Estimation of the relative liver perfusion using two methods of radionuclide angiography in the patients with hemodynamic disorders in the portal system.

The aim of this study is the assessment of the relative arterial and venous contribution to the total liver blood flow (hepatic perfusion index-HPI), with two methods (S1 and S2), and estimation of their value. With this correction, HPI nonsignificantly increases (p>0.05) in all the groups of patients, with a very high correlation between the HPI (S1) and HPI (S2) values (p<0.

[Surgery of abdominal aorta with horseshoe kidney].

Seventy one surgical procedures on abdominal aorta in patients with horseshoe kidney have been reported in literature until 1980. Bergan reviewed 30 operations of abdominal aortic aneurysms (AAA) in these patients until 1974. Of them 3 AAA were ruptured.

Study of portacaval shunt effectiveness in rats.

Background/aims: This is a report of a study designed to confirm the presence and determine the effectiveness of portacaval shunts.

Material And Methods: Color Doppler ultrasonography of the portal system, as a superior diagnostic procedure, was performed in experimental animals.

Results: Presence of shunt is indicated by initial loss of body mass in such animals (p < 0.
