[Noninvasive imaging methods and angiography in the diagnosis of chronic viscero-visceral arterial collateral circulation in stenosis of the celiac trunk].

Abstract

Stenosis or even occlusion of truncus coeliacus represents the most frequent cause in the development of collateral blood circulation with caudiocranial flow through extended pancreatic-duodenal arcades. In a group of 32 patients with such mesenteric-coeliacal collateral circulation their arteriographic picture was evaluated. The authors evaluated differences and specific diagnostic contribution of individual visualization methods for demonstration of arteries. The non-invasive visualization methods are of exceptional contribution in the examination of abdominoretroperitoneal region by considerably decreasing the needs of invasive angiographic examination of catheterization technique. This leads to a decrease in the number of diagnosed chronically developed viscerovisceral arterial collateral circulations of various etiologies. Ultrasonography and computer tomography well depicts morphological changes in the aorta diameter as well as unpaired visceral arteries in the segment of their branching. The viscerovisceral arterial collateral circulations, however, may not be detected or at least not to a sufficient degree. They are represented in detail in the whole course only by selective arteriography. The authors draw attention to supplementary role of arteriography within the framework of non-invasive visualization methods.
