
