New diagnostic and screening possibilities in the stenobliterative lesions of the deep visceral vessels.
The evolution and continuous improvement of the ultrasonic diagnostic devices allows an hemodynamic and morphological exploration of the deep abdominal vessels that until now seemed to be precluded to non invasive diagnostic techniques. For example, the angiodynography today advantageously substitutes classical urographic investigation during the initial screening of the hypertensive patients suspected of stenotic lesions of the renal arteries. In fact the ecocolordopplersonography allows not only a morphological evaluation of the parenchyma and of the renal vascular tree, but also supplies a quantitative measurement of the blood flow through the renal artery. Still more important are the possibilities offered by these devices in the study of the acute or chronic intestinal ischemia, in which until now a sure diagnosis was only possible using invasive techniques. Performing a study of the mesenteric vascularization urgently, sometimes is possible a decisive demonstration of an ischemic pathology where the clinical abdominal picture provides only uncertain diagnostic elements.
