Résumé
L’hémorragie par rupture de VO, complication fréquente responsable de 30 % de décès à la phase aiguë, est reliée à l’augmentation de la pression portale, la taille des varices et l’insuffisance hépatique. En l’absence de critères hémodynamiques fiables et facilement reproductibles, l’échoendoscopie va permettre une étude globale à la fois anatomique et hémodynamique du système porte et des veines de dérivation. Ces nouveaux éléments vont aider à sélectionner des patients à haut risque de saignement variqueux et adapter au mieux la prévention de l’hémorragie. L’EES va rechercher des facteurs prédictifs de mauvaise réponse aux traitements habituels et évaluer les possibilités de la mise en place d’un TIPS. Le traitement par ponction écho-guidée ou écho-assistée des varices profondes et en particulier des grosses veines pénétrantes est techniquement réalisable mais reste encore à évaluer.
Summary
Haemorrhage by rupture of OV is a frequent complication responsible for 30% of mortality in the acute phase. It is linked to the increase of portal pressure, the size of the varices and the hepatic insufficiency. In the absence of accurate and easily reproducible hemodynamic criteria, endoscopic ultrasonography allows for a global anatomic and hemodynamic study of the portal system and of the collateral veins. These new elements will help to select patients with high risk of variceal bleeding and to adapt the best strategy for preventing haemorrhage. EUS will be able to find the predictive factors of bad response to the usual treatments and to assess the possibilities to create a TIPS. The treatment by ultrasonographically guided or ultrasonographically assisted puncture of deep varices and mainly of penetrating large veins is technically possible but still needs to be assessed.
