Résumé
Les auteurs rapportent une étude de corrélation entre la pression portale et la pression intra-variqueuse chez 30 patients cirrhotiques avec hypertension portale. Les mesures ont été effectuées par ponction directe per-endoscopique des varices et au cours d’une angiographie sus-hépatique. Une corrélation positive est observée entre la pression dans les varices et la pression sinusoïdale corrigée, ð l’exception des patients étudiés au décours d’une hémorragie digestive sur rupture de varices. Ils mettent également en évidence un gradient de pression au long des colonnes variqueuses. Ils discutent les résultats obtenus sur base de la sélection des patients et de critères non retenus dans leur série pour tenter de définir la relation hypertension portale - risque hémorragique sur rupture de varice.
Summary
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.
