Résumé : The authors present a study of the correlation between portal pressure and the intra-varicose pressure in 30 patients suffering from cirrhosis with portal hypertension. The measurements were carried out by direct puncture in endoscopy of the varices and during the course of a sub-hepatic angiography. A positive correlation was observed between the pressure in the varices and the corrected sinusoidal pressure with the exception of patients studied in the course of digestive hemorrhage with rupture of the varices. They also show a gradient of pressure along the varicose columns. They discuss the results obtained on the basis of a selection of patients and other criteria not retained in their series in an attempt to define the relationship between portal hypertension and risk of hemorrhage with rupture of the varices. © 1984 Springer-Verlag.
