[Evaluation of the arterial share of portal flow using a scintigraphic technique in patients with liver cirrhosis. Correlations with other parameters of portal hypertension].
This study aimed to measure in semiquantitative terms the arterial-venous ratio of the portal flow using a scintigraphic technique, by means of a simple intravenous injection of a 99mTcDiethylHIDA bolus, a method which was found to be extremely simple and non-invasive, with a good degree of repeatibility. The percentage of arterialisation of the portal flow was found to be higher in cirrhotic patients compared to non-hepatopathic subjects, and among cirrhotic patients it was correlated with the severity of disease, the presence and degree of esophageal varices, and the presence of porto-systemic shunts, assessed using the ammonium chloride test.
