[Comparison of echo-Doppler and splenoportography in the hemodynamic evaluation of the portal system]. / Confronto tra eco-Doppler e splenoportografia nella valutazione emodinamica del circolo portale.

The Authors discuss the instrumental diagnosis of portal hypertension, comparing echo-Doppler and splenoportography by celiac artery catheterization, performed on 42 patients with cirrhosis. From the data obtained, there may be observed a clear correlation between angiographic and echographic criteria, correlated to the degree of illness. In particular echo-Doppler whether it possible, in a non-invasive way, to control the evolution of progressive haemodynamic resistance, and hepatic and splenic parenchyma, leaving to splenoportography the role to depict anatomic characteristics of portal circulation for a correct surgical program.

[Diagnostic "gold standard" in cerebrovascular insufficiency. Comparison of angiographic and ultrasonic imaging]. / "Gold standard" diagnostico nella ICV. Imaging angiografico e ultrasonico a confronto.

The Authors consider the complex diagnostic problems of cerebrovascular disorders, with particular concern to angiography and echography. After a complete analysis of different aspects of angiographic and echographic lesions, considering their experience, they identify chances and limits of the two methods, they draw the conclusion that each of the two techniques has a proper role, and only a correct correlation between them can depict correctly the pathologic lesions.
