Imaging procedures in diagnosis of variceal hemorrhage

: Imaging procedures in patients suffering from portal hypertension and the problems arising from this condition are limited to the demonstration of the morphology of the collateral circulation towards the superior and the inferior vena cava. Imaging is essential prior to elective and emergency treatment of bleeding varices. Non-invasive and invasive imaging procedures are available. Acute hemorrhage of varices usually can not be demonstrated with any of the methods. Important is the preoperative evaluation of the portal system and the angiographic demonstration of the anatomy.
