[Correlations between splenoportographic findings and risk of digestive hemorrhage in portal hypertension].

In 102 cases examined by splenoportography (93 cirrhosis with patent splenoportal axis and 9 splenoportal thrombosis without appreciable liver changes), the occurrence of episodes of digestive haemorrhage was statistically correlated with age, sex, type of portal impediment, type of collateral circulation, and the presence or otherwise of ascites, and with portal pressure values measured by splenomanometry. The only statistically significant correlation was that concerning the type of hepatofugal collateral circulation, as digestive haemorrhage proved gradually less frequent in patients with gastro-oesophageal collateral circulation, in those with so-called infraportal collateral circulation and, finally, in those where angiography was unable to demonstrate the presence of any collateral circulation at all.
